This study encompasses an investigation of the heavy mineral composition of early Oligocene-Quaternary glacial and glaciomarine sediment sequences from the Victoria Land Basin and the fjords of the South Victoria Land, Ross Sea, Antarctica. The sediment cores used were recovered during different international drilling campaigns (DVDP- 12, CIROS-2, MSSTS-l, CRP-l, CRP-212A). The main objectives were to identify possible source rocks and to unravel the provenance regions of different heavy minerals and mineral groups. Moreover, with the available data an attempt to reconstruct the general development and codiguration of the Antarctic ice sheets during the Cenozoic was alsomade ...
