Preliminary Results of Bitumen and Whole-Rock Elemental Analyses of CRP-2/2A, Victoria Land Basin, Antarctica
Sediments and rocks recovered in CRP-2/2A coring operations contain relatively little organic matter (average TOC=0.28%) and very small amounts of solvent-soluble organic matter. Because Early Oligocene sediment included significant amounts of coal detritus, TOC values are higher in Early Oligocene...
