This dataset is a collection of unpublished geologic field maps and transfer maps that represent over 100 years of field data collected by Virginia geological survey staff. These field records include hand-drawn notes, strike and dip, contacts, economic, structure and paleo information. Some maps have been scanned and are available digitally. Most maps are located in our Charlottesville, Va offices in paper format. All are unique, one-of-a-kind documents.

The Coal Quality Data Collection includes results of laboratory analysis for 375 coal samples collected as part of a cooperative sampling program between DGMR and the U.S. Geological Survey (USGS). The samples were collected by DGMR staff during the period from 1975 to 1988 from a six county area in the Southwest Virginia Coalfield. A total of 38 coal beds are represented in the sampling program. For each sample location there are laboratory results for Proximate and Ultimate analysis, ash-fusion temperatures, and major- and minor- element analyses.

The Historic Topographic Maps Collection consists of compiled and digitally rendered two series of topographic maps for Virginia. Historical topographic maps can be useful resources for those interested in researching the changes in a particular area over time. Maps of different ages can also illustrate how development has occurred in a location. These map series were produced by the United States Geological Survey in cooperation with the Commonwealth of Virginia. They are in 15-minute and 30-minute quadrangle format, respectively, and range in age from 1884 to 1962. Detailed map explanations for each series have been scanned separately. PDF indexes have also been created to make maps of interest easier to locate....

The Division of Geology and Mineral Resources (DGMR) Publications Index consists of a database with information on DGMR's Geologic Publications. This includes all formal publications as well as bulletins, information circulars, mineral resource circulars, open file reports, report of investigations and mineral resources reports. The index will provide basic information such as title, author, abstract and a link to the DMME Web Store where customer can purchase hard copies or download copies for free.

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. ...
