Geology

Alteration processes:

The stock is altered to an assemblage of sericite, chlorite, clay minerals, and secondary silica. Only traces of the original textures are preserved in most places but breccia textures characterize several samples from the area (Patton and Csejtey, 1971, Table 1). The altered rocks are highly oxidized and well developed limonite staining and veining makes the stock conspicuously visible from a distance due to its red and orange color.
