Ch002 24 GEOCHEMICAL TRANSFORMATIONS OF SEDIMENTARY SULFUR obtained in the pyrolysis of synthetic polysulfide cross-linked polymers (19). Upon further maturation of the sedimentary organic sulfur, hydrogen sulfide also is eliminated along with elemental sulfur. Using the relative abundance of 2,3-dimethylthiophene in pyrolysates of kerogens as a measure of the organic sulfur content, Eglinton et al. found that in natural maturity sequences, and in thermal experiments, this parameter decreased, indicating a decrease in organic sulfur with maturation (47,48).
