The formation of the Tianshan tectonic belt is generally interpreted as a consequence of intra-plate compression and uplifting of a Paleozoic orogen belt induced by the remote effect of the Euro-Asian and Indian Plates during the Cenozoic Era (Shu et al. 2003;Yin et al. 1998). Several geological evidences , such as unconformities, have been used to establish the uprising history of the Tianshan tectonic belt, which divided the tectonic evolution into one uprising period and two erosion periods, i.e. the TrassicJurassic and the Late Cretaceous erosion and the Late Jurassic-Early Cretaceous uprising period (Zhang et al. 1985;Ma et al. 1993). The AFT studies reveal that the southwestern Tianshan experienced two rapid uprising periods at Early Cretaceous (134-109 Ma) and Miocene (17-25 Ma) (Yang et al. 1995; Yang et al. 2003; Wang et al. 2001). The uprising of the modern Tianshan began as early as 24 Ma ago (Hendrix et al., 1994; Sobel et al.,1997;Trevor, et al., 2001). Sedimentary analysis suggests a rapid uprising event of the Tianshan during the Late Pliocene and the Early Quaternary (Wang et al. 2000). The sedimentary sequences in the fore-land basins also provide some important clues of the tectonic evolution of the Tianshan tectonic belt(Yin et al., 1998; Yang et al.,1995;Jia et al.,2003;Li et al.,2003; Hendrix et al., 1992).
