Report issued by the Bureau of Mines over petroleum engineering studies conducted in Texas and New Mexico. The results of the studies are presented and discussed. This report includes tables, maps, illustrations, and photographs.

Report issued by the U.S. Bureau of Mines discussing the annual report over the research and technology of coal during 1941. As stated in the foreword, "these investigations increase our fund of exact knowledge on the properties and composition of American coals and lead to better methods in mining, preparing, storing, and utilizing coal" (p. 4). This report includes tables, illustrations, photographs, and a map.

Report issued by the U.S. Bureau of Mines on experiments conducted regarding the desulfurization of distillates from crude oil. Characteristics and desulfurization processes are presented. This report includes tables, and a chart.

From abstract: The Merry Widow claim is near the center of sec. 22, T. 20 S., R, 15 W, New Mexico principal meridian, about 1 mile west of White Signal, Grant County, N. Mex. Secondary uranium minerals were discovered in the White Signal district in the early 1920's although several mines in the district had been worked previously for gold, silver, and copper. The writers mapped the Merry Widow claim in 1950, collected 133 samples, and logged the core from one diamond-drill hole on the Merry Widow claim.

Report discussing the investigation of the chemical composition of sandstone-type uranium ores and unmineralized sandstones of the Colorado Plateau. Spectrographic and chemical analyses was used.

Investigating possible structural, mineralogical and volcanic relations between the central core and ore-producing sediments of the northeast flank.

Appendix containing tables to accompany a report on aerial radio radiometric and magnetic reconnaissance survey instrumentation and methods of portions of Arizona and New Mexico.

From introduction: Major objectives of the National Uranium Resource Evaluation (NURE) program, sponsored by the Department of Energy (DOE), are to develop an authoritative, comprehensive assessment of the nation's uranium resources and to provide industry with data and technology useful for the timely discovery and exploitation of uranium ores (ERDA, 1976). The National Aerial Radiometric Reconnaissance Survey is a major element of the NURE program.
