Hutuo group of greenschist facies of the mainly sedimentary rocks appears a tectonic style of the huge invert-fan synclinorium in Wutaishan, illustrates the material components of the above crust and inner continental orogenesis. It is a typical example of the tectonic—magma event in the world at 2100—1800Ma, would be a new research hot after Rodinia.

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境,部分岩石具有碰撞期或非造山期花岗岩的某些特征,表明碰撞后阶段既是碰撞造山过程的延续,又是向非造山环境的构造转换时期,因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明,区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔,由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

Tagore was appalled by it, both because he thought that introducing politics into a situation in which a lot of the people killed were children who had nothing to do with untouchability was a pretty nasty thing to do.

泰戈尔为此震惊,因为他认为,政治介入到无数人死亡,而且死亡的孩子们与贱民无关,这真是一个很丑恶的事。他还认为,地震具有科学的理由,这是人们应该理解的,要理解地球的实质,要理解地壳的运动。

Combine with the "Post-collisional" geochemical characteristics and the participation of mantle-derived composition;the emplacement events of granites maybe represent a transition from collision to orogenic collapse,and the magma maybe derives from the breakoff or delamination processes,then ascend to the upper crust along the strike-slip or transtensional fault.

结合花岗岩&后碰撞&的地球化学特征及岩浆形成过程中幔源物质、热的参与等认为这些花岗岩的形成应代表了造山带由碰撞造山向造山带垮塌过渡的早期阶段,岩浆的形成可能由一些深部过程如拆沉、板片断离等引起,并沿这一时期中浅部地壳的走滑或者走滑伸展构造侵位。

Researches to the gold-bearing quality of sedimentary and magmatic rocks show that most of these rocks have more gold content than the average of the upper crust. Further evidences are quoted to support the view that fluids exist in shallow crust have the ability resolve some gold. Moreover, in the convergent compression, deep melting of the lower lithosphere can bring some Au and mineralization materials and move up to upper crust. Regional faults, which formed in geosynclinal and diwa periods, controlled the partial distribution of intrusions and gold mineralization belts, i.e.

区域地层和岩浆岩的含金性表明,岩浆岩和大部分地层均具较高的金异常含量,而进一步的研究表明浅部地壳的流体对地层中的金具一定的溶解和搬运迁移能力;而在汇聚挤压构造体制下由深熔作用生成的岩浆可以从岩石圈深部携带部分金和其它成矿物质并迁移到地表浅部,地槽期和地洼期形成的区域断裂构造共同控制了中新世岩浆的侵入和金成矿带的分布。

The Paleoproterozoic Beidahe Group-complex remains as continental shivers in the interior of the North Qilian orogen. In its early stage of development, there occurred abundant amphibolite. The protolith of the amphibolite is basalts. The Alk-∑FeO-MgO plot, REE features and Rittmann index show that the protolith belongs to the calc-alkaline suite and exceptionally shows the subalkaline character. The rock is characterized by higher Al2O3 and ∑FeO and lower Mg#, indicating that it has a higher degree of compositional evolution and that the formation of volcanic rocks is related to activation of older crust. Highly fractionated REE patterns and amphibolite on the Ti-Zr-Y plot, Ni-FeO/MgO plot and Ta/Yb-Th/Yb plot all indicate the characteristics of volcanic arcs and active continental margins. On the geochemical diagram of basalt, the overall REE features are in the main analogous to those of calc-alkaline island-arc basalt, with Sr87/Sr86=0.71617–0.72033,Nd143/Nd144=0.512414–0.512495 and εNd=–2.79 to –4.37,εSr=245.78–305.3, showing that the magma was derived from the crust or subjected to contamination with the lower crust below the continent.

On the other hand, the low-Ti/Y type picrites and low-Ti basalts were also probably derived from the same plume source, but magmas of the low-Ti/Y type picrites most likely experienced a mixture with more than 15% bulk SCLM material; and magams of the low-Ti basalts were probably contaminated with over 15% melt from SCLM.

The results of the study indicate:(1) the stress, strain and velocity fields as well as the uplift rates of the model are consistent essentially with those of the prototype in nature;(2) the major driving force for intraplate tectonic deformation in central-eastern Asia results mainly from the compression of the Indian plate;(3) the existence of the RSBs, such as those of Tarim, Alxa, Ordos and Sichuan basin, is one of the basic origins for the development of large-scale compressional basins and the table-like uplift of the Qinghai-Tibet plateau;(4) The netlike plastic-flow in the lower lithosphere is faster than the displacement in the upper layer, controlling the tectonic stress and deformation fields in the upper crust;(5) the weakness layer distributed discontinuously in the middle crust influences the level of difference between the stress directions in the lower lithosphere and those in the seismogenic layer.

The relationships between large igneous rock province, mantle plume and petroleum show that there is a low velocity-high conductive layer of mid-crust in the basin and this layer is the main source of oil and gas. Weathered granites and volcanic rocks are the best reservoir beds for hydrocarbon accumulation and the faults are the main migration pathway. It is suggested that granite and volcanic reservoirs be the future exploration targets.
