... barite mine. This mine, idle since 1958, has the best exposures of rock pinnacles, remnants of upper Knox Group mineralized breccias. As at all the mines in the Sweetwater district, economic ore occurs only in the clay residuum and mining stops when bedrock is reached. Trip returns to Knoxville. ...

... converted to nodular anhydrite during shallow burial. Regionally the depositional setting can be divided into two areas:(a) a higher energy shoal region in the vicinity of the mine and Cadjebut Fault and (b) a landward more restricted lower energy evaporitic lagoonal setting. Two petrographically distinct...
