Geology

Alteration processes:

Potassic alteration with the introduction of K-feldspar and biotite occurs in the core of the system. Locally the rocks are sericitized and phyllically altered. Higher in the system, the rocks are silicified, altered to clay, and carbonatized. Bull and her co-authors (1997 and 1999) indicate that galena is more abundant distally.
