After interpreting natural earthquakes since 1953,the author also did a exploratory research on the lithospheric tectonic relationship of South Tienshan orogen,and considered in west and east side,West Kunlun orogen and Tafim block,and considered that Tarim block subducts beneath the West Kunlun orogen and South Tienshan orogen in two direction;In Pamir area,a syntaxis formed with the West Kunlun orogen obducts upon the South Tienshan orogen,and result in the two great orogens that rejuvenated during Cenozoic and the subduction and jointing relationship of the two orogens and Tarim block,showing a specific basin-and-range coupling system.

5通过对天然地震剖面的解释，探索了南天山造山带、西昆仑造山带和塔里木地块的岩石圈大地构造关系，认为在东西两侧，塔里木地块为南北直接俯冲于西昆仑造山带和南天山造山带之下的双向俯冲模式；在中部地区，西昆仑造山带在帕米尔地区形成构造结并仰冲于南天山造山带的前陆冲断带之上，形成了两个新生代复活的巨型造山带，以及两大造山带与塔里木地块之间的俯冲和对接关系，形成了独特的&盆一山&耦合体系

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

In this paper, we introduce the controlled factors of weathering of granites and the characteristics of the major granite landscapes. The mechanism of these landscapes are outlined.

由于其不同大地构造背景，产生了不同的岩浆成分和结构构造以及不同的断裂型式(Pitcher，1983)；同时也由于所处的不同的气候环境，导致了花岗岩地貌具有不同的类型。

To study the deep faults of crust through geophysics not only provides proofs to further study of basic theories such as the crust evolution and continent formation, but also provides an important guidance to classifying tectonic units, analysing and predicting natural earthquake activities and studying different kinds of mineralisation.
