And combined with the transformation of the basin-basin and basin-mountain formed by Caledonian movement, the author thinks that,(1)the Yangtze and Huaxia are still the different plates in Caledonian period, Yangtze plate is subduction plate, Huaxia plate is obduction plate by the activation of PreSinian period tectonic plate joint belt.
首先,虽然有古地磁资料表明两地块从震旦纪到奥陶纪是逐渐靠拢并拼接在一起的,但华南地区至今没有找到证实这次碰撞结合的含有加里东洋壳残片在内的蛇绿岩混杂带,也没有发现与之有关的沟弧盆体系,对此有着不同的解释,这也是研究区多年来一直困扰许多地质学家的原因,也是大家一直争论的热点。

In view of an analysis from lithospheric geoid, horizontal stress and existing seismic tomographic data and so on, they show that Chinese mainland and adjacent area is controlled by mantle dynamics of interaction, mutual influence and constraint by western Pacific ocean plate, Indian plate and circum-Siberian arc tectonics that formed after Paleo-Asian ocean closed, which consist of three tectonic areas, with on the base of the Tethyan tectonic realm. Overall tectonic framework of the Chinese mainland is outwards obduction along main tectonic borders within shallow crust and inwards subduction and convergence within deep lithospheric mantle from south-western, south-eastern and northern parts, respectively.
基于岩石圈大地水准面异常、水平应力场和地震层析等地球物理资料综合分析可知,中国大陆及其毗邻地区在特提斯构造基础上,处于西太平洋板块、印度板块和古亚洲洋及其闭合之后环西伯利亚弧形等三大全球构造体系域相互作用、相互影响和相互制约的地幔动力学控制之下,总体大地构造格局是浅部地壳分别沿主要构造边界向外仰冲,深部岩石圈地幔则从西南、东南和北部向中国大陆俯冲会聚,使之整体处于地幔会聚挤压的大地构造背景。

Not only is the present Yangtze craton constrained by regional compressional stress field but also its cold and dense lithospheric root is descended into the deep mantle by negative buoyancy, Which further strengthens inward obduction of orogenic belts surrounding it. For examples, Longmen shan mountain, Huaying shan and Bamian shan mountains override onto western margin and eastern part of Sichuan basin, respectively.
现今的扬子克拉通不仅受大区域挤压应力场背景制约,同时其冷而致密的巨厚岩石圈根正在向深部地幔下拽,从而进一步加剧了四周造山带向盆地的逆冲作用,龙门山、华蓥山和八面山分别向川西盆地和川东逆冲就是例证。

Among above deformation, the thrust-fold structure formed in Triassic established the E-W trend framework controlling the distribution of the late compressive settling. The NNE-NE trend obduction zone and regional folds is contributed to effect of Tethys tectonic region superimposed by Paleo-Pacific tectonic region.
其中三叠纪挤压变形产生的冲断—褶皱构造,奠定了本区中生代近东西向构造格局,并控制后期挤压坳陷型盆地的的空间展布规律;晚侏罗世早期挤压形成的北北东—北东向逆冲推覆构造带和区域性褶皱是特提斯构造域与古太平洋构造域共同叠加的结果。

Hechi-Yishan fault zone is located in the north of Guizhong depression, which general strike is NW-EW and consists of a series of obduction fault. Generally, there are two main faults, the fault-fold belt about 5-20km is made of main faults, subsidiary faults and concomitant folds; The dip of main faults is N or S; It can be divided into four different structural sections along its strike (Hechi section, Yishan section, Liucheng section and Yingshan section). There are some differences among these sections in structure characteristic, such as fault structure, associated structure, fold association style, deformation of rock, and so on.
