The island of Taiwan is undergoing active deformation and uplift as a result of subduction of the Philippine Sea plate under the Eurasian plate, and provides a natural laboratory to study the kinematics of collision. This project will focus on the kinematic history of the hinterland region of central Taiwan, taking advantage of the southward propagation of the arc-continent collision to proxy sequential development of deformation features. A variety of strain and kinematic indicators will be studied and the results will be applied to several major hypotheses of collision tectonics including whether the hinterland is shortening with a consistent transport direction or involves two oppositely verging transport directions and the relative importance of tectonic denudation and erosion during unroofing of the hinterland.

由于菲律宾海板块俯冲到欧亚板块之下，台湾岛正在经历活跃的变形和隆起，为研究碰撞运动学提供了一个天然的实验室。 本计划将重点研究台湾中部腹地地区的运动史，利用弧大陆碰撞的向南传播来代理变形特征的顺序发展。 将研究各种应变和运动学指标，并将结果应用于碰撞构造的几个主要假设，包括腹地是否以一致的搬运方向缩短或涉及两个相反的边缘搬运方向，以及腹地揭顶过程中构造剥蚀和侵蚀的相对重要性。
