Alkalic rocks and resources of thorium and associated elements in the Powderhorn District, Gunnison County, Colorado
J. C. Olson, D. C. Hedlund
1981, Professional Paper 1049-C
Alkalic igneous rocks and related concentrations of thorium, niobium, rare-earth elements, titanium, and other elements have long been known in the Powderhorn mining district and have been explored intermittently for several decades. The deposits formed chiefly about 570 m.y. (million years) ago in latest Precambrian or Early Cambrian time. They...
