摘要: 由地质、地球物理综合研究表明, 天山构造带具有复杂的深浅构造关系。以纳伦-那拉提-红柳河构造缝合带为轴, 天山南北两侧构造表现出明显的对称性, 在纵向上, 则表现出上、下硬、中间软的“三明治”式独特的圈层结构。在南北向构造挤压作用下, 天山南侧显示塔里木板块向北作陆内俯冲, 与天山地壳岩石圈发生层间插入与拆沉作用,在山前, 基底卷入盖层变形; 天山北侧准噶尔板块向天山挤入, 发生构造挠曲, 并形成山前深坳陷。天山南北两侧表现出不同的盆山耦合特征。

Abstract: Tianshan mountain tectonic belt is of a complicated relationship between the deep and shallow structures indicated by the synthetic researches in geology and geophysics. The structures on the south and north sides of Tianshan display obvious symmetry with the axis of Nalun-Nalati-Hongliuhe tectonic suture belt, and it vertically appears in particular spherical structure like a "sandwich" with rigidity in the top and bottom and the weak in the middle. On the south side of it, it appears that Tarim plate subducts northward intracontinentally, being interbedded to and detached with the lithosphere in Tianshan; in the piedmont Tianshan, the basement is entangled into cap rocks or covers and then deformed. On the north side, Junggar plate enters into Tianshan and has fluxion structures followed by shaping deep piedmont depressions. Therefore, the basin-mountain coupling feature is quite different in the south and north sides of Tianshan mountain.

Key words: Tianshan mountain, deep-shallow structure, basin-mountain coupling
