Subsurface structural mapping from high-resolution gravity data using advanced processing methods

Subsurface structural mapping from high-resolution gravity data using advanced processing methods

The study area has a complex geological structure and is studied for mapping the density interfaces using geophysical techniques. However, it has not been studied for mapping geological structures, such as contacts and faults that appear as lineaments in gravity data. In this study, the lineaments i...
