摘要
反天山构造带是一组线性构造及异常地貌的组合体，它具有极强的“穿透性”，独立于天山古生代构造格局之外，又可以叠加在不同的构造单元之上，为新生的上叠构造，而不是继承性构造；其成因与深部地幔物质的不均一性及相关的运动状态有关，主要成生时限为早二叠世至早、中三叠世；反天山构造带有较好的控矿作用。
Anti-Tianshan structural. zone is an assemble of linear structures and abnormal landforms. It could be superimposed on different structural units as the new-born superimposed structtire with powerful penetrability but not posthumous structure, free from the Tianshan Palaeozoic tectonic framework. It resulted from the inhomogeneity and motion of upper mantle. Anti-Tianshan structural zone was formed in the period of P1-T1-2 , controlling the distribution of ores.
