Uravan Mineral Belt
The Uravan District is a sublocality of the much larger Uravan Mineral Belt. The District was an important uranium-vanadium producing area. Dunn summarizes the District:
The town site of Uravan is now a Superfund site. It was a company town established by the U.S. Vanadium Corporation in 1936 to extract the rich vanadium ore in the region. As a by-product of vanadium extraction, small amounts of uranium were also produced, at the time mostly used as a yellow pigment (Wikipedia).
Environmental clean-up of the site commenced in 1986 and was essentially completed by 2001. All the buildings have been removed, and the site regraded and replanted (Wikipedia).
Area centered around the junction of the San Miguel and Dolores rivers, in Mesa, Montrose, and San Miguel counties. Encompassed by the Uravan mineral belt; includes the Rock (Roc) Creek district (Montrose County) and the McIntyre district (San Miguel County); may overlap the Gateway district to the N. Most of the uranium produced in Colorado comes from this district. "Uravan" is a combination of the words uranium and vanadium, extracted from the carnotite ores. The area was unsuccessfully prospected for other minerals before carnotite ore was shipped from the Rock Creek claim in 1898. The Joe Junior Camp was developed by the US Vanadium Corporation and renamed Uravan. The General Vanadium Company and others became active in the district starting in ~1910, expanding carnotite mining. Production activity was expanded further with World War II. The district includes the Yellow Bird, Thunderbold, and Long Park claims.
The name "Uravan mineral belt" is applied to a narrow, elongate area in southwestern Colorado in which carnotite deposits in the Morrison formation have a closer spacing, larger size, and higher grade than those in adjoining areas.
The belt extends from Gateway through Uravan to Slick Rock. The deposits within the belt tend to be clustered in patches of favorable ground 1,000 ft or more in width and usually a mile or more in length. These patches of favorable ground, and the deposits within them, generally are elongate normal to the trend of the mineral belt. Similarly the fossil logs and the ore rolls within the deposits have a dominant orientation normal to the belt. The mineral belt probably was localized by geologic conditions extant during the time the ore-bearing Morrison formation was deposited.
