The Nevada Bureau of Mines and Geology (NBMG) Mining District Files (also known as NVGEODEX) is a collection containing over 30,000 items consisting of about 150,000 pages of correspondence, reports, maps, assays, datasets, photographs, newspaper clippings, journal articles, company reports, and government publications. The media is paper, linen, vellum, mylar, cardboard, microfilm and fiche, and photographic paper. This database is the electronic index of the entire collection. Most of the items were scanned as TIFs and converted to PDFs for internet availability. Access is through the NBMG main website at http://www.nbmg.unr.edu, followed by clicking on 1). “Minerals & Energy”, 2). “Mining”, and 3). "Nevada Mining...

This inventory describes photos taken by A. L. Flagg during his travels as a mining engineer over the period 1905 to 1955 and they capture life in developing western North America. The photographs were largely identified using notes made by A.L. Flagg, research of Arizona Department of Mines and Mineral Resources' (ADMMR) mine files and mining periodicals of the time. Principle photograph locations are in Arizona, Colorado, Idaho, Rhode Island, and Washington along with Durango and Oaxaca, Mexico. Arthur Leonard Flagg was born June 29, 1883, the son of Charles Welford and Anna R. (Daley) Flagg. He earned his bachelor’s degree in geology at Brown University in 1906. As a young mining engineer Arthur Flagg followed...

The West Oatman Project collection consists of 92 folders of information on mineral investigations in the western part of the Oatman Metallic Mineral District, Mohave County. The principal mines or groups investigated were the Black Wonder, Moss, AL, ALX, RAL, and FB claims. The folders contain geological and geochemical reports, maps, drill results and related materials.
Subset of rock cores and cuttings held by the West Virginia Geological and Economic Survey (WVGES) that have been inventoried and have had bar codes added to individual boxes. Bar codes indicate individual footage in each box.

The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

Static metadata (current to August 2018) of Minnesota's borehole geophysical log collection maintained by the Minnesota Geological Survey. This collection is web-accessible through the MGS Open Data Portal at http://z.umn.edu/borehole_geo, where users can obtain the most up-to-date information pertaining to old and new borehole geophysical logs and download corresponding PDF and LAS files for each log (if available). The Borehole Geophysical Database (BGD) is a collection of over 7000 borehole geophysical logs of water wells and drill holes throughout Minnesota. Database collections reside at the Minnesota Geological Survey (MGS) and are continually maintained and expanded upon by MGS staff as part of MGS mapping...
