The Biomarkers in the Mesoproterozoic Organic‐rich Rocks of North China Craton: Implication for the Precursor and Preservation of Organism in the Prokaryotic Realm

Abstract: have suggested that the atmospheric oxygen concentration during the Mesoproterozoic was higher than previously believed (Planavsky et al., 2014), may have reached 4-8% PAL (present atmospheric levels). The trace element concentrations, organic carbon content, and biomarker data of the 1400 Ma Xiamaling (XML) Formation in the North China Craton (Zhang et al., 2016(Zhang et al., , 2017 implied that that surface ocean was aerobic during the Mesoproterozoic. This promoted the flourish of phototrophic plankton duri… Show more

“…Biomarker compound parameters are another tool for evaluating the maturity of organic matter in sedimental rocks [51,54,55]. During the heating of hopanes and steranes under geological conditions, the R conformation is converted to the S conformation, forming a mixed conformation of R + S. In general, a higher 22S/(S + R) ratio represents higher maturity [52].…”
