| Study on the Reconstruction of Mesozoic–Cenozoic Paleoelevation in the Western Tianshan |
| The Tianshan mountain is located in the middle part of the Central Asian orogenic belt, stretching for nearly 2 500 km from the east to the west as a whole. The formation of the modern Tianshan is not only directly related to the plate subduction and collision orogenesis in Paleozoic, but also influenced by the far-distance effect of Indian-Asian collision in Ceno-zoic. The Cenozoic uplift and exhumation history of the Tianshan Mountain can help us to study the kine-matic and dynamic processes of orogenic belt inside Asian continent. In order to better understand how and when the topography of modern Tianshan was build, this study on reconstruction of paleoelevation in Sikeshu drainage basin, Tuoyun basin, north and mid-dle part of west Tianshan. In addition, from the study of structure deformation and sedimentation in fore-land basin, we discuss the the history of the Meso-zoic-Cenozoic paleoelevation in different parts of west Tianshan mountion. |
