Propylitic and Argillic Alterations above Henderson

Looking for two types of hydrothermal chemical alteration and is an important indicator of potential mineralization:

Propylitic - altering biotite or amphibole into epidote, chlorite, or albite. Looks to me like epidote alteration shown here.

This was the Alunite Mining District of 1905... the first scientific gold prospect ever... not... but he did recover in Texas oil.

Argillic - altering feldspar and quartz into clay minerals like alunite, illite, kaolinite, and dickite probably with the help of acidic sulfurs.
