Abstract: It has been proven that thermochemical sulfate reduction (TSR) took place extensively in the Lower Triassic carbonate reservoirs in Northeast (NE) Sichuan (四川) basin. We have carried out analyses on bulk rock compositions and isotope ratios together with petrography and fluid inclusions to assess the impact of TSR on diagenetic process of Triassic dolomites. In this article, TSR-related burial diagenesis is characterized by precipitation of calcite cement with negative δ13C values and high homogenization temperature...
