Add to ORKGThe Twist Gulch Formation and the Morrison (?) Formation were studied as possible future sources of economic concentrations of copper, lead, zinc and silver. The content of these metals was determined by atomic absorption spectrophotometry. The results of this study show that the area studied was depleted from silver and that the concentrations of copper, lead and zinc are not of economic proportions.No embarg
