GMRE geologists use a combination of traditional and modern
investigative techniques in conducting field studies. For example, we
perform bedrock mapping using topographic base maps and aerial
photographs, but also use GPS receivers to verify our field stations.
Positional coordinates acquired in UTM, Geographic, or State Planar
systems are then compiled in databases for later use in a GIS or other
applications. We also employ aerial photographs, DOQQ images, and
other remote sensing data when appropriate.
Our primary areas of expertise:
Field Investigations
- Detailed geologic mapping - considerable experience in sedimentary,
igneous, and metamorphic terrains
- Analysis of geologic structures
- Stratigraphic and correlation studies
- Reconnaissance geology (for preliminary assessments or other needs)
- Supervision of diamond drilling operations
- Diamond drill core logging and evaluation
- Due diligence studies and expert testimony
- Slope stability evaluations
- Exploration projects for rare igneous rocks: kimberlites, lamprophyres, and
carbonatites. This work usually includes recovery of kimberlite indicator
minerals (e.g., pyrope, picroilmenite) and mapping of intrusions and
diatremes.
- Evaluation of "Acid Rock" exposures and potential ARD sites. This work
includes:
- Site characterization
- Risk assessments
- Assistance with remediation efforts
Laboratory Investigations
- Petrographic analysis of sedimentary, igneous, and
metamorphic rocks, including transmitted and
reflected light microscopy
- Digital photography of thin-sections
- Whole-rock and mineral chemical analyses: Plotting
and interpreting data in a variety of formats
