摘要
The petrological records of mantle-magmatic CO2 leakage, which occurred in Honggang anticline, southern Songliao basin, can be revealed by studing on spatial distribution and the occurrence of dawsonite cements and also the characteristics of fluid inclusions in dawsonite-bearing sandstones. In Honggang anticline, dawsonite is widespread in Qingshankou Formation, in Quangtou Formation and Yaojia Formation come second. Most of the dawsonite-bearing sandstones do not contain CO2, while some of the dawsonite-bearing layers contain oil. As a consequence, the channel for CO2 leakage is Honggang fault, while the leakage time should be early than the second section of Mingshui Formation.
