About This Publication
This map focuses on mineral resources associated with Tertiary intrusives and volcanic rocks of West Texas. Maps of this region provide a basic geologic framework to aid in managing water and earth resources; planning land use; and identifying sources of rare earth elements, precious and base metals, uranium, thorium, fluorine, beryllium, and other earth resources. This study area covers Tertiary hypabyssal rhyolite laccoliths and volcanic rocks south of the Sierra Blanca peak, and the east side of the Quitman Mountain caldera system, within and overlying Cretaceous Cox sandstone, Finlay and Buda limestone, Etholen conglomerate, and Bluff Mesa limestone stratigraphy. The Tertiary intrusive and volcanic rocks provide excellent potential for hydrothermal mineral resource formation, skarn development, and magmatic ore resources in West Texas.
