Tabulation or Ore Reserves and Past Production for the Uranium-Vanadium Region of Colorado, Utah, New Mexico, and Arizona

The tabulations on these pages include all of the known areas in Colorado, Utah, New Mexico, and Arizona having economically important uranium-vanadium deposits of the type which are generally referred to by the terms roscoe-lite and/or carnotite. Though similar deposits are known to exist in other areas they are to be viewed as being little more than mineralogical curiosities.

Memorandum Listing the Areas in Colorado, Utah, Arizona and New Mexico that are Geologically Favorable for Developing Large Reserves of Vanadium Ore by Prospecting (open access)

Memorandum Listing the Areas in Colorado, Utah, Arizona and New Mexico that are Geologically Favorable for Developing Large Reserves of Vanadium Ore by Prospecting

Introduction: Vanadium ore is being mined at many places in western Colorado, southeastern Utah, northeastern Arizona, and northwestern New Mexico (fig. 1). Eight mills in this region produced about 4,300,000 pounds of V2 05 in 1942, representing about 90 percent of the vanadium obtained from domestic sources. Although ore production has mostly exceeded mill capacity since 1937, production during the last half of 1942 averaged only about 19,000 tons or ore a month, whereas the capacity of these mills total about 22,000 tons a month. At the expected rate of ore production, ore stockpiles will be exhausted sometime in 1944, and these mills will then have excess capacity. With more intensive prospecting than now practiced, however, it is believed that sufficient reserves can be indicated to sustain capacity operation of these mills for several years. This memorandum is prepared to specify those areas that are considered most favorable from a geologic standpoint for developing large reserves of vanadium ore by prospecting. It is based on intensive studies by the Geological Survey since 1939 in most of the areas that produce vanadium ore.

Report on Reserves and Production Situation of Vanadiferous and Related Ores in Colorado Plateau Region

From introduction: The general distribution of known deposits of vanadium-bearing sandstone, which also contain some uranium and radium, is shown in figure 1 1/ and Exhibit A, plate 53. 2/ During 1939-41 the Geological Survey made detailed geological studies of these deposits in the Uravan district, Montrose County, Colorado, as well as preliminary examinations in other parts of the Colorado Plateau vanadium region. In 1942 detailed geological studies were made o the deposits in the Egnar-Slick Rock district, San Miguel Co., Colo.; 3/ the Carrizo Moungains district, Navajo Indian Reservation, Arizona and New Mexico; 4/ the Placerville district, San Miguel County, Colo. 5/ and the Monticello district, San Juan Co., Utah. 6/ Since May 3, 1943, the Gelogical Survey has guided the Bureau of Mines program of prospecting these deposits in parts of Colorado and Utah.

The Distribution of Uranium-Vanadium Deposits in the Colorado Plateau Relative to Tertiary Intrusive Masses (open access)

The Distribution of Uranium-Vanadium Deposits in the Colorado Plateau Relative to Tertiary Intrusive Masses

Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity of the La Sal, Abajo, Carrizo, and Henry mountains. Elsewhere, it is believed that a written description will suffice.

Stratigraphy of the Mississippian System, South-Central Colorado and North-Central New Mexico

From abstract: In the Sawatch, Mosquito and Front Ranges of central Colorado and the Sangre de Cristo Mountains of south-central Colorado, Tournaisian beds of the Mississippian Leadville Limestone overlie rocks of Early Mississippian and Late Devonian age. In the Sangre de Cristo Mountains in north-central New Mexico, the oldest beds are the Tournaisian (zone 9) Espiritu Santo Formation. In west-central New Mexico, in the Magdalena, Lemitar, and Ladron Mountains, the Kelly Limestone of Tournaisian and Visean age rests unconformably on Proterozoic metamorphic and igneous rocks. This report examines the stratigraphy of this area.
