Laboratory assessment of the impact of chemical oxidation, mineral dissolution, and heating on the nitrogen isotopic composition of fossil‐bound organic matter
Fossil‐bound organic material holds great potential for the reconstruction of past changes in
nitrogen (N) cycling. Here, with a series of laboratory experiments, we assess the potential …
