Sebastian Clauser, Maurice Renard & Gilbert Richebois
Trace element contents (Sr, Mg, Mn, and Fe) and the composition of oxygen and carbon isotopes show that late burial diagenesis did not play an important role in pelagic carbonate chemistry in the bulk carbonates recovered from Holes 638B, 638C, and 641C (except for anoxic pore-water diagenesis in Valanginian sediments). The evolution of these different geochemical markers documents the importance and global extent of the Barremian ocean chemistry crisis. A reconstruction of paleoceanographic and climatic...
