Comment:
This dataset merges information from five sources and adds newly calculated data. Original radionuclide data and sand content are taken from Frank and Eisenhauer 1996. The age scale and stable isotopes were taken from Spielhagen et al. 2004, with AGE [ka BP] being based on calibrated 14C ages and "Age dated [ka]" being a radiocarbon age with 402 years reservoir correction. From these data, 230Thex recalculated (230Th-234U), authigenic uranium (assuming 238U/232Th of 0.6), ingrowth of 230Th from authgenic uranium (using the Spielhagen et al. 2004 ages) and 230Thex noauth (corrected for ingrowth from authigenic uranium but not decay) were calculated.
