Collaboration with the French colleagues from Geosciences Montpellier

For over 15 years the Institute of the Earth’s Crust in Irkutsk is successfully developing collaborative researches with the French colleagues from Geosciences Montpellier (Dr. J.F. Ritzand others), Geosciences Azur (Dr. C. Larroque and others), Geosciences Rennes (Dr. M. Jolivet), ISTerre Savoie (Dr. R. Vassallo and others) as part of the study of active tectonic deformations and relief formation processes in the Baikal-Mongolian region. The research resulted in publications in international scientific journals.


The active faults of the Baikal-Mongolian region were studied repeatedly during the Russian-French and Russian-French-Mongolian fieldwork including morphotectonic and paleoseismological research in the largest fault zones therein – Tunka, Main Sayan, Bolnai, and Bogdinsky. The fieldwork yielded the data on fault kinematics, displacement rates along the faults, and large-earthquake recurrence intervals (Larroque et al., 2001; Arjannikova et al., 2004; Vassallo et al., 2007; Rizza et al., 2015; Arzhannikova et al., 2015). Collaborative research for studies of the Meso-Cenozoic relief evolution produced significant results, particularly referring to identification of the vast early-Jurassic peneplanation surface in Central-Asia (Jolivet et al., 2007). Not least important are the results concerning time determination for reactivation of tectonic processes related to region-affecting lateral compression produced by the Indo-Asian collision (Vassallo et al., 2007; Arzhannikova et al., 2011), tracing the history of late-Pleistocene glaciation in the Sayan-Tuva Upland using cosmogenic isotope dating of glacial relief forms (Arzhannikov et al., 2012; Arzhannikov et al., 2015), tracing the Meso-Cenozoic evolution of relief in the Oka-Jombolok area of East Sayan from the fission-track and cosmogenic-isotope data (Jolivet et al., 2013(1)), and model development for the history of the Baikal rift and adjacent areas with compressive and tensile deformation regimes in a uniform stress filed (Jolivet et al., 2013(2)).
