Recently, based on the field work we have recognized that those basic rocks actually were oceanic basalts intergrown with Late Paleozoic deep water deposits, rather than continental rift basalts.

根据近年的野外工作，我们已经指出这些基性岩实际上是与晚古生代深水沉积共生的海相玄武岩，而不是象过去认为的大陆裂谷型玄武岩。

Yi-Shu fault is a lithosphere fracture belt with a long history, which formed a rift fracture system by the effect of the Kula plate and the Pacific plate movement during Mesozoic.

The biometallogenesis system of Jinya gold deposits consists of the following procedure: pre-concentration of gold and metallogenic matter in living organisms in Luodian-Danchi rift depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of gold and metallogenic matter in organic fluid from basin to Lingyun underwater carbonate platform and concentration at its boundary convex (palaeo-blind-mountain) during basin compaction ; metallization due to depth thermal fluid making organic fluid thermal degradation and forming new fluid which riches in gold and sulfur, and the fluid migrating upward and depositing in upside ore-controlling structures because of absorptions by organic carbon and atc.

通过研究金牙金矿作用的生物成矿系统内容为：在早、中三叠世罗甸—丹池裂谷盆地接受沉积时，生物对金等成矿物质就存在预富集作用；在成岩过程中，生物转化为有机质及有机热流体，对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用；在盆地压实成岩作用中，盆地中有机热流体向凌云水下碳酸盐台地运移，并在台地边缘外凸部位集中，此过程流体携带大量成矿物质，对金等成矿物质存在迁移集中作用；深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液，含金热液上移在构造通道中沉积并被有机碳再次吸附，最终形成金矿床，对金存在成矿作用。

We analyzed the tectonic differences and deep geodynamic characteristics based on the tomographic results, which show high velocity anomalies at the uppermost mantle beneath the northeast SCS, and depict the lithospheric mantle extension from South China continent to marginal sea. Because of the low temperature and thick lithosphere beneath the northeast SCS, it seems no magma intruded from mantle, so we inferred that the rift may only occur in the crust rather than extend to the upper mantle, which shows the nature of nonvolcanic continental margin.

结果表明：南海东北部表现出陆架地区的岩石层特性，属于华南大陆向海区的延伸，岩石层厚度较大，现今不存在大规模的地幔热流活动，推测大陆边缘张裂作用仅限于地壳内部而没有延伸进入上地幔，具有非火山型大陆边缘的深部特点。
