In order to improve our understanding of the relationships between the late Hauterivian oceanic anoxic Faraoni event, contemporaneous platform drowning along the northern Tethyan margin and global environmental change in general, we established high-resolution δ13C and δ18O curves for the late Hauterivian and the entire Barremian stage. These data were obtained from whole-rock carbonate samples...

Phosphorus, a Servant Faithful to Gaia ? Biosphere Remediation Rather Than Regulation

The global cycles of the biophile elements phosphorous and carbon are closely linked through their profound implication in two major biogeochemical processes, photosynthesis and biochemical weathering. In photosynthetic processes phosphorous may limit the transformation of atmospheric CO2 into organic carbon, and in biochemical weathering processes atmospheric CO2 may limit the mobilization of...

Decoupling of P- and Corg-burial following Early Cretaceous (Valanginian–Hauterivian) platform drowning along the NW Tethyan margin

During the Hauterivian three important phases of platform drowning, phosphogenesis and mesotrophic carbonate deposition along the northern margin of the Tethys are not mirrored by positive δ[13]Ccarb excursions such as during the Valanginian and Aptian, but rather by decreasing to stable trends. The aim of this study is to understand the decoupling of organic carbon and phosphorus burial during...
