Geology
Host rockSandstone,Limestone · "Rib Hill Sandstone", "Riepe Spring Limestone"
Associated rockQuartz Monzonite,Porphyry
StructureNumerous faults cut the rocks in the mine area., In mid-Cretaceous time, Paleozoic miogeosynclinal sedimentary rocks were deformed into an overturned E-W-trending anticline whose upper limb was thrust to the southwest. Basin-and-Range normal faulting successively down-dropped the upper portions of the system to the east.
AlterationThe main alteration is decalcification and silicification of limestone, ad rocks are also localyaffected by advanced argillic alteration.
