Carbon isotope stratigraphy of dolomites in the early Proterozoic succession, north China

  • ZHONG HUA (a1) and MA YONGSHENG (a2)

Abstract

Four hundred and eighty-four whole rock dolomite samples from early Proterozoic strata have been analysed for carbon isotopes. The carbon isotope composition is strata-specific, but abrupt variations have been observed between the Jianancun and the Daguandong as well as the Daguandong and Huaiyincun formations. The carbon isotope composition of dolomites is believed to reflect δ13C of oceanic total dissolved inorganic carbon during the early Proterozoic and reflect changing rates of organic carbon burial.
