Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Deposit): MUCH OF INTERIOR OF SINBAD VALLEY CONSISTS OF DEFORMED PENNSYLVANIAN EVAPORITES, SOME IN FAULT CONTACT WITH TRIASSIC AND PERMIAN RED BEDS. ALONG SOUTH AND SW SIDE OF GRABEN, TRIASSIC RED BEDS COMPLEXLY FAULTED WITH JURASSIC SANDSTONES AND SHALES. DISSEMINATED CU SULFIDES OCCUR IN WINGATE SANDSTONE AND KAYENTA FM (JURASSIC) SANDSTONE ALONG FAULTS. ORE CONSISTS OF CHALCOCITE, MALACHITE, AND AZURITE IMPREGNATING SANDSTONE IN LAYERS AND SMALL IRREGULAR BODIES. AT MAIN ADITS CU OCCURS AT INTERSECTIONS OF FAULTS WITH PARADOX MEMBER LIMESTONE, ALSO ALONG FRACTURES AND JOINTS.
