Massive Landslide In Kennecott Copper Bingham Canyon Mine, Oquirrh Mountains, Salt Lake City, Utah, United States

The oldest rocks at Bingham Canyon--sandstones, quartzites and limestones—were originally deposited as sediment by the shallow seas that covered the region 300 million years ago (in the late Paleozoic Era). Much later, between 60 and 135 million years ago, extensive folding and faulting of the sediments created the Oquirrh Mountains.
Thirty to 40 million years ago, massive igneous intrusions initiated the process of mineralization. Extreme pressure forced superheated, mineral-rich solutions into fractured intrusive and adjacent sedimentary rock. Upon cooling, the mineralized solutions deposited enormous quantities of metals throughout a broad section of igneous and sedimentary rock that is now known as the Bingham Stock.
Bingham Canyon is not presently a source of notable mineral specimens. The Bingham Stock is a porphyry deposit, meaning that copper minerals—primarily chalcopyrite—are present in very low grades and disseminated throughout the granite-like host rock as tiny grains, seams and fracture coatings.
