Geology of Carnotite-Bearing Sandstone in the Uravan and Gateway Districts, Montrose and Mesa Counties, Colorado, and Grand County, Utah (open access)

Geology of Carnotite-Bearing Sandstone in the Uravan and Gateway Districts, Montrose and Mesa Counties, Colorado, and Grand County, Utah

From Introduction: "In the Uravan and Gateway districts, the general character of the bedding in the ore-bearing sandstone and amount of alteration in associated mudstones, and the relation of these to each other, are the features most useful as large-scale guides. This report describes these features and their distribution, as well as some other significant geologic characteristics of the ore-bearing sandstone."

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples (open access)

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

A Review of the Physical and Engineering Properties of Raw and Retorted Oil Shales from the Green River Formation: Final Report (open access)

A Review of the Physical and Engineering Properties of Raw and Retorted Oil Shales from the Green River Formation: Final Report

"This report summarizes published geotechnical properties of raw and retorted oil shales from the Green River Formation. Basic physical properties including gradation, specific gravity and Atterberg limits and engineering properties including compaction, permeability, settlement, soundness, and strength are summarized and discussed. Where appropriate, conclusions are drawn about the suitability of retorted oil shales as a geotechnical construction material. Appendix A discusses three retorting processes used to extract oil from oil shale" (abstract, para. 2-3).
