GeoKarla : Geophysical and petrophysical data of the Karla impact structure

The GeoKarla dataset gathers geophysical and petrophysical data acquired over the Karla impact structure (Tatarstan, Russia). In September 2019, a field campaign on this eroded and buried structure was performed. Magnetic and gravity field observations were done, as well as geological mapping and sampling. Further petrophysical analyses in laboratory were performed on rock samples. All these data reveal - for the first time - a clear but unusual geophysical signature of the Karla impact structure. ==== acknowledgements ====== The associated research project was funded by: Russian Foundation for Basic Research RFBR grant no.18-55-5014 CNRS PRC French program Institutes/Participants: * Aix-Marseille Université, CNRS, IRD, INRAE, Aix-en-Provence, France Quesnel, Y., Rochette, P., Gattacceca, J., Uehara, M. * Institute of Geology and Petroleum Technologies, Kazan Federal University, 4/5 Kremlyovskaya Str., 420008, Kazan, Russia Bezaeva, N.S., Kuzina, D.M., Nasyrtdinov, B.M. * V.I.
