A Thunderegg is a geological structure similar to a geode but with unique characteristics. Here's an overview: Formation: Thundereggs form within rhyolitic volcanic ash layers. They start as gas bubbles or steam pockets in the lava, which act as molds. Over time, these are filled with silica-rich fluids, mainly chalcedony, agate, jasper, or opal, creating intricate patterns and colors inside. Appearance: On the outside, thundereggs look like ordinary, rough-textured rocks, often with a white-gray to reddish-brown surface. However, when cut and polished, they reveal a variety of internal structures, from solid agate or chalcedony cores to sometimes hollow centers with crystals. Size: They can range from small, about the size of a baseball, to larger specimens over a meter across, though most commonly they are between two to six inches in diameter. Locations: While Oregon, USA, is particularly famous for thundereggs, especially in counties like Crook, Jefferson, Malheur, Wasco, and Wheeler, they are found globally wherever the geological conditions are right. Other notable locations include Germany, Australia, Brazil, Canada, Mexico, Poland, Romania, and Turkey. Cultural Significance: In Oregon, the thunderegg was designated as the state rock in 1965, reflecting its importance in local geology and culture. Native American legends attribute their formation to thunder spirits or gods throwing these rocks during thunderstorms. Collection and Use: Thundereggs are popular among rock collectors for their unique beauty once cut open. They're often used in jewelry making or as display pieces due to their aesthetic appeal after being sliced and polished. Variations: Each thunderegg is unique due to the minerals present in the area where it forms, leading to a wide variety in color, pattern, and structure even from the same bed. This gives you a comprehensive view of what a thunderegg is, its formation, and its significance.

Opal is a hydrated amorphous form of silica, with a water content typically between 3 and 21% by weight, most commonly around 6-10%. It's deposited at relatively low temperatures and can be found in the fissures of various rock types, including limonite, sandstone, rhyolite, marl, and basalt. Here's a deeper look into opal: Types of Opal: Precious Opal: Known for its "play-of-color," which is an optical phenomenon where colors flash or change as the angle of light or observation changes. This effect is due to the diffraction of light through the microscopic silica spheres within the opal. Common Opal: Lacks the play-of-color and can come in a variety of colors like white, black, grey, yellow, orange, red, or brown. It's often referred to as "potch" when not gem-quality. Fire Opal: Typically ranges in color from yellow to orange to red and can be transparent to translucent. Fire opals can exhibit play-of-color, but their name comes from the fiery body color. Boulder Opal: A type of opal naturally attached to its host rock. It's often cut with the host rock to provide stability and to enhance the visual appeal. Matrix Opal: The opal fills the cracks and cavities within the host rock, creating a network of opal that's visible on the surface. Formation: Primary Opal: Forms through the slow deposition of silica from groundwater in cavities or fractures of rocks. Secondary Opal: Can form by weathering or alteration of other minerals, often in more superficial environments or through the action of silica-rich waters. Locations: Australia: The world's leading source, especially for precious opal, with significant deposits in places like Coober Pedy, Lightning Ridge, and White Cliffs. Ethiopia: Known for its black opals and more recently discovered opal fields. Mexico: Famous for fire opals. Brazil: Produces a variety of opals, including crystal opal. Properties: Hardness: Typically ranges between 5.5 to 6.5 on the Mohs scale, though it can be softer if less hydrated or harder if more silica-rich. Luster: Can range from waxy to resinous to vitreous. Transparency: Varies from opaque to semi-translucent to transparent.

The rock appears to be a type of jasper, specifically "picture jasper" or "brecciated jasper." Here's why: Color and Pattern: The rock has a mix of earthy tones, predominantly red, brown, and white, which is typical for jasper. The red color often comes from iron inclusions. Texture: Jasper is usually opaque and has a waxy luster, which seems consistent with the appearance of this rock. The brecciated (broken and re-cemented) texture is also a characteristic of some forms of jasper. Formation: Jasper forms from silica-rich waters that fill cavities or fractures in rocks, often leading to the layered or mottled appearance seen here. Commonality: Jasper is a common rock used for various decorative purposes due to its color and pattern, making it a likely candidate for a rock of this appearance. If you're looking for a precise identification or valuation, taking the rock to a geologist or a gemologist could provide more detailed information, especially if you're considering it for any specific use or sale. However, visually, it strongly resembles jasper based on its color palette and texture.

