Description
Summary:The 624.15 m glaciomarine sedimentary succession recovered in the CRP-2/2A drillcore comprises lower Oligocene (1000 m/m.y.). Between 306.65 mbsf and the bottom of the drillcore (624.15 mbsf), fewer datums are available to constrain the age model and unique correlation with the MPTS is not possible, although high average sediment accumulation rates are likely. A significant unconformity is identified at 306.65 mbsf, which may represent as much as 5 m.y. of missing time. Additional unconformities at 25.92 and 130.27 mbsf account for c. 16 and 2.5 m.y. of missing time, respectively. The Oligocene-lower Miocene interval documented in the CRP-2/2A drillcore spans about 13 million years, however, it is possible that more time is missing in sequence-bounding unconformities than is represented in the stratigraphic record recovered in the CRP-2/2A drillcore. ... : Supplement to: Wilson, Gary S; Bohaty, Steven M; Fielding, Christopher R; Florindo, Fabio; Hannah, Mike J; Harwood, David M; McIntosh, W C; Naish, Tim R; Roberts, Andrew P; Sagnotti, Leonardo; Scherer, Reed P; Strong, C Percy; Versub, K L; Villa, Giuliana; Watkins, David K; Webb, Peter-Noel; Woolfe, Ken (2000): Chronostratigraphy of CRP-2/2A, Victoria Land Basin, Antarctica.
