英文摘要	The timing of mantle-derived CO2charging in sedimentary basins is the basis for studying CO2-sandstone interactions and CO2-oil interactions. In general, the time of the volcanic eruption near the CO2gas reservoir is considered to be the time of mantle-derived CO2charging. However, this approach is not suitable for hydrocarbon-bearing basins that have experienced multiple volcanic events. In this paper, using dawsonite-bearing sandstones contained in an oil-bearing CO2gas and oil reservoir in the southern Songliao Basin as the object of the study on the basis of paragenetic sequence and fluid inclusions, we establish a mineral dating method for determining the time of mantle-derived CO2charging. In this method, the mineral used for dating is dawsonite, which is formed under a high CO2partial pressure and records the migration and aggregation of mantle-derived CO2in geologic history. By interpreting the dawsonite-bearing sandstone in the southern Songliao Basin, we find two hydrocarbon charges and one CO2charge and that the mantle-derived CO2charging occurred slightly later than or quasi-simultaneously with the second hydrocarbon filling. Combining the currently known time of hydrocarbon reservoir formation and the time of tectonic fracture development, we deduce that the mantle-derived CO2formed the dawsonite in the southern Songliao Basin at the end of the Cretaceous (end of the Mingshui period) and the beginning of the Paleogene. © 2016 Elsevier Ltd.
