DOI: 10.1016/j.gca.2020.09.024
Abstract: Abstract Magnesium (Mg) isotopes fractionate during rock/mineral weathering and leaching, secondary mineral neoformation, adsorption/desorption, and plant-related Mg recycling, but the mechanisms and extent of fractionation are not well understood. Here, we report the fate of… read more here.

Stable Isotope Geochemistry of the Organic Elements within Shales and Crude Oils: A Comprehensive Review
Sign Up to like & getrecommendations! Published in 2021 at "Molecules"
DOI: 10.3390/molecules27010034
Abstract: Over time, stable isotopes have proven to be a useful tool in petroleum geochemistry. However, there is currently insufficient literature on stable isotope geochemistry of the organic elements within shales and crude oils in many… read more here.
