oa Exploration of the Gerolekas bauxite mining site using passive geophysical methods

The Gerolekas area, a completely unexplored part of the bauxite mining site of Delphi-Distomon in Central Greece, was investigated with a passive geophysical survey. The passive seismic survey, consisting of the application of Local Earthquake Tomography (LET) and Seismic Interferometry (SI) using the body waves of local microearthquakes and the litho-constrained (using the borehole data and the field geological survey) gravity survey launched at the Gerolekas mining site, along with in situ measurements to have the geophysical parameters of the existing formations, resulted to an integrated geophysical model where deep boreholes confirm the results. Locations of bauxite exploitation provide some reference to correlate with values of geophysical parameters and indicate places in the geophysical model of possible new bauxite sites at reasonable depths.
