Abstract:

Geochemical data from Ocean Drilling Program Site 1138A, core 69, spanning the Cenomanian–Turonian boundary interval (~94 Ma). The data were generated from marine sediment in the archive half of the core, which was opened and sampled for this project following approval from the IODP curatorial advisory board. The data consist of: (i) Bulk organic geochemistry (total organic carbon, hydrogen and oxygen indexes, total inorganic carbon) measured by Rock Eval pyrolysis and coulormat titration; (ii) Bulk organic carbon isotopes, measured on decarbonated sediments; (iii) Bulk sediment elemental concentrations measured by ICP-MS; (iv) Bulk sediment molybdenum isotopes, measured by MC-ICP-MS; (v) n-alkane compound-specific carbon isotopes measured by GCMS-IRMS; (vi) Maceral assemblage compositions, measured by visual petrography.
