This thesis studies each structural layer ' s feature : ( 1 ) structural layer of basement : it is a paleozoic folded basement , whose tectonic deformation and magma intrusion is fiercely , and it is affected by the early hercynian tectonic movement and related to the underthrust and closure ( c1 ) of zhungaer ocean basin and the areal pressing of continents ( c2 - 3 ) ; ( 2 ) structural layer of permian : due to the regional extending and fault depression role in mid - hercynian , it occurred to the combinations of structure and magma in santanghu basin and it ' s periphery area , such as a - granite ' s stock , batholiths and diabase ' s dike . there are many fault depressions possible 按照不同构造层，研究了各构造层的构造特征：基底构造层：受早海西期构造作用的影响，与准噶尔洋盆俯冲闭合、而后陆-陆碰撞的区域挤压构造作用有关，为一构造变形和岩浆侵入活动强烈的古生代褶皱基底。二叠系构造层：受中海西区域性伸展断陷作用的影响，盆地及其周缘地区发育与伸展构造有关的构造-岩浆组合，如呈岩株、岩基状侵位的a型花岗岩以及呈岩墙状侵位的辉绿岩等。
