A brief history of origins and contents of Organically Bound Tritium (OBT) and 14C in the sediments of the Rhône watershed

Autor: David Mourier, C. Cossonnet, Lionel Saey, Hugo Lepage, Frédérique Eyrolle, Loïc Ducros, David Claval, Franck Giner, Yoann Copard

Tritium (3H) and Carbon-14 (14C) are radionuclides of natural (cosmogenic) origin that have also been introduced into the environment by humans since the middle of the last century. They are therefore not compounds that have only recently been releas

The biogeochemical fate of organic matter (OM) entering soils is an important issue that must be examined to better understand its roles in nitrogen cycling and as a natural modulator of soil-atmospheric carbon fluxes. Despite these critical roles, t

Annual fossil organic carbon delivery due to mechanical and chemical weathering of marly badlands areas

Autor: Graz, Y., Di Giovanni, Christian, Copard, Yoann, Mathys, N., Cras, A., Marc, V.

Publikováno v: Earth Surface Processes and Landforms
Earth Surface Processes and Landforms, Wiley, 2012, 37, pp.1263-1271. ⟨10.1002/esp.3232⟩

International audience; A key issue in the study of the carbon cycle is constraining the stocks and fluxes in and between C-reservoirs. Among these, the role and importance of fossil organic carbon (FOC) release by weathering of outcropping sedimenta

Earth Surface Processes and Landforms, Wiley, 2006, 31, N°2 (2), pp.135-153. ⟨10.1002/esp.1319⟩
Earth Surface Processes and Landforms, Wiley, 2006, 31, N°2, pp.135-153. ⟨10.1002/esp.1319⟩

This work relates to the debate on the fossil organic carbon (FOC) input in modern environments and its possible implication for the carbon cycle, and suggests the use of Rock-Eval 6 pyrolysis as a relevant tool for tracking FOC in such environments.
