The characteristics of elements shows that magma of fine dioritequartz diorites derived from the enriched mantle or lower crust undergone ocean crust subducting and dehydrating, and was formed and emplaced in the process of crust growth. The magma of dioritic porphyritedacitic porphyries emplaced relatively late, it might derive from upper crust or undergo intensive contamination of crustal materials, and was formed in the proces of crust thining. These characteristics suggest that the geodynamics background of the Jinchanggouliang gold deposit formation is the transition process from compression to extension.

元素地球化学特征显示：细晶闪长岩-石英闪长岩的岩浆源于富集地幔或洋壳俯冲脱水交代的下地壳，地壳增厚过程产生并就位；闪长玢岩-英安斑岩类的岩浆就位相对晚，来源具有上地壳性质或被地壳物质强烈混染，地壳减薄过程形成；这种特征暗示金厂沟梁金矿形成的地球动力学背景是在地壳挤压增厚转化为伸展减薄过程。

The Middle Proterozoic Caiziyuan peridotite was formed in the epicontinental basin at the ocean-land boundary or within-continent rift basin. Its mantle source could be metasomatized by the dehydration fluid of subducted plate, and much initial radioactive 〓Nd was added to the source.

The study indicates that the Pb and Zn ore-forming elements probably come from the basement rocks; The initial Pb isotope could be derived from the crust-mantle mixing in the erogenic belt; sulfur isotope composition is enriched in heavy sulfur that may have come from the seawater sulfate in the synchronous sedimentation; the ore is characterized with REE enrichment, obvious fractionation of LREE and flat-pattern of HREE; ore-forming media is thermal brine fluid; both mineralization temperature and pressure are low; the metallogenic epoch is probably in late Dengying epoch of Sinian period.

研究表明，基底岩系可能为成矿元素Pb、Zn的主要来源；原始铅主要来源于壳幔棍合的造山带；硫同位素富集重硫，可能主要来源海水硫酸盐；矿石中稀土元素富集，轻稀土分异较明显，而重稀土分异不明显；成矿流体推测为热卤水性质，成矿温度为中低温，具有低压浅成成矿特点；矿床形成的初期应始于震旦纪灯影世晚期。

If no cortical mantle is present, but a falx is noted, then this anomaly is most probably hydranencephaly.

如果未见脑皮质存在但见到大脑镰，那么这种异常最有可能是水脑畸形。

On the basis of lithosphere dynamics, it is possible to deduce whether the boundary fault cuts through the Moho into the upper mantle of the lithosphere or not, and it is also possible to get the distributions of the values of Te in the study area by gravity tomography. Therefore, it helps to further understand the deep lithospheric geodynamical features in this study area.

通过岩石圈动力学理论，不仅可以推断边界断裂是地壳断裂还是地幔断裂，而且可以通过重力反演得到该区岩石圈有效弹性厚度的分布特征，从而进一步了解该区深部岩石圈形变特征。

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。

This tendency is well correlated to the geotectonic features and the structure of the crust and upper mantle, and approximately coincident to the features of other geophysical field in this region.

并提出该区尤其是郯庐带的某些地段可能有上地幔物质上涌，引起地壳深部产生很大的温度差异和密度差异，造成热应力的高度集中。

The research works on the crust and upper mantle structure in Jiangsu province and its adjacent areas, that is divided into the southeastern Yangzi block, the southern segment of Tancheng-Lujiang fault zone, the eastern segment of Dabie orogen and the Sulu UHPM block according to geotectonics and research level, are introduced based on the results of different research methods such as deep seismic sounding, earthquake travel time tomography and other geophysical survey.
