Abstract
Oligocene Gold-Bearing Conglomerate, Southeast Margin of Wind River Mountains, Wyoming
Abstract
Gold-bearing conglomerates of Oligocene age were deposited as a giant alluvial fan by the ancestral Twin Creek where it emerged from the Wind River Mountains and flowed eastward and northeastward into the Wind River Basin. During Quarternary time, gold from these gravels was concentrated in alluvium along several modern stream valleys. Our studies suggest that the gold source area has not been discovered because it was covered in later Oligocene time by windborne ash and tuffaceous claystone deposits that aggregated to at least 400 feet in thickness. It would be beneath these deposits in a 4-square-mile area approximately 2 to 4 miles north and northwest of Miners Delight — a now-abandoned gold-mining area.
