Abstract
Metal Mineralization at the Laney Shale Member/Bridger Formation Boundary, Green River Basin, Wyoming
Abstract
In the north-central part of the Green River Basin, near Farson, Wyoming, a surface gold anomaly was reported by the NURE (National Uranium Resource Evaluation) program in 1980. Geochemical sampling has confirmed the presence of a gold anomaly and established that cobalt, nickel, and possibly silver anomalies exist in the same area. The angularity and pristine nature of the gold preclude stream transport as the genetic mechanism (cobalt, nickel, and silver are not normally concentrated by that process either). Black trona brines, found in oil shale in the subsurface of this area, contain a similar suite of metals, are geopressured, and are extremely organic rich. A low-temperature geochemical model is proposed to describe a genetic pathway that links the black trona brines with the metal anomalies.
