Geology

Alteration processes:Propylitic alteration consisting of various combinations of epidote, chlorite, pyrite, and magnetite is widespread. Quartz-sericite-pyrite, magnetite-plagioclase, and potassic (biotite) assemblages are also present. .Alteration zoning is poorly understood due primarily to lack of outcrop. One zoning sequence of increasing intensity consists of epidote-pyrite to chlorite-pyrite to chlorite-magnetite.
