Special issue}, month = {Sep}, note = {P(論文), 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 14 (Wright Valley) and DVDP 12 Taylor Valley) shows that diatoms are not helpful in interpreting those sedimentary sections. Analysis of a newly discovered mirabilite deposit on the Ross Ice Shelf indicates that mirabilite can be formed by the injection of saline brines to the surface of ice shelves and that other mirabilite deposits in the McMurdo region may reflect ancient ice shelf thicknesses rather than former sea levels. Finally, there is some evidence that diatoms grew in freshwater pools during a hyaloclastite phase of Ross Island volcanism.}, pages = {165--175}, title = {A Diatom Report on DVDP Cores 3,4A, 12, 14, 15 and Other Related Surface Sections}, volume = {13}, year = {1979} }
