RochElec : Geoelectrical investigations on the Rochechouart impact structure (France)
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 better characterize the different lithologies outside the drilling sites, and their associated geometry.

- Statement
-
Electrical resistivity measurements were performed with different methods and scales. First, we used downhole logging tools (including EM51 and DLL3) in most of the 2017 drill holes.
Complementary electrical resistivity measurements were done on some of the core samples. Electrical resistivity tomography (ERT) profiles were performed using an ABEM Lund Imaging System at and around each drilling site.
Lastly, controlled-source audiomagnetotelluric (CS-AMT) observations were acquired using Phoenix T-3 with RXU-TMR and V8 receivers at greater scale to investigate the lateral and vertical electrical properties of the Rochechouart impactite and target formations.
