Journal ArticleDOI

The phosphorus cycle, phosphogenesis and marine phosphate-rich deposits

TL;DR: In this article, a compilation of marine sedimentary phosphorus burial rates for the last 160 Myr suggests that natural variations have occurred that span one order of magnitude, which suggests that uniform interpretations with respect to the emplacement of major phosphorite deposits should be treated with caution.
Journal ArticleDOI

Phosphogenesis, carbon-isotope stratigraphy, and carbonate-platform evolution along the Lower Cretaceous northern Tethyan margin

TL;DR: In this paper, the authors distinguish three different stages in the evolution of the Tithonian to Aptian (Early Cretaceous) northern Tethyan carbonate platform: (1) carbonate production in the coral-oolite mode, (2) platform retrogradation and destruction, condensation, and phosphogenesis (that is, platform drowning), and (3) platform regeneration following phases of widespread emersion during late sea-level highstands.
Journal ArticleDOI

Phosphorus and the roles of productivity and nutrient recycling during oceanic anoxic event 2

TL;DR: In this paper, four sections documenting the impact of the late Cenomanian oceanic anoxic event (OAE 2) were studied in basins with different paleoenvironmental regimes.
Journal ArticleDOI

Paleoceanographic changes during the early Cretaceous (Valanginian-Hauterivian): evidence from oxygen and carbon stable isotopes

TL;DR: The authors investigated Valanginian-Hauterivian bulk rock and belemnite samples from Vocontian Basin sections in southeastern France for their stable carbon and oxygen isotope signature.
Journal ArticleDOI

Investigating the history of East Asian monsoon and climate during the last glacial-interglacial period (0-140 000 years): Mineralogy and geochemistry of ODP Sites 1143 and 1144, South China Sea

TL;DR: A detailed multiproxy study, including bulk and clay mineralogy, grain-size analysis, phosphorus geochemistry (SEDEX extraction), organic matter characterization, and nitrogen stable isotopes, was carried out on samples from ODP Sites 1143 and 1144 (Leg 184, South China Sea), covering the past 140,000 years.
