The results indicated that the formation of fault basin constrained by magnetic crystalline basement. The more complex of the crustal tectonic, the greater the difference mechanical strength between crust media, the smaller thermal water release less, the easier bred major earthquake.6. Mapped the new quaternary tectonic map of four fault basin based on the data of shallow seismic profiles, drilling, and the redrawn fault system divided by the potential data processing, etc.
研究结果表明断陷盆地的形成受磁性结晶基底的制约;地壳结构越复杂,地壳介质之间的力学强度差异越大,热水点年释放量越小,就越容易孕育和发生大的地震。6、利用浅层地震剖面、钻井等资料,并参考重磁划分的断裂系,新编制了山西四个断陷盆地的第四系构造图。

In some way, the nature of the geochemical field shows that the deep fluid took part in the energy mineral reservoir formation and mineralization.2、 In zones with the strong tectonic activity and basement faults, the elements combination of petroleum is complex and the material from deep resource can be found in which. The character of elements geochemical and carbon isotope all show that there are deep fluid components in some Energy Minerals. The material source of the water accompanying with petroleum reservoir is complex, and which with multi-sources. The character of elements geochemical shows that the uranium of Dongsheng uran ore comes from the upper crust, the greyish-green gritstone and hoary kaolinised argillaceous siltstone is important for the formation of uranium deposits,and the grey gritstone is great potential to surveying uranium deposits .

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton
位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明,辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列,原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融,在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融,而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征,该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景,并可能经历了碰撞过程。

In accordance of dynamical analysis to asymmetric basin forming, it is restricted doubly by crust multi-layer rheological structure and regional geotectology background in the Lower Yangtze regional crust, especially in close relationship with action of C-layer (18-20km) in the Lower Yangtze region crust. After quantitative analysis of mutual relation between the basin geometrical feature and the crustal structure, a new way will be supplied to the research of Mesozoic-Cenozoic sedimentary basin evolution and the oil -gas exploration in the Lower Yangtze region.
在此基础上,对非对称盆地形成的动力学分析认为,它受下扬子地区地壳多层次流变结构及区域大地构造背景的双重制约,尤其与下扬子地区地壳C层(18-20Km)的活动密切有关,定量分析了盆地的几何学特征与地壳结构之间的相互关系,为下扬子地区中新生代沉积盆地演化的研究及其油气勘探提供了新的研究途径。

Near post 47km there is a high dip angle fault stretching from the lower part of the upper crust to the top of the crust_mantle transitional zone. This strike_slip fault has a direct bearing on the occurrence of the Jiashi strong earthquake swarm and is an inferred causative fault for the swarm (1997) according to this study.
