GPR > GPR in a Quarry

We present the application of the GPR method in a quarry. The quarry is dug in 100-m thick limestone, composed of horizontal beds of thickness between 1 and 2.5 m, intersected by sub-vertical fissures. Limestone resistivity (Comblanchian white oolite) ranges between 40 and 200 ohm/m. Two boreholes have been drilled: a vertical borehole and a highly-deviated borehole.
