Gravity methods measure the change in the earth’s gravitational field caused by variations in the density of the subsurface. Gravity surveys can be used to detect and map buried structures such as faults, voids, bedrock topography, and basin geometry. The data can be processed to determine the size, depth, shape, and composition of various targets.
Typical Applications of Gravity Methods
- Karst features
- Voids and tunnels
- Bedrock valleys and paleo channels
- Faults and other geologic structure
- Basin geometry
- Petroleum exploration
- Natural resources exploration
