Gravity and Magnetic Interpretation

To ensure the most accurate gravity and magnetic data interpretation, a structural surface is computed using a three-dimensional solution for gravity data. The process begins with the construction of a Regional Gravity Map, which represents the gravity response to the density changes within the basement. This is then subtracted from the Bouguer gravity field to separate the residual gravity anomalies. Any pertinent information such as residual or derivative data, density contrast information, and the reference base for the geometric models are then entered into our computer program. The result is a residual grid that establishes a corresponding network of vertical prisms with a variable height on a reference surface. The output of the program includes the height of the prisms or structural surface whose computed gravity response matches the input gravity. The data can be contoured in feet or in meters.
