Abstract:
In this paper, geochemical facies correlations from Ocean Drilling Program Sites 1168, 1170, 1171 and 1172 are presented. These correlations, integrated with shipboard-determined lithologic and biostratigraphic information, define stratigraphic sequences. The sequence stacking patterns can best be explained by sea-level cycles, indicating that early to middle Eocene glacioeustasy may have affected the Australo-Antarctic Seaway. This conclusion supports some conceptual models, but opposes the model in which Antarctic continental-scale glaciation, and hence glacioeustasy, did not develop until Eocene/Oligocene boundary initiation of the Antarctic Circumpolar Current. The chemostratigraphic correlations also provide stratigraphic refinement of critical chronostratigraphic boundaries including the Eocene/Oligocene boundary. (modif. j. abstr.)
