The study shows that in various continental downfaulted basins in eastern China,the China East Sea basin of the southeast sea region and the continental shelf—Qiongdongnan basin and Zhujiangkou basin—of the northern South China Sea,CO2 in CO2 reservoirs and CO2-rich oil/gas reservoirs is of typical volcanic mantle-derived type and that its migration and concentration is mainly controlled by mantle-derived volcanism and gas-conducting distribution of deep basement faults connected with the gas source at depth. CO2 is mainly sourced from substantial amount of CO2 associated with mantle-derived volcanism at the deep level of the crust. CO2 in the CO2 reservoirs and CO2-rich oil/gas reservoirs in the Yinggehai basin on the continental shelf of the northern South China Sea is of crust origin and crust-mantle mixing origin and mainly controlled by local,layer-by-layer and zone-by-zone,multiple intrusion of late hydrothermal fluids in mud diapir areas and physico-chemical processes of very thick Pliocene-Miocene marine calcareous sandstone and mudstone.

研究表明，中国东部陆上诸断陷盆地与东南沿海海域的东海盆地及南海北部大陆架琼东南盆地和珠江口盆地CO2气藏及高含CO2油气藏中，CO2均属典型的火山幔源型成因，其运聚富集主要受控于幔源型火山活动与沟通深部气源的基底深大断裂的导气配置作用，CO2气源主要来自地壳深部幔源火山活动伴生的大量CO2；南海北部大陆架西区莺歌海盆地CO2气藏及含CO2油气藏中的CO2，属于壳源型及壳幔混合型成因，主要受控于泥底辟热流体晚期分层分块多期的局部上侵活动与沉积巨厚海相含钙砂泥岩的物理化学作用，其运聚分布具多期和分层分区的特点。
