Geology

Alteration processes:

Granodiorite, in general, is moderately propylitically altered, and contains traces of disseminated pyrite. Locally, granodiorite is completely propylitically altered, having up to 4 percent pyrite either disseminated or in fracture fillings. Although andesitic country rocks generally are not altered, they locally contain zones of intense alteration (destruction of feldspars and mafic minerals) up to 20*(60 m) wide containing as much as 5 percent pyrite.
