Joint gravity and isostatic analysis for basement studies - A novel tool
We have created a working tool – named Lithoflex- that is useful for the interpretation of gravity data in oceanic and continental areas. The tool combines gravity forward and inverse calculation with an investigation of the isostatic state. Density models derived from the gravity field are ambiguou...
