9706801 Byrne The role of normal faulting in the exhumation of high-grade metamorphic rocks in convergent orogens is an important unsolved problem. Taiwan provides a valuable opportunity to study the relation between contraction and extension and the processes of tectonic exhumation because the orogenic belt is active, and because the obliquity of the collision also results in a time-space equivalence that permits different veins of the orogenic belt as it evolves. This project involves documentation of the distribution of contractional and extensional structures in southernmost Taiwan and testing of several proposed models. Results will be applicable to regional-scale tectonics of Taiwan and to other convergent margins.

小行星9706801 正断层在汇聚造山带高级变质岩折返过程中的作用是一个尚未解决的重要问题。 台湾提供了一个宝贵的机会来研究收缩和伸展之间的关系和构造折返的过程，因为造山带是活跃的，因为碰撞的相似性也导致了时空的等效性，允许造山带的不同纹理，因为它的演变。 本计画包括台湾最南端的收缩与伸展构造分布的资料，以及几个模型的测试。 结果将适用于台湾和其他会聚边缘的区域尺度的构造。
