ArLiTA aims at characterizing the structures and the deformation patterns of the Terre Adélie and George V Land (East Antarctica: 135 to 145° E). The ArLiTA project includes multidisciplinary approaches and combines various analyses and interpretation methods, in order to relate field observations to geodynamic models. Those includes studies from the crystal scale to regional structures mapped by seismological data analysis and includes measurement of the anisotropy of magnetic susceptibility (AMS) to map the deformation patterns (foliation, lineation) of the different crustal blocks from the Neoarchean and Paleoproterozoic crustal segments. ArLiTA project also includes petrological and geochemical analyses to investigate relationships between the deformation structures and the transfers of geological fluids (silicate melts, hydrous or carbon-rich fluids, etc…) within the crust. ArLiTA deployed four broad band three components seismic stations east of the GEOSCOPE station DRV located at the Dumont d’Urville French base. These stations were operating from Nov 2009 to Dec 2012 along the Terre Adélie and the George V Land coastal area and improves the instrumental coverage of East-Antarctica and of the Terre Adélie Craton (TAC). https://dossier.univ-st-etienne.fr/arlita/www/
