Morphostructure of the Djavakhet volcanic upland (Southern Georgia)

Abstract

Field observations and remote sensing data proved morphostructures of central type to be widespread in the area of .active Late Cenozoic volcanism in southern Georgia. The Djavakhet morphostructure of radius about 30 km is identified and close connections are shown (both spatial and genetic) to exist between its tectonic frame, geologic substance and surface topography. The morphostructure has deep roots within the earthcrust at the «granitic» and «basaltic» layers interface. The present-day topography results from volcanic material accumulation, block tectonics and also active glacial erosion and fluvial activity.
