Violarite from the Copper King mine, Boulder County, Colo., occurs as a secondary mineral after pentlandite. It is associated with fresh pyrrhotite and with several altered forms of pyrrhotite including secondary pyrite after pyrrhotite. Hence violarite has a much broader stability range in the oxid

Vein-type uranium deposits of geologic interest and commercial significance occur in the Cochetopa mining district, Saguache and Gunnison Counties, Colorado. The uranium minerals in these deposits have been precipitated from hypogene solutions probably related to Tertiary igneous activity in the dis

Radioactive age determinations have been made on 16 minerals from the Brown Derby pegmatite and the Quartz Creek granite. A high degree of consistency has been found among the Rb-Sr ages measured on micas and feldspars. A similar degree of consistency exists in the K-A ages of micas. These consisten

The story of the advancing American frontier has unending interest. Perhaps one of the most colorful and unusual frontier developments was that of the mining frontier in the Rocky Mountains of Colorado. During the years following the discovery of gold in 1858 and the early 1880's occurred an almost

The Dunmore lode is localized along a persistent fissure zone over two miles long and averaging nearly 100 feet in width along the length of the Dunmore claim. The fault in which the lode is located offset the pre-Cambrian quartzite and slate walls about 4,500 feet prior to deposition of the overlyi

In previous reports on the Cretaceous rocks of NM, writers have followed the nomenclature established by Cross, and have described all the rocks between the Dakota Sandstone and the Mesaverde coal measures as Mancos Shale. Lee and Darton, in describing the rocks of central and northeastern NM, recog
