(Table T1) Bulk calcium carbonate content of ODP Hole 194-1198A sediments

Weight percent calcium carbonate (wt% CaCO3) content was determined on 328 samples from Ocean Drilling Program Hole 1198A. Two intervals were analyzed, one within lithologic Subunit IA between 14.52 and 41.13 meters below seafloor (mbsf) (25 cm sampling interval) and one within Subunit IB between 67.42 and 100.12 mbsf (15-30 cm interval), allowing the comparison of the nature of cyclic siliciclastic-carbonate variations during the late and early Pleistocene. Overlap with a previously analyzed interval in Hole 1198A illustrates the good agreement in data generated by differing methodologies and extends the continuous record of bulk wt% CaCO3 from 0 to 41.13 mbsf. Although Subunits 1A and 1B exhibit nearly the same variability, from 93% to 63% and 94% to 68%, respectively, Subunit 1A is characterized by a longer cycle length.

Age determination of sediment core M1_251, Persian Gulf (Table 1)

Sediments from a 3.40 m core out of the Persian Gulf were investigated for their content of straight chain paraffins and fatty acids. The samples range in age between 2000 and 9000 years (C-14-age of organic C). They contain 100-300 ppm of extractable fatcompounds and 20-70 ppm of hydrocarbons. There is no connection between the original distribution of the homologous series of n-fatty acids and n-paraffins. However, there is evidence that part of the n-fatty acids was reduced to n-paraffins, although the sediment itself does not look as if it were deposited under reducing conditions.
