9805340 Yin The Tibetan plateau is one of several large areas of anomalously high elevation and is clearly related to collisional tectonics. Yet the actual timing and mechanisms of uplift is unclear. This project will examine whether or not old suture zones in the plateau have been reactivated, and if so, the timing and magnitude of the displacement. Results should clarify the shortening history of the plateau that may be hidden or obscured by suture reactivation, this allowing a more robust understanding of plateau uplift in orogenic zones.

然而，隆起的实际时间和机制尚不清楚。该项目将检查高原上的旧缝合带是否被重新激活，如果是，位移的时间和大小。研究结果应阐明可能被缝合线重新激活所隐藏或掩盖的高原缩短历史，从而对造山带的高原隆升有更有力的了解。
