The Rochelec dataset gathers petrophysical and geoelectrical data from the Rochechouart impact structure (France). Since 2017, about 10 geophysical field campaigns were performed on this eroded structure. Among other techniques, geophysical downhole logging, electrical resistivity tomography and controlled-source audiomagnetotelluric data were acquired. In parallel, we measured the electrical resistivity and porosity of some core samples coming from drillings performed in fall 2017 at several sites of the impact structure. These multiscale electric data allows to...
