In order to verify the model mentioed above, the mathematical simulation of geotemperature field has been carried out. The thrust nappe sheat zones are handled with two ways: 1 they are treated as constant heat sources in terms of q=τμ, that is, the quantity of frictionally generated heat is constant; 2 as heat conduit with high thermal conductivities and with fluid flow in fault zones.

为了进一步检验上述逆冲推覆复合叠加构造模型的可信程度，开展了地温场数值模拟工作，按复合叠加型岩石圈热结构给定各种热物性参数，逆冲推覆剪切带以两种方式处理，一是把它作为定热源按q＝τU，即按摩擦生热量级大小取值；第2种是把它作为热通道处理。

Kinematics and geodynamic modeling of continental deformation, along with thermal-rheological structure of the continental lithosphere are all emphasized here for study in future.

所以，大陆动力学应注重开展大陆变形的运动学、大陆岩石圈的热－流变学结构和大陆变形的地球动力学数值模拟研究。

Deep lithospheric mantle in the Qinghai-Tibetan plateau and adjacent area, which consists of imbricated dipping-northward multi-lithospheric terrains, is in convergent-subduction regime for sinking of cold lithospheric material. Geoidal anomalies and P/S velocity tomographies show that subduction into beneath Euro-Asian continent by Indian lithosphere not only causes intensive crustal upwelling, thickening and shorting deformation along S-N, but also affects depth of～600km in the plateau and eastern part of the Chinese continent and southern margin of the Siberian block.

大地水准面异常和P/S速度层析成像显示，印度大陆岩石圈向欧亚大陆的俯冲作用，不只是引起地壳的强烈加厚、隆升和南北向缩短变形，纵向上影响到600km深度，横向上波及到了中国东部和西伯利亚南部。

Special shape and distributing feature of Xinjiang geomorphy reflect change of deep material motion of crust and lithosphere.

新疆独有的地貌形态及展布特征反映了地壳－岩石圈深部物质运移变化的结果。

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。

Crustobody-A New Concept of Integrative Geotectonics;2. And its tectonic evolution and dynamic model of the northwestern crustobody of the South China Sea is preliminarily discussed.

本文根据南海西北部壳体的地形地貌、重磁场异常和地壳结构特征和岩石圈动力学环境，对穿过莺歌海盆地和西沙海槽的地震剖面进行解释。

The lower degrees of mantle melting of the HT and LT2 lavas may be the result of a relatively thicker lithosphere and lower geotherm.

HT和LT2熔岩的地幔熔融程度较低，可能是与地幔柱边部的岩石圈相对较厚和地热较低有关。

The main tectonic features of the four stages mentioned above can be summarized as follows, gneissic basement and greenstone belt in the Archean, formation and rifting of ancient continental crust in the Transition, creation and disposal of the first supercontinent Columbia in the Paleoproterozoic-Mesoproterozoic, and the assembly and disassembly of the supercontinent Rodinea under plate tectonic framework in Neoproterozoic.

这四大阶段的主要构造面貌分别是：片麻岩基底和绿岩带盆地，古陆壳的形成与裂解，第一个超级大陆即哥伦比亚超大陆的形成与离散，板块构造体制下罗迪尼亚超大陆的汇聚与离散，反映了大陆岩石圈的形成和由低级向高级的演化，因而每一阶段都有不同于前一阶段的沉积建造、火成岩类型及组合、变质作用、构造样式、构造线方向、变形方式和成矿作用。

This is an A_1 type granitoid belt, slightly predominated by mantle components. Their source regions are probably mainly the lithospheric mantle and lower crust, which had been metasomatized and enriched so that they could bear OIB characters in trace elements.

这是一个以地幔物质略占优势的A1亚型花岗质杂岩带，其源区物质可能主要是经过交代和富集的具有OIB型微量元素特征的岩石圈地幔和下地壳。

It was also indicated by the temperature calculation that the lithspheric mantle is stratigraphically layered with the lower part composed by fertile lherzolite and the upper part by refractory harzburgite and clinopyroxene-poor lherzolite.

Sr-Nd-Hf同位素资料反映这些地幔包体均表现为亏损性质，而Re-Os同位素资料确定上述岩石圈地幔形成于中元古代，明显老于上覆地壳的新元古宙时代，反映壳幔年龄上的解耦。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
