Uranium Deposits Navajo Nation
Ore deposits have formed at various periods over geological time from at least 3500 million years ago to the present day where mineral deposits are forming as part of natural earth processes both on land and on the sea-floor. Deposits have commonly formed through a combination of geological factors closely related in time. Advances in the dating of geological processes have shown that many ore... Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. Ore-genesis theories generally involve three components: source, transport or conduit, and trap.
