Feature extraction of geological signatures by multiscale gravimetry

摘要

In this paper we are especially concerned with new potential methods in exploration, useful particularly in geothermal research. Based on a physically relevant regularizing approach involving the Newtonian volume integral, we mathematically investigate the extractable information of the Earth’s gravitational potential obtained by gravimetry for both gravitational potential modeling and geological density interpretation. More explicitly, gravimetric data sets are exploited to extract and visualize geological features inherently available in signature bands of certain geological formations such as aquifers, salt domes etc.
