    dct:description "Measurements of the nitrogen content of hydrothermal graphite deposits and associated silicate rocks. The samples are of Paleoproterozoic age and allow constraining the behavior of nitrogen in abiotic hydrothermal graphite-forming systems. The results provide context for evaluating the biogenicity of Eoarchean graphite. More details are presented in Stüeken, E.E., Szilas, K. and van Hinsberg, V.J., 2023, Chemical Geology, 617, p.121274." ;
