| 摘 要： | 本文首次提出新疆北山古生代大地构造属性为板内断裂造山带,具有下列基本特征:①造山带形成和发展受主断裂控制;②以成熟度低、分选差的陆源碎屑沉积为主;③岩浆活动有其本身的特点;④横向不均一性特征非常突出;⑤剖面结构构造特征,主要从造山带两侧分别向外缘逆冲,构成背冲型;⑥空间上由三个断裂造山带平行排列组合在一起;⑦时间上经历了三个断裂造山旋回。

| Abstract: | In the paper it is put forward for the first time that the paleozoic geotec-tonics in Beishan of Xinjiang belongs to an intraplate fracturing orogenic belt. It has the following basic characteristics: 1. the formation and evolution of orogenic belt are controlled by the main fractures ; 2. it is dominated by the terrigenous clastic sediment of low maturity and poor sorting; 3. the magma has its own evolution characteristics; 4. the transversal inhomogeneity is extremely distinct; 5.the structure in the section is mainly characterized by the thrusting from the two sides of orogenic belt to the outer margin; 6. it is composed of the three parallel fracturing orogenic belts; 7. it underwent three fracturing orogenic cycles. |
