The Mesozoic Era experienced several instances of abrupt environmental change that are associated with instabilities in the climate, reorganizations of the global carbon cycle, and elevated extinction rates. Often during these perturbations, oxygen-d...

Hydrogen isotopes in Quaternary mammal collagen from Europe (2016)
Journal Article
Gröcke, D., Sauer, P., Bridault, A., Drucker, D., Germonpré, M., & Bocherens, H. (2017). Hydrogen isotopes in Quaternary mammal collagen from Europe. Journal of Archaeological Science: Reports, 11, 12-16. https://doi.org/10.1016/j.jasrep.2016.11.020

Of the most abundant elemental constituents of organic matter, hydrogen has received the least attention due to its exchangeability with ambient water. The development of steam equilibration using two isotopically distinct waters can enable the user... Read More about Hydrogen isotopes in Quaternary mammal collagen from Europe.

Stratabound massive sulfide deposits are widespread along the Middle-Lower Yangtze Metallogenic Belt (MLYMB) and serve as an important copper producer in China. Two contrasting genetic models have been proposed, interpreting the stratabound massive s...

Owing to Rhenium (Re) having no known biological role, it is not fully understood how Re is concentrated in oil kerogens. A commonly held assumption is that Re is incorporated into decomposing biomass under reducing conditions. However, living macroa...
