Molybdenum isotope compositions and concentrations from the Eagle Ford Group, South Texas

This dataset consists of molybdenum isotope compositions and concentrations of marlstones and limestones of the Eagle Ford Group, South Texas. The data are Late Cretaceous in age, and span several millions of years before and after Oceanic Anoxic Event 2 (~94 Ma). The data were measured on samples taken from two research cores, Iona-1 and Innes-1

Geochemical data from the Cenomanian-Turonian interval of ODP Hole183-1138A

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
