Gravity data from the International Gravimetric Bureau and the
Gravimetric Atlas of Switzerland have been used to evaluate their
application and limitations as a subsurface investigation tool to
constrain key geological structures in support of the georesources
exploration in the Geneva Basin (GB). In this context, the application
of an effective processing workflow able to produce a topography-free
gravity disturbance and quantify its uncertainty is a crucial first step
to delineate gravitational effects correlated to geologic sources of
geothermal interest. This study focuses on an innovative processing
workflow applied to publicly available gravity data in order to produce
stochastic realizations of residuals of the topography-free gravity disturbance. The resulting realizations are compared to a standard
interpolation technique, demonstrating the potential of the stochastic approach
for georesources exploration in sedimentary basins.
