摘要
以板块构造观点讨论了构造单元的划分原则.研究区包括西伯利亚、哈萨克斯坦-准噶尔和塔里木三大板块,以哈萨克斯坦-准噶尔板块为主体.该板块进一步划分为两个微板块,东北为巴尔喀什-准噶尔微板块,以古生代洋盆为主体,古老陆壳残片少量;西南称科克切塔夫-伊塞克-伊犁-中天山微板块,以古老的陆壳基底为主体,古生代洋盆次之.在此基础上对各微板块作了进一步划分,对各次级单元主要特征分别进行了描述.
Based on the view of plate tectonics, this paper discussed the division of tectonic units in principle. The research region include three plates Siberia plate Kazakstan-Junggar plate and Tarim plate. The Kazakstan-Jtmgar plate as a main part is further divided into two sub-plates, Balkhash-Junggar sub-plate in the northeast appear mainly in palaeozoic ocean basin and partly in palaeo-continent remnants ;The Kekqitave-Yisek-Yily-Middle Tianshan sub-plate in southwest appear mainly in palaeo-continent basement, and secondarily in palaeozoic ocean basin. Each sub-plate is further divided. The features of each sub-unit are described respectively.
