Bulk geochemical and Rock-Eval data of sediment core IKU-7430/10-U-01 (Table 1), supplement to: Langrock, Uwe; Stein, Ruediger; Lipinski, Marcus; Brumsack, Hans-Jürgen (2003): Paleoenvironment and sea-level change in the early Cretaceous Barents Sea – implications from near-shore marine sapropels. Geo-Marine Letters, 23(1), 34-42

The late Volgian (early "Boreal" Berriasian) sapropels of the Hekkingen Formation of the central Barents Sea show total organic carbon (TOC) contents from 3 to 36 wt%. The relationship between TOC content and sedimentation rate (SR), and the high Mo/Al ratios indicate deposition under oxygen-free bottom-water conditions, and suggest that preservation under anoxic conditions has largely contributed to the high accumulation of organic carbon. Hydrogen index values obtained from Rock-Eval pyrolysis are exceptionally high, and...
