Geology

Alteration processes:Alteration of granodiorite host rock is limited to partial alteration (?) of amphibole to biotite and slight chloritization of biotite. Clasts of granodiorite in the breccia pipe exhibit propylitic alteration. Biotitic and sericitic alteration occur as thin selvages along veinlets.
