Summary

Abstract:
Sand petrographic data were collected on the 500-2000 micron fraction of LGM-age till from the Ross Embayment. Moraine samples from the Beardmore, Byrd, Darwin/Hatherton Glaciers, Mt. Achernar and Allan Hills were obtained from Dr. Gunter Faure (Ohio State) and Dr. James Bockheim (U. of Wisconsin, Madison). Samples of till from beneath the Siple Coast Ice Streams were obtained from Dr. Hermann Engelhardt (Cal Tech). Ross Sea till samples were obtained from the Antarctic Marine Geology Research Facility (FSU). A few grams of unsieved splits of most of the samples, as well as the grain mounts of the sand fraction are housed at the Sediment Analysis Lab at IUPUI. The data generated from this project include percentage data of mineral and lithic fragments, particle size distributions and elemental abundance. Isotopic analyses of the samples were completed by Dr. Lang Farmer (Univ. of Colorado, Boulder). |
