From introduction: The compilation of the tectonic map of northern Colorado and northeastern Utah (area h, fig. 2) was done by the U. S. Geological Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. Structures shown on the map have been obtained from published geologic maps, and from unpublished data supplied by government agencies, private companies, and independent geologists. The various structures of the Foreland can be divided into three large classes to show the relation of uranium deposits to the structural pattern.

From introduction: The Martha E prospect, in Spring Gulch about three and one-half miles southwest of Idaho Springs, Colo. (fig. 1), is on a claim, originally called the Daisy Freese, which was first prospected by the Stanley Mines. The occurrence of radioactive minerals in the adit was called to the attention of the U. S. Geological Survey in 1950 by the owners of the claim. The Survey's Trace Elements Section Washington Laboratory identified metatorbernite, autunite, and sooty pitchblende.

From abstract: The distribution of the known uranium deposits of the Colorado Plateau is being analyzed in order 1) to test for systematic relationships between that pattern and geologic factors, 2) to help guide exploration, and 3) to appraise the potential resources of the region and of each of its component areas.

The quadrangle includes portions of the Colorado Plateau and southern Rocky Mountains Physiographic Provinces. The entire area of the Gunnison Uplift and parts of the Uncompahgre and Sawatch Uplifts are included. A part of the Piceance Basin and a segment of the Rio Grande Rift Valley are also included. A basement complex of Precambrian metamorphic and igneous rocks is exposed in the core of the Gunnison and Sawatch Uplifts in the Southern Rocky Mountains. Jurassic and Cretaceous age sedimentary rocks lie directly on the Precambrian basement in most places. They lie on Paleozoic rocks at the west edge of the Sawatch Uplift in the north-central part of the quadrangle. Triassic beds are mapped only in the canyon of the Uncompahgre River near the southwest corner of the quadrangle. A suite of Tertiary volcanics and some sedimentary rocks occupy extensive areas. Plutonic rocks of Tertiary and laramide age occupy only a small part of the quadrangle. The literature consulted included information on about 100 separate occurrences of radioactive minerals and/or anomalous radioactivity within the quadrangle. Many fracture and stratigraphically controlled forms are reported. Most of these occurrences are clustered in three areas: Cochetopa Creek, Cebolla Creek, and Marshall Pass. Important uranium …

From abstract: An investigation of the use of geophysical methods in prospecting for carnotite deposits in the Colorado Plateau was made by the Geophysics Branch of the U. S. Geological Survey between April 21 and June 24, 1949. Results of this preliminary work indicated that electrical resistivity methods could be used successfully.

Assignment of the vibrational modes Of Os{sub 2}(CO){sub 8}(CHCH{sub 3}) and Os(CO){sub 4}(C{sub 2}H{sub 4)} has given fingerprint vibrational spectra for the following species when chemisorbed on metal catalyst surfaces: ethylidene and ethylene bound in a metallacyclopropane mode. The formation and fragmentation of diosmacyclobutanes have been shown to involve slippage of the outgoing olefin onto a single osmium, and associative exchange of the olefin from that site. The incorporation of vinylcyclopropane without rearrangement has confirmed the absence of a diradical intermediate. The anomalous stability of the diosmacyclobutane derived from trans-2-butene has proven due to greater destabilization (by the substituent methyls) of the slipped intermediate than of the ground state. Reaction of an osmacyclobutane with 1,3- or 1,2-dienes (allenes) gives 1,2 rather than 1,4 addition to the diosmium unit. Treatment of Os(CO){sub 4}(C{sub 2}H{sub 4}) with triflic acid results in the formation of Os(CO){sub 4}(C{sub 2}H{sub 5})OTf. The authors have found that the reaction of an aryl iodine(III) reagent with propargyl stannanes or silanes results in o-iodo propargyl arenes.

This report evaluates potential impacts to public health or the environment resulting from groundwater contamination at the former uranium mill processing site. The tailings and other contaminated material at this site are being placed in an off-site disposal cell by the US Department of Energy`s (DOE) Uranium Mill Tailings Remedial Action (UMTRA) Project. Currently, the UMTRA Project is evaluating groundwater contamination. This is the second risk assessment of groundwater contamination at this site. The first risk assessment was performed primarily to evaluate existing domestic wells to determine the potential for immediate human health and environmental impacts. This risk assessment evaluates the most contaminated groundwater that flows beneath the processing site towards the Gunnison River. The monitor wells that have consistently shown the highest concentration of most contaminants are used in this risk assessment. This risk assessment will be used in conjunction with additional activities and documents to assist in determining what remedial action is needed for contaminated groundwater at the site after the tailings are relocated. This risk assessment follows an approach outlined by the US Environmental Protection Agency (EPA). The first step is to evaluate groundwater data collected from monitor wells at the site. Evaluation of these data showed …

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.

Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …
