Based on major and trace elements and isotope geochemical data, it is inferred that Sandouding suite is formed by magma melting of Late Archeozoic continent tholeiite source, and its geochemical variation is controlled by hornblende fractional crystallization. Besides fractional crystallization, the geochemical variation of Huanglingmiao suite is related to the mixing between dacitic magma and felsic magma. Dalaoling suite is probably derived from early Precambrian volcanics.

The research shows that in the Yinggehai basin, the formation of CO_(2) reservoir which is crust-sourced and crust-mental-mixed-sourced, mainly controlled by local action of hot fluid in the mud diapir area which is multi terms and multi zones and by physical-chemical mechanism of very thick marine calcareous sandstone and mudstone of Pliocene-Miocene. The volcano- and mantle-sourced CO_(2) in the Qiongdongnan basin and Pearl River Mouth basin is mainly controlled by volcanos activities and by the exist of large faults which reached to base to connect the gas from the mantle. According to different mechanism ang formation of reservoir os the the crustal rock-chemical genesis and volcano-and mantle-sourced CO_(2), we can follow the source of it, analysis and predict the migration and accumulation and distribution model of gas and espacially CO_(2), so as to help to make the plan of petroleum exploration and reduce the risk of exploration.

认为：莺歌海盆地壳源型及壳幔混合型CO2的形成及富集成藏，主要受控于泥底辟热流体晚期分层、分块和多期的局部上侵活动，和巨厚的上新统—中新统海相含钙砂泥岩的物理化学综合作用，且CO2运聚分布规律亦具多期和分层、分区的特点；琼东南盆地东部及珠江口盆地火山幔源成因型CO2则主要受控于幔源型火山活动和沟通深部气源的基底深大断裂的导气配置作用，CO2运聚富集规律与幔源型火山活动及深大断裂的发育展布密切相关，CO2主要来自地壳深部幔源火山活动所伴生的大量CO2；因此，根据壳源岩石化学成因型CO2与火山幔源成因型CO2不同成因机理及成藏条件，可以追踪CO2气源，可分析和预测天然气尤其是CO2的运聚分布规律，可为天然气勘探部署及决策提供依据，可减少和降低勘探风险。

Values, the chemical composition of biotite of them and their petrochemical composition on the corresponding dia grams are all distributed transitionally between the "typi cal areas"; 2 that the micro-elements indicating genesis and the REE distribution parttens display the transitional change from the mines in North to those in South in this region; 3 that their K-Ar age of biotite is distinctively inconsistent with their Rb-Sr age of total rocks; and 4 that there occur several rock body groups with various genetic features which are formed at the corresponding time in the same Pb-Zn ore fields.

具体表现在全岩锶同位素初始比值、黑云母化学成分，岩石化学成分在相应图解上不集中而呈&过渡态&分布；微量元素成因特征及稀土分配型式在本区空间上呈&过渡态&展布；岩浆分异演化过程中各种地球化学演化参数不连续变化；全岩Rb-Sr同位素年龄与黑云母K-Ar年龄值严重不合；同一矿区，普遍发育不同岩性组合的岩体群等等。因此，地洼型多因复成成岩成矿作用在湘南铅锌矿床形成过程中是一个带有普遍性的区域成矿规律。
