Lithology of Russia, from the Land Resources of Russia collection. The attribute displayed is the dominant parent rock for the polygon. Full description of this dataset can be found at http://www.iiasa.ac.at/Research/FOR/russia_cd/litho.htm .

As part of a research study in cooperation with the U.S. Environmental Protection Agency (EPA) and the U.S. Army at Fort Irwin National Training Center, the U.S. Geological Survey (USGS) evaluated unsaturated zone soil property data of cores from a borehole for a newly drilled monitoring well near a dry well and Four-plex baseball field. Cores were continuous from land surface down to 240 feet below land surface and were drilled by consultants to EPA using sonic rotary–a fluidless drilling technique. Data on this page consist of: 1) field drilling notes from USGS and consultants to EPA (GeoSystems Analysis, Inc., Tucson, Arizona); 2) field descriptions of core lithology–including grain size, sorting, color, mineralogy,...

These digital maps are a reformulation of previously published maps, primarily maps of states. The reformulation gives all the maps the same structure and format, allowing them to be combined into regional maps. The associated data tables have information about age and lithology of the map units, also in a standard format.

This geospatially explicit vector-based polygon dataset identifies 85 terrestrial ecological subsection delineations present in Southeast Alaska and the Tongass National Forest. Within each subsection one can expect to find a relatively consistent occurence and distribution of vegetation types. Due to the hydrologically-influenced geomorphology of Southeast Alaska specific key indicators of physiography, lithology, and surface geology were employed to systematically distinguish terrestrial ecosystems.
Dataset contains digital versions of physical core logs housed in Missouri Geological Survey archives. The logs are variable in detail, ranging from simple locations and formation tops to extensive stratigraphic descriptions and chemistry. A portion were done by MGS staff; others were donated by industry, academia, and government entities. The dataset includes logs for mines or undeveloped deposits with occurrences of or potential for critical minerals, along with logs in areas with permissive geology. The dataset comprises three tables: header and location information; formation/stratigraphic top, bottom and written description; and geochemical and assay data.
