Records of wells drilled for oil and gas in New Mexico
G. H. Dixon, D.H. Baltz, T.F. Stipp, R.A. Bieberman
1954, Circular 333
Data concerning nearly 3,000 of the more than 13,000 wells drilled in New Mexico, before September 1, 1953, including unsuccessful wildcat and field extension wells and most of the discovery wells, have been compiled and are published in this circular. Although the search for oil and gas has extended to...
Beryllium resources of the tin-spodumene belt, North Carolina
Wallace R. Griffitts
1954, Circular 309
Pegmatite dikes in the tin-spodumene belt of North and South Carolina uniformly contain about 0.05 percent BeO. The most abundant minerals in the pegmatite contain from 0. 0001 to 0.01 percent BeO. Beryl, having 12.0 to 12.3 percent BeO, is the only beryllium-rich mineral and contains more than 80 percent...
Localization of uranium minerals in channel sediments at the base of the Shinarump conglomerate, Monument Valley, Arizona
I. J. Witkind
1954, Trace Elements Investigations 340
During the summers of 1951 and 1952 the U.S. Geological Survey mapped the geology and uranium deposits in three 15-minute quadrangles on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona. Exposed sedimentary rocks range in age from the Halgaito tongue of the Cutler formation (Permian) to the Salt Wash...
Thorium and rare earth minerals in the Powderhorn district, Gunnison County, Colorado
Jerry C. Olson, Stewart R. Wallace
1954, Trace Elements Investigations 353
Thorium has been found since 1949 in at least 33 deposits in an area 6 miles wide and 20 miles long in the Powderhorn district, Gunnison County, Colo. The district is composed largely of pre-Jurassic metamorphic and igneous rocks, which are chiefly if not entirely pre-Cambrian in age. The metamorphic...
The quality and character of Pacific Northwest waters
Herbert A. Swenson
1954, Report
This paper is a general discussion of the quality and chemical character of surface and ground waters in the Pacific Northwest as shown by the available data. Previous quality of water studies reported in the literature are reviewed. The composition of natural waters is considered as to the source and...
Germanium and uranium in coalified wood from Upper Devonian black shale
Irving A. Breger, James M. Schopf
1954, Trace Elements Investigations 496
Microscopic study of black, vitreous, carbonaceous material occurring in the Chattanooga shale in Tennessee and in the Cleveland member of the Ohio shale in Ohio has revealed coalified woody plant tissue. Some samples have shown sufficient detail to be identified with the genus Callixylon. Similar material has been reported in...
Radioactive deposits in California
George W. Walker, Tom G. Lovering
1954, Trace Elements Investigations 229
Reconnaissance examination by Government geologists of many areas, mine properties, and prospects in California during the period between 1948 and 1953 has confirmed the presence of radioactive materials in place at more than 40 localities. Abnormal radioactivity at these localities is due to concentrations of primary and secondary uranium minerals,...