This rock appears to be a type of geode, specifically an agate geode. The outer part is typically composed of a layer of chalcedony, which is a form of silica, often found in volcanic and metamorphic rocks. The inside, as seen in the photo, shows botryoidal formations, which are grape-like clusters, commonly formed by the deposition of minerals from groundwater within the cavities of the rock. The white and translucent nature of the interior suggests it could be lined with quartz or agate, which often forms in such structures. These formations are prized for their beauty and are often cut and polished for use in jewelry or as decorative pieces.

Plume agate is a variety of chalcedony, a microcrystalline quartz, characterized by delicate, plume-like inclusions of various colors and minerals. These inclusions often resemble feathers, flowers, or flames, giving the agate a unique and visually appealing appearance. Plume agate only forms in hotsprings with the help of thermophiles and extremophiles (microscopic organisms that like harsh and hot environments) collecting silica and other dissolved particles in silica rich hotsprings and depositing them in wild patterns within the agate. A combination of clays, metals and minerals make up the cool colors and textures we experience. There are many famous deposits of plume, flame and other varieties of textures made with the assistance of microbes.

The rock appears to be a type of jasper, specifically "picture jasper" or "brecciated jasper." Here's why: Color and Pattern: The rock has a mix of earthy tones, predominantly red, brown, and white, which is typical for jasper. The red color often comes from iron inclusions. Texture: Jasper is usually opaque and has a waxy luster, which seems consistent with the appearance of this rock. The brecciated (broken and re-cemented) texture is also a characteristic of some forms of jasper. Formation: Jasper forms from silica-rich waters that fill cavities or fractures in rocks, often leading to the layered or mottled appearance seen here. Commonality: Jasper is a common rock used for various decorative purposes due to its color and pattern, making it a likely candidate for a rock of this appearance. If you're looking for a precise identification or valuation, taking the rock to a geologist or a gemologist could provide more detailed information, especially if you're considering it for any specific use or sale. However, visually, it strongly resembles jasper based on its color palette and texture.

This rock has characteristics that suggest it could be a type of brecciated jasper or agate. Here are the reasons for this identification: Texture and Appearance: The rock has a mix of colors, predominantly white with patches of brown, red, and possibly some darker inclusions. This mottled appearance with different colored sections embedded within a matrix is typical of brecciated materials. Brecciation: The rock appears to have a brecciated texture, where there are fragments of one material (likely agate or jasper) embedded in a matrix of another. This can happen due to geological processes like faulting or intense weathering. Silica Content: Jasper and agate are both forms of chalcedony, which is a type of silica. The shiny, somewhat translucent appearance of parts of the rock aligns with the properties of chalcedony. Commonality: Jasper and agate are common and widely found, often appreciated for their decorative qualities due to their color and pattern. If this rock was found in a specific location known for certain types of rocks, or if you're looking for a more precise identification, details about its origin or taking it to a local geologist or gemologist could provide more accurate information. However, based on the visual characteristics from the image, brecciated jasper or agate seems a likely identification.

This rock appears to be a type of jasper possibly a form with agate banding. Here are the characteristics that lead to this identification: Coloration: The rock has a rich, warm coloration with shades of grey, purple, beige, and creme which are popular in jaspers due to iron oxide inclusions. Translucency: Some parts of the rock are translucent, which is a common trait in agates. This translucency often comes from chalcedony, a form of silica. Banding: The rock shows banding patterns, which are characteristic of agates where layers are formed by the deposition of silica from groundwater in cavities of volcanic rocks. Texture: The surface appears somewhat polished, which is often done to enhance the natural beauty of agates and jaspers. Given these features, it's likely that this rock is jasper. Agates are known for their fine grain and bright, contrasting colors, which aren't seen in this specimen.

