A Diatom Report on DVDP Cores 3,4A, 12, 14, 15 and Other Related Surface Sections
This paper covers diverse topics. A glacial till in the western Ferrar Glacier area shows that glacial drainage patterns in southern Victoria Land changed during the Victoria Orogeny. A recently discovered section provides further evidence of a Miocene fjord in Wright Valley. Diatom analysis of DVDP...
