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。

The research shows that these basins alternate between uplift and concave and that their spreading directions follow certain rule. The 6 NEE-trending basins are of early Jurassic epoch, some of which may contain coal-bearing strata and minable coal seams of Beipiao Formation. The 12 NNE-trending basins are all of early Cretaceous epoch, among which Badaohao, Leijia and Xielintai Basins have relatively good coal-bearing property and can serve as coal-searching prospect area.

The differences in reservoiring conditions of natural gas and oil, as well as the multicycle developments and evolution histories of major gas bearing basins in China, and the geological environments characterized by relatively active tectonic movements in later period have resulted in the forming conditions of gas fields in China to be more complicated than those in many basins all over the world.

由于天然气与石油在成藏条件上的差异和中国主要含气盆地多旋回的发展演化历史、晚近时期构造运动比较活跃的地质环境，中国气田形成条件较世界上许多盆地复杂和成藏类型较多。总结中国大中型气田的成藏历程，可以新近纪、古近纪和中生代为界将气田的形成归为 4类：1超晚期生烃成藏型；2晚期生烃成藏型；3早期生烃聚集和晚期定型成藏型；4早期生烃成藏型。在这 4类中，以晚期和超晚期成藏和定型为主且分布最广、天然气前景最好、是中国天然气最主要富集领域。早期生烃成藏型在保存良好的盆地也有较好的前景。

Recently, the discovery of different kinds of commercial hydrocarbon flow in Neopaleozoic of Ordos Basin, Jizhong and Huanghua depression in Bohai Bay Basin, and Qinshui Basin has indicated that Neopaleozoic is a subject reservoir with broad prospect in North China.

Meanwhile, based on the features of nonmarine basin, sequence stratigraphic models of depression and faulted depression are built, so they supply useful theoretical guidance for exploration of oil and gas.

本文引入新的概念和方法，同时根据陆相盆地特特建立了陆相坳陷盆地地层序模式及陆相断陷盆地中陡坡型和缓坡型两类地层层序模式，为油气勘探提供有用的理论指导。

It stably subsided after its formation. During Palaeogene ang Neogene salt-forming, Kuqa basin experienced strong-weak-strong tectonic stages, and its center of subsidence moved gradually from north to south and depocenter from northwest to east and southeast. Because of tectonic differentiation, series of second depression formed in Kuqa basin.

盆地自形成以来一直处于稳定的沉降状态，在古近纪和新近纪成盐期，盆地经历了强-弱-强3个构造演化阶段，其沉降中心由北而南逐渐迁移，沉积中心由北西逐渐向东、南东方向迁移，盆地内的构造分异渐趋明显，形成了一系列次级凹陷。

During the Early Carboniferous, glacio-eustasy and the palaeogeographic environment of Qiangui intra-platform basin played crucial roles in controlling the geobiological processes, the formation and distribution of basinal facies hydrocarbon source rocks.

Silicalites, predominated by pelitic silicalite, occur in collisional zones and back-arc basins. In the collisional zones, they occur as rock sheet as an important part ofophiolitic mé lange, belonging to ophiolitic mélange type silicalite. In the back-arc or interarc basin, they occur as pelitic silicalite intercalation varying in thickness, characteristic of "silica merl",and belonging to abyssal back-arc basin type or carbonate type silicalite. In the magmatic arc, they occur as intercalation related to volcanic hydrotherm or volcalic exhalation, belonging to volcanic arc type silicalite.
