Surveys by GeoModel, Inc.

GeoModel, Inc. has a staff of Professional Geologists to conduct geologic mapping at any site. All GeoModel, Inc. geologists have Master's Degrees in Geology and have conducted geologic mapping worldwide. GeoModel, Inc. uses its staff of geologists along with its geophysical equipment to obtain a complete understanding of a site's geologic history.

GeoModel, Inc. conducts geological mapping using electromagnetic conductivity (EM) surveys and ground penetrating radar (GPR) surveys as well as conducting field observations. The types of geological features that can be studied include:

• Buried Channels
• Bedrock Profiles
• Geologic Faults
• Rock Units
• Soil Layers

Electromagnetic Conductivity (EM)

Electromagnetic conductivity measures the conductivity of the subsurface. This measurement includes the conductivity of soil, groundwater, and rock. GeoModel, Inc. has conducted numerous electromagnetic conductivity (EM) surveys worldwide.

Electromagnetic conductivity surveys are rapid and very accurate. The EM instruments are easily carried and can easily determine variations in ground conductivity that can indicate changes from materials of low conductivity (sand or granite for example) and materials of high conductivity (clay or shale deposits).

GeoModel, Inc.'s geophysicists can perform an EM survey anywhere in the world and with short notice. Survey costs are reasonable.

Ground Penetrating Radar (GPR)

Ground penetrating radar (GPR) produces an underground cross-sectional image of the subsurface soil and rock. Depths up to 100 feet (30 meters) or more can be examined. GeoModel, Inc. conducts surveys using a SIR-2 digital control unit and various antennas with frequencies ranging from 25 to 1,000 MHz.

At geological mapping sites, GPR can locate buried stream channels, obtain bedrock profiles, and get cross-sectional images of soil layers.
