Abstract
This paper presents a study where resistivity and integral chargeability three-dimensional (3D) models, representing a volume in the vicinity of a rock quarry is compared to a quasi-3D characterization of rock mass volume. By repeating geological mapping, i.e. with unmanned aerial vehicles, ground based high resolution photography and sampling, as the quarry operation reaches further into the rock volume mapped with geophysics, we retrieve a semi-continuous geological characterization of the same rock mass volume characterized by the geophysical investigations. This enables a detailed comparison between geophysical results and rock volume, where factors such as fracture and weathering zones or rock type is being considered.
