In the austral summer 2017/18, a three person team performed geological and geological-glacial field mapping in the Convoy Range, at the scale 1/250000. Activity was heli-supported, starting from the Italian Mario Zucchelli Station, with two principal targets: 1) to complete geological mapping for the area between 76° and 76°30 ́ S, filling a gap existing between the GIGAMAP maps (Pertusati et al., 2016) to the north and the geological maps by GNS Science - New Zealand to the south (Gunn & Warren, 1962; Pocknall et al., 1994); 2) to collect new data (stratigraphic, structural, sedimentological, petrographic and geochronological data) to better characterize the lithotectonic units cropping out in the investigated area. In more detail, in Antarctica the activity included: - geological and geological-glacial field mapping. - photogeological analyses, to support the field work; - rock sampling. On return from Antarctica the activity comprised: - digitisation of the new cartographic data and their integration in the Geomap dataset; - elaboration of structural data; - microstructural analyses; - minero-petrographic analyses of rocks and glacial deposits.
