- Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910: Part 1. -- Analyses
- From Significance and value of Analyses of Coal: "The analyses published in this report cover samples of coal collected in many different parts of the country with unusual care by experiences men, in such manner as to make them representative of extensive beds of coal."
- 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."
- Flood of July 17, 1972 in Gallup, New Mexico
- From introduction: The purpose of this report is to supplement, in a ore detailed form, data of stage and discharge published in the annual surface-water records of the U.S. Geological Survey. This report includes: description of the flood, information on flood damage, and flood-frequency data.
- Geochemistry of Mariano Lake-Lake Valley Cores, McKinley County, New Mexico
- From abstract: The primary goal of the U.S. Geological Survey-Bureau of Indian Affairs drilling project in the Upper Jurassic Morrison Formation in McKinley County, New Mexico, was to better understand the relationship between host-rock stratigraphy and uranium mineralization. As part of this project, geochemical studies of approximately 280 samples from 8 cores and 1 outcrop were undertaken; samples from 4 of the cores show uranium enrichment. Geochemical relationships between samples of weathered outcrop, oxidized core, reduced (unmineralized) core, and ore-bearing core were contrasted by comparison of element abundances.
- Geologic Reconnaissance of the Southwest Flank of the Zuni Uplift, New Mexico
- Results of a survey in the southwest segment of the Zuni Uplift sedimentary formations. It includes an overview of physical geography in the area, as well as economic geography, including mineral deposits.
- Geologic Reconnaissance of the Southwest Flank of the Zuni Uplift, New Mexico
- Report presenting the results of a survey in the southwest segment of the Zuni Uplift sedimentary formations. The report includes figures and plates that provide an overview of physical geography in the area, as well as economic geography, including mineral deposits.
- Geologic Report on East Chaco Canyon Drilling Project, McKinley and San Juan Counties, New Mexico
- This following report discusses the studies and findings of the East Chaco Canyon drilling project of northwestern New Mexico. These studies took place between July and November of 1978.
- Geophysical Observations in Parts of the Grants District, Mckinley County, New Mexico
- Report discussing geophysical observations in parts of the Grants district of McKinley County, New Mexico. This study had the "dual objective of investigating the unusual occurrence of negative aeromagnetic anomalies in close association with airborne radioactivity anomalies, and of investigating other geophysical methods which might assist directly or indirectly in the search for uranium ores in the Grants district."
- Preliminary Report on the Results of Geobotanical Prospecting on the South Flank of Haystack Butte, McKinley County, New Mexico
- Abstract: The absorber plant method of geobotanical prospecting was tested systematically over the bench formed by the Jurassic Todilto limestone on the south flank of Haystack Butte, McKinley County, N. Mex. This portion of the bench includes the largest known uranium ore body in limestone and most has been extensively drilled by private enterprise. Geobotanical prospecting was accomplished to provide control data. Comparison of the geobotanical anomalies with the available drill hole information from the mining companies and Atomic Energy Commission geologists have shown that the known ore occurrences would have been outlined by the results of the tree sampling. In addition some geobotanical anomalies are indicated in drilled areas in which ore was not reported and in areas not physically explored at the time of sampling. These anomalies may represent mineralized ground below ore grade or new ore deposits.
- Uranium Occurrences in the Ambrosia Lake Area, McKinley County, New Mexico
- Introduction: The Ambrosia Lake area includes all of T. 14 N., R. 10 W., and portions of adjacent townships in McKinley County, approximately 20 miles north of Grants, New Mexico (fig. 1). Uranium was discovered in April, 1955, and extensive exploration drilling followed.
- Uranium occurrences on secs. 4, 8 and 9 T. 12 N, R. 9W, McKinley County, New Mexico
- Discussing information assembled concerning the uranium occurrences within the Todilto limestone, in preparation for proposed ABC exploration in the Grants District
