Discussing fluorimetric uranium analyses and semiquantitative emission spectroscopy on rock samples

Uranium deposits in the precambrian quartz-pebble deposits of the Raft River area in northwestern Utah and southcentral Idaho are examined. A total of 1214 geochemical samples were acquired for the study, particularly 334 water samples, 616 stream sediment samples, and 264 rocks.

Reports providing data for 11 uranium occurrences in the Clinton Quadrangle, including description, uranium analysis, exact location, deposit type, and features of the host rock.

From Introduction: "The Richfield 1º x 2º Quadrangle, Utah, was evaluated to identify and delineate areas and geologic areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. A favorable area or environment, according to the specifications used in this study, is one that is known or is likely to have uranium deposits containing a minimum of 100 tons of U3O8 with an average grade of not less than 100 ppm U3O8."

The Delta 1°x2° Quadrangle, Utah contains rocks which range in age from the Precambrian through the Holocene. It lies in the eastern part of the Basin and Range Province, approximately 85 mi southwest of Salt Lake City. Most known uranium resource potential lies in four geographic environments in two geographic areas. Favorable environments are: (1) Tertiary tuffaceous sandstone and conglomerate epigenetic disseminated deposits; (2) volcanic hydroallogenic environments containing uranium-mineralized altered tephra in the beryllium tuff member of the Miocene Spor Mountain Formation; (3) pipes or small diatreme structures in the Paleozoic limestones and quartzites on Spor Mountain, defined as Tertiary volcanogenic hydroallogenic environments; and, (4) alluvial-lacustrine placer environments, on the east and west sides of the Deep Creek Range adjacent to the quartz monzonite Ibapah stock. The significant volume of Miocene rhyolites and tuffs in the Quadrangle contain uncommonly large abundances of uranium and thorium.

From Introduction: "The Price 1ºx2º Quadrangle, in central Utah, (Fig. 1) was studied to identify and evaluate and geologic formations that are favorable for the areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Introduction: "The Cortez 1º x 2º Quadrangle, southwestern Colorado and southeastern Utah (Fig. 1), was studied to identify and evaluate areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Introduction: "The Moab 1ºX2º Quadrangle, east-central Utah and west-central Colorado (Fig. 1) was studied to identify and evaluate areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

The purpose of this report is to summarize the information obtained by the project, to make geologic interpretations of the information, and to transmit the information and interpretations of the information to the U.S. Department of Energy and the Geology Division of Bendix Field Engineering Corporation, Grand Junction Colorado.

Logs describing lithologic characteristics of samples collected from the project area described using a binocular microscope or hand lens and recorded on standard Bendix Field Engineering Corporation (BFEC) logging forms.

From Purpose and Scope of Study: "The purpose of this study is to provide an evaluation of the favorability of the Vernal, Colorado-Utah, 1º x 2º Quadrangle (Fig. 1) for the occurrence of uranium deposits. The study restricted to indicating geologic units and areas favorable for uranium deposits containing at least 100 tons of U3O8 with an average grade of .01 percent U3O8 or more and less than 1,500m (5,000 ft) deep."

From Introduction: "The purpose of this study is to provide an evaluation of the favorability of the Craig 1º x 2º Quanrangle, Colorado (Fig. 1) for the occurrence of uranium deposits."

Discussing statistical analyses of the Lewiston Quadrangle

From Introduction: "The Front Range region from the Wyoming-Colorado state line to southern Colorado is a uranium metallogenic province. Correspondingly, uranium has been discovered in mineable deposits in metamorphic, igneous, and sedimentary rocks formed throughout the geologic history of the region both within the Front Range itself and in the apron of sedimentary rocks that surrounds the Front Range. The Pueblo 1ºx2º National Topographic Map Series (NTMS) quadrangle, Colorado (Fig. 1), which lies within this uranium metallogenic providence, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."
