It is shown that in the basins in the Eastern China, onshore and offshore, the formation of CO2 reservoir is crust-sourced and crust-mantal-mixed-sourced, mainly controlled by local activity of hot fluid into the mud diapir area in multi-phase and multi-zones in physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO2 in the Qiongdongnan Basin and Pearl River Mouth Basin is mainly controlled by magmatism and major faults which cut through the basements and link to the mantle gas.
