Connecting Geophysics with Geology (CGG)

The scattered geological exposures of Antarctica have been mapped and understood to strongly varying degrees. The close vicinities of stations are often better studied than remote areas where logistics is demanding. There are still unmapped areas. The systematic aerogeophysical surveying starts to reveal the sub-ice geology of the continent. Major lineaments and the spatial extent of individual tectonics blocks become apparent, the interpretation of which is however often difficult so far. The connection of the exposed geology and the geophysics is often loose, specifically in mountain/nunatak areas that have only sketchily been studied. Key areas need to be identified where detailed geological field studies and focussed geophysics should be carried out in order to understand the significance of major geophysical lineaments and the boundaries of tectonics blocks. 

The SCAR Connecting Geophysics with Geology (CGG) Group aims to identify highest-priority areas where lineaments and/or apparent tectonic block boundaries intersect with outcrops, provide improved geological maps, improve connections to adjacent continents within Gondwana/Rodinia and project the knowledge of these into Antarctica, and identify worthy drill sites for basement recovery and connect to other Antarctic drilling communities.
