Geology and Ore Resources of the Uranium-Vanadium Depositional Province of the Colorado Plateau Region

Description: From introduction and acknowledgements: This report is written to supplement and complete the record contained in some fifty district and special reports already submitted, and duplication of material in district reports has been studiously avoided. The data herein contained are largely of a regional type, inclusion of which was not wholly appropriate to the district reports.

Manganese Deposits in the Artillery Mountains Region, Mohave County, Arizona

Description: From abstract: The manganese deposits of the Artillery Mountains region lie within an area of about 25 square miles between the Artillery and Rawhide Mountains, on the west side of the Bill Williams River in west-central Arizona. The richest croppings are on the northeast side of this area, among the foothills of the Artillery Mountains. They are 6 to 10 miles from Alamo. The nearest shipping points are Congress, about 50 miles to the east, and Aguila, about 50 miles to the southeast. The princ… more

Manganese Resources of the Artillery Mountains Region, Mohave County, Arizona

Description: From introduction: The sampling on which the estimates of ore reserves in this report are partly based was done by Lasky and Roberts. The text was written by Lasky, who, except where otherwise noted, is responsible for any descriptions, comments, and conclusions concerning the area beyond the limits of the Hanna holdings, as well as for all statements concerning reserves and recommendations for future prospecting.

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

Description: 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… more

Regrassing for Soil Protection in the Southwest

Description: "This bulletin is designed to help the stockmen and farmers, of the Southwest [United States] particularly, in reestablishing depleted ranges where unfavorable climatic conditions and heavy demands on the range have served to make improvement of the range by natural means a slow and difficult process. It discusses the latest methods of artificial revegetation that have proved most effective in regrassing the ranges. It also discusses the more promising grasses and indicates that areas to which … more

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

Description: 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… more

Report on SOM Investigations in Arizona (Except the Plateau Province Area)

Description: From summary: Union Mines' examination of Arizona's pegmatites, lode deposits of the central and southeastern parts of the state, and heavy mineral concentrates from few placer deposits indicates that SOM is practically non-existent in the first two and that minor amounts of monazite and possibly other S-37 minerals are present in the last.

Strawberry Culture: Western United States

Description: Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons familiar only with local and perhaps unsatisfactory methods, as well as inexperienced pros… more

Strawberry Culture: Western United States

Description: Revised edition. "Strawberries can be grown in those parts of the western Untied States in which ordinary farm crops are irrigated as well as in western Oregon and Washington, where irrigation is not essential but may be profitable. The principles of irrigating strawberries are essentially the same as those for other crops. Because strawberries are sensitive to the alkali salts that irrigation brings to the surface, such salts must be washed out or skimmed off. The strawberry grower, after choo… more

Supplemental and Summary Report on Western Carrizo Uplift and Chuska Mountains Areas of Northern Navajo Indian Reservation Northeastern Arizona

Description: General purpose of survey: During the period 1943 and 1944, the primary purpose was to locate, describe, sample, and generally evaluate the SOM-vanadium mineralization in the western Carrizo Uplift and Chuska Mountains Areas. To this end, the areal geology of the areas, with emphasis on the Salt Wash member of the Morrison formation, was mapped. The triangulation and the laying out of leased plots were supplemental parts of this work. The field work in 1945 was for the purpose of collecting add… more

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

Description: 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.

Vanadium Deposits in the Carrizo Mountains District, Navajo Indian Reservation, Northeastern Arizona and Northwestern New Mexico

Description: From abstract: The Carrizo Mountains vanadium district is in the Navajo Indian Reservation, northeastern Arizona and northwestern New Mexico. From May through October, 1942, two mining companies, operating under lease agreements with the Navajo Service, opened several mines in the district and produced a total of about 6,000 tons of ore, averaging approximately 2.2 percent.