The Graveyard Point area is seven miles from Homedale, Idaho, just two miles across the Idaho-Oregon border. There have been numerous different claims and mining operations in this area, including the Linda Marie and Beverly Marie claims. Graveyard Point Plume Agate is a well-known seam agate found in far eastern Oregon. - https://www.google.com/search

The rock in the image appears to be a type of quartzite. Quartzite is a metamorphic rock that forms from the metamorphism of quartz sandstone. It's primarily composed of quartz grains that have been recrystallized under heat and pressure, giving it a hard, durable nature and often a somewhat glassy luster. The colors and patterns you see, with light colors and darker veins, are typical of quartzite, which often retains some of the original sedimentary layering or banding from its sandstone precursor but in a more compact and crystalline form. The presence of different shades like white, beige, and possibly some iron staining or other mineral inclusions could give it the varied coloration seen here.

The rock in the image appears to be a type of chalcedony, possibly an agate or a similar variety. Here's why: 1. **Coloration and Banding**: The rock has a predominantly white or light gray color with some yellowish-brown inclusions. This kind of coloration and banding is typical for agates, which are a variety of chalcedony. 2. **Translucency**: Chalcedony, including agate, often has a translucent quality, which seems to be present in parts of this rock. 3. **Texture**: The rock's texture looks somewhat waxy or greasy, which is characteristic of chalcedony due to its fine-grained silica composition. 4. **Inclusions**: The yellowish-brown areas could be iron oxide or other mineral inclusions, which are common in agates and give them their varied colors. However, without specific tests like a hardness test, streak test, or chemical analysis, this identification remains speculative. For a more precise identification: - **Hardness Test**: Chalcedony has a hardness of around 7 on the Mohs scale, meaning it should scratch glass but not be scratched by a knife. - **Streak Test**: The streak of chalcedony (if it could be powdered) would typically be white or colorless. - **Microscopic Analysis**: Looking at thin sections under a microscope could reveal the mineral composition more clearly. - **Consulting a Geologist or Using Spectroscopy**: For a definitive identification, especially if this rock might be of value or scientific interest.

If we consider the rock in the image to be quartz or a variety of quartz, here's how it might fit: 1. **Chalcedony**: As mentioned earlier, chalcedony is a type of quartz, specifically microcrystalline quartz. Its appearance can range from translucent to opaque, with colors influenced by impurities. The smooth, somewhat waxy luster and the mix of white with yellowish-brown in your rock could indeed fit chalcedony. 2. **Agate**: If there's any subtle banding not clearly visible in the image, it could be agate, a variety of chalcedony known for its fine grain and bright, attractive colors, often with bands or layers. 3. **Opal**: While not typically classified as quartz, opal can be associated with quartz deposits. However, its characteristic feature is its play-of-color, which isn't evident here. If it's common opal or opalite, it might lack this feature but still be related to quartz in geological context. 4. **Quartzite**: This is a metamorphic rock derived from sandstone, which is primarily quartz grains. If your rock has been subjected to metamorphism, the texture and color could be consistent with quartzite, especially if there's been some iron staining or if it's not fully recrystallized. 5. **Milky Quartz**: If the rock has a significant white component, it could be milky quartz, which is quartz with microscopic inclusions that give it a cloudy appearance. Given the context of quartz: - **Chalcedony or Agate** seem like the most fitting categories for your rock if we're considering varieties of quartz. The smooth texture, potential for banding (even if not clearly visible in the image), and the color variation are all consistent with these forms. Your rock's appearance aligns well with being a variety of quartz, particularly something like chalcedony or agate, based on its visual characteristics.

The rock in the image appears to be a type of **thunder egg** or **agate**. Here's why: 1. **Coloration and Banding**: The rock shows a combination of colors, including brown, white, and possibly some hints of other colors, which is typical for agates and thunder eggs. The banding pattern is also characteristic of agates, which form in cavities of volcanic rocks. 2. **Translucency**: Some parts of the rock are translucent, which is common in agates due to their chalcedony composition. 3. **Texture**: The rock's texture looks somewhat waxy or glassy, which is typical for agates that have been polished or naturally worn smooth. 4. **Inclusions**: The yellowish or brownish areas could be due to iron oxide or other mineral inclusions, which are often found in agates. Thunder eggs are nodules of agate found in volcanic rocks, and they often have a hollow or partially hollow interior filled with crystals or banded agate. However, without specific tests like a hardness test, streak test, or chemical analysis, this identification remains speculative.

