At a scale of 1:100,000, this map shows an uncommon level of detail for State geologic maps. Mapped rock units are primarily based on lithology, or rock type, to facilitate derivative studies in multiple disciplines.
Report of research on the Carolina slate belt and gold deposits in Virginia, North Carolina, South Carolina, and Georgia with geologic mapping, mineralogic, geochemical, and fluid evolution studies, radiogenic dating, and stable isotope studies.
Rocks representing a variety of tectonic and depositional environments outcrop along the canal and towpath and reveal the geologic history of the central Appalachian region from the Mesoproterozoic to Jurassic Period.
This digital map database represents the general distribution of the geology (bedrock and surficial deposits) in San Mateo County. Accompanying text file (*.txt or *.ps) provides current information on the geologic structure and stratigraphy.
Coordinated studies of the effect of historical mining for mercury, origin and composition of metals in groundwaters and surface waters, history of volcanic and intrusive activity, and the complex geological history of this area.
Techniques of computer-based representations of areal geology to construct three-dimensional geologic maps that retain all the information of traditional geologic maps while providing a more detailed picture of the subsurface.
Overview of research to measure, predict, and understand the flow of water through soil and rock between the land surface and the water table with links to field sites, laboratory methods, theoretical developments, publications, and personnel.
Homepage for project on Bear Lake, Idaho-Utah, to study past climate change and effect on lake catchment basins. Includes link to summary, personnel, geology, methods used including coring and seismic surveying, and publications.
