Geophysical maps provide insight into an area’s geology by illuminating features and subsurface characteristics not apparent from a geologic map alone. They are particularly useful in regions where there are limited bedrock outcrops to study. Data collected from geophysical surveys are used to create maps showing the variability in physical properties of different rock types including density, thermal attributes, seismic velocity, magnetic susceptibility, and other electromagnetic parameters.
From geophysical maps and data we can derive one-dimensional (1D), 2D, 3D, and even 4D (time being the fourth dimension) computer models of the corresponding physical properties of the rock types and other materials. Geophysical maps are used in geologic mapping, energy and mineral resource exploration, geothermal exploration, and groundwater monitoring. Types of geophysical maps include gravity, magnetic, seismic, and heat flow.
