Geology

Host rock:	Sedimentary Rocks;Metasedimentary Rocks
Host type:	Dacite
Associated rock:	Quartz Intrusive (Plug) In Dacitic Porphyry;Dacitic Porphyry;Tuffs
Associated type:	Mafic Intrusive Rock,Dacite
Structure:	N-Trending Folded And Faulted Ranges East Of Principal Cordillera. Pal Rocks Intruded By Intermediate To Felsic Plutons. Faults Of 5000-M Displacement On Eastern Frontal Cordillera, Dacitic Porphyry Intrudes Older Rocks & Is Cut By Small Nnw & Nne-Striking Basalt Dikes Faults And Fractures Of Quartz-Calcite Veinlets Are In Area. In Center Of Dacitic Porphyry Is Intrusive Plug Of Massive Barren Quartz, 200 M N-S, 60 M Across, Which Dominates Relief
Tectonic:	Frontal Cordillera
Alteration processes:	Bleached Zone 200 X 500 M Around Quartz Plug. Hydrothermal Alteration Of Dacitic Porphyry Evidenced By Bleaching And Leaching. Process Probably Accompanied By Direct Magmatic Activity Of Late Residual Fluids Injected Into Rock. Zone Of Silicification Mapped.
