AREAS OF EXPERTISE
(Contact whgeol@gmail.com for more information on Whitehall Geogroup, Inc.'s services.)
PALEOSOL INTERPRETATIONS - A primary focus of WGI's research is paleosol identification in continental strata. WGI's current research is focused on calcic paleosols, particularly calcic pedocomplexes.
CONTINENTAL SEDIMENTATION/STRATIGRAPHIC ANALYSIS - WGI research is directed towards the delineation of continental sedimentation patterns by various geological/geophysical techniques, and the development of sequence stratigraphic techniques as applied to continental deposits.
GEOLOGIC MAPPING - WGI specializes in geologic mapping of Cenozoic basin fill in the western United States. We have also recently completed numerous 1:24,000 scale geologic maps for geologic baseline studies of properties throughout western and central Montana. Some of our recent projects in Montana include:
Toston-Townsend area- WGI has compiled a geologic map of the Toston-Townsend valleys, southwestern Montana. This map includes the Sixmile Creek type section, and is available at the 1:100,000 scale (metric topographic). WGI is continuing geologic mapping in this area. Our emphasis is on mapping the stratigraphy/structure of Cenozoic deposits.
Rocker-Ramsey area - WGI has recently completed a geologic map of the Rocker - Ramsey area, southwestern Montana. This map is available at the 1:100,000 scale (metric topographic), and covers part of the upper Clark Fork Superfund area.
Sage Creek - Upper Ruby - Blacktail Valleys, Montana WGI has completed a geologic map of the Sage Creek - Upper Ruby - Blacktail valleys, southwestern Montana. This map is available at the 1:100,000 scale (metric topographic). A report accompanies this map; the report includes unpublished age dates (radiometric/vertebrate land mammal ages) and lithologic descriptions of the Cenozoic strata.
GIS EARTH SCIENCE APPLICATIONS - A recent WGI project is the compilation of vertebrate fossil sites and their associated fossil assemblages found on public lands within Beaverhead and Madison counties, Montana. The fossil site compilation is in ArcView 3.2 format, and was completed for the Bureau of Land Management Dillon Resource Office in Dillon, Montana. Project components include several 100k land grids, associated 100k land ownership grids, and fossil assemblage/ general collection database files. Contact us at: whgeol@gmail.com for further information on this project.
HIGH RESOLUTION SEISMIC REFLECTION/ REFRACTION DATA ACQUISITION AND INTERPRETATION - WGI performs shallow seismic data acquisition/interpretation. Our work in this area has been focused on developing acquisition parameters and interpretation techniques for Cenozoic continental basin-fill.
GEOLOGICAL REVIEW OF REAL ESTATE PROPERTY - WGI provides field work and report summaries of properties in southwestern Montana for private parties in order to meet due diligence and county planning regulations.
CONSERVATION EASEMENT MINERAL REMOTENESS EVALUATION - WGI offers field work and report preparation services for mineral remoteness evaluations. We have completed over 150 evaluations of Montana properties for various conservation organizations and private parties.
VIRTUAL GEOLOGY FIELDTRIPS - WGI is currently developing virtual geological field trips in a multimedia cd-rom format. Our first field trip encompasses the Whitehall, Montana area. Link here to read about the Whitehall area fieldtrip. Our second virtual field trip is on Southwestern Montana Geology.