Remember, rock identification can be complex due to the natural variability and the presence of multiple minerals in one specimen. Visual characteristics alone can sometimes lead to misidentification. Opal is a hydrated amorphous form of silica, with a water content typically between 3 and 21% by weight, most commonly around 6-10%. It's deposited at relatively low temperatures and can be found in the fissures of various rock types, including limonite, sandstone, rhyolite, marl, and basalt. Here's a deeper look into opal: Types of Opal: Precious Opal: Known for its "play-of-color," which is an optical phenomenon where colors flash or change as the angle of light or observation changes. This effect is due to the diffraction of light through the microscopic silica spheres within the opal. Common Opal: Lacks the play-of-color and can come in a variety of colors like white, black, grey, yellow, orange, red, or brown. It's often referred to as "potch" when not gem-quality. Fire Opal: Typically ranges in color from yellow to orange to red and can be transparent to translucent. Fire opals can exhibit play-of-color, but their name comes from the fiery body color. Boulder Opal: A type of opal naturally attached to its host rock. It's often cut with the host rock to provide stability and to enhance the visual appeal. Matrix Opal: The opal fills the cracks and cavities within the host rock, creating a network of opal that's visible on the surface. Formation: Primary Opal: Forms through the slow deposition of silica from groundwater in cavities or fractures of rocks. Secondary Opal: Can form by weathering or alteration of other minerals, often in more superficial environments or through the action of silica-rich waters. Locations: Australia: The world's leading source, especially for precious opal, with significant deposits in places like Coober Pedy, Lightning Ridge, and White Cliffs. Ethiopia: Known for its black opals and more recently discovered opal fields. Mexico: Famous for fire opals. Brazil: Produces a variety of opals, including crystal opal. Properties: Hardness: Typically ranges between 5.5 to 6.5 on the Mohs scale, though it can be softer if less hydrated or harder if more silica-rich. Luster: Can range from waxy to resinous to vitreous. Transparency: Varies from opaque to semi-translucent to transparent.

Jasper is a type of sedimentary rock, classified as a variety of chalcedony, which is a microcrystalline form of quartz; it's essentially an opaque, fine-grained aggregate of quartz with various impurities that give it its distinctive colors and patterns. Key points about jasper: Composition: Primarily made up of microcrystalline quartz with impurities that cause its opacity and color variations. Appearance: Usually opaque, with colors ranging from red, yellow, brown, green, and rarely blue. Formation: Often formed from volcanic ash deposits where silica-rich material settles and solidifies. Variety of types: Different names like "picture jasper," "bloodstone," "mookaite" are given based on color patterns and origin.

For a more precise identification: - **Hardness Test**: Chalcedony has a hardness of around 7 on the Mohs scale, meaning it should scratch glass but not be scratched by a knife. - **Streak Test**: The streak of chalcedony (if it could be powdered) would typically be white or colorless. - **Microscopic Analysis**: Looking at thin sections under a microscope could reveal the mineral composition more clearly. - **Consulting a Geologist or Using Spectroscopy**: For a definitive identification, especially if this rock might be of value or scientific interest.

The rock in the image appears to be a type of chalcedony, possibly an agate or a similar variety. Here's why: 1. **Coloration and Banding**: The rock has a predominantly white or light gray color with some yellowish-brown inclusions. This kind of coloration and banding is typical for agates, which are a variety of chalcedony. 2. **Translucency**: Chalcedony, including agate, often has a translucent quality, which seems to be present in parts of this rock. 3. **Texture**: The rock's texture looks somewhat waxy or greasy, which is characteristic of chalcedony due to its fine-grained silica composition. 4. **Inclusions**: The yellowish-brown areas could be iron oxide or other mineral inclusions, which are common in agates and give them their varied colors.

Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, CaMg(CO3)2. Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, for limestone containing significant dolomite (dolomitic limestone), or for any other limestone containing a significant percentage of magnesium. Most limestone was formed in shallow marine environments, such as continental shelves or platforms, though smaller amounts were formed in many other environments. Much dolomite is secondary dolomite, formed by chemical alteration of limestone. Limestone is exposed over large regions of the Earth's surface, and because limestone is slightly soluble in rainwater, these exposures often are eroded to become karst landscapes. Most cave systems are found in limestone bedrock. Limestone has numerous uses: as a chemical feedstock for the production of lime used for cement (an essential component of concrete), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paint, as a soil conditioner, and as a popular decorative addition to rock gardens. Limestone formations contain about 30% of the world's petroleum reservoirs

Jellybean agate is a gemstone that can be cut into cabochons and set in sterling silver to create jewelry pendants. It's available in a variety of colors, including: Aquamarine agate, which is greenish blue Lilac agate, which is light pink or lavender Raspberry agate, which is hot pink Sky blue agate, which is soft blue Violet agate Jellybean agate can also be purchased as beads. For example, The Bead Traders sells 17–20 mm multi-colored agate plain jelly bean beads. Etsy also sells jelly bean agates, including unique or custom, handmade pieces. Agate prices are generally modest, reflecting the cost of labor and artistry rather than the value of the material itself. Agates that are larger or have distinctive color patterns are more valuable

The rock shown in this image has a banded appearance with red, brown, and possibly some lighter or grayish bands. This pattern is characteristic of a type of rock called "banded iron formation" or BIF, but it could also resemble the appearance of certain types of jasper, particularly when it has a banded or layered structure due to different mineral compositions or oxidation states. Here's a breakdown of what it could be: 1. **Banded Iron Formation (BIF):** These are distinctive units of sedimentary rock that are almost exclusively of Precambrian age. They are composed of alternating layers of iron oxides and iron-poor chert, often showing a variety of colors from red to brown to black depending on the oxidation state of the iron. 2. **Banded Jasper:** Jasper can sometimes form in layers or bands due to variations in mineral content during its formation. The red color typically comes from iron inclusions, and the banding could be due to changes in the deposition environment over time. 3. **Agate:** While less likely given the color, some agates can have a similar banded appearance but are usually more translucent or have a wider variety of colors due to different silica deposition environments. Given the rock's rough texture and the color pattern, it's more likely to be a form of jasper or an iron-rich sedimentary rock like a banded iron formation.

Plume agate is a variety of chalcedony, a microcrystalline quartz, characterized by delicate, plume-like inclusions of various colors and minerals. These inclusions often resemble feathers, flowers, or flames, giving the agate a unique and visually appealing appearance. Plume agate only forms in hotsprings with the help of thermophiles and extremophiles (microscopic organisms that like harsh and hot environments) collecting silica and other dissolved particles in silica rich hotsprings and depositing them in wild patterns within the agate. A combination of clays, metals and minerals make up the cool colors and textures we experience. There are many famous deposits of plume, flame and other varieties of textures made with the assistance of microbes.

A cave or cavern is a natural void under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking. Formation types The formation and development of caves is known as speleogenesis; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the timescale of the geological events which formed and shaped present-day caves. It is estimated that a cave cannot be more than 3,000 metres (9,800 ft) vertically beneath the surface due to the pressure of overlying rocks. This does not, however, impose a maximum depth for a cave which is measured from its highest entrance to its lowest point, as the amount of rock above the lowest point is dependent on the topography of the landscape above it. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonaterocks. Most caves are formed in limestone by dissolution. Caves can be classified in various other ways as well, including a contrast between active and relict: active caves have water flowing through them; relict caves do not, though water may be retained in them. Types of active caves include inflow caves ("into which a stream sinks"), outflow caves ("from which a stream emerges"), and through caves ("traversed by a stream"). Speleothems in Hall of the Mountain King of Ogof Craig a Ffynnon, a solutional cave in South Wales. Solutional cave Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum. Except for salt caves, solutional caves result when rock is dissolved by natural acid in groundwater that seeps through bedding planes, faults, joints, and comparable features. Over time cracks enlarge to become caves and cave systems. The largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called speleothems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded.
