9725570 Wiltschko The dynamics of fold and thrust belts has received considerable theoretical and field attention due to their role in collision and mountain-building. A leading model is based on the idea that a fold/thrust system maintains a specific wedge taper by deforming internally. Rigorous test of the wedge model requires data on the motion of thrust belt structures. This project takes advantage of the high rate of growth of the Taiwan arc-continent collision to study fold and thrust belt motion, principally by use of extensive GPS data. Results are expected to illuminate relative roles of folding and faulting both at the thrust front and across the belt, document the uplift and displacements of structures and to help discriminate and geodynamic models, including the wedge model for fold and thrust belts.

9725570由于褶皱和冲断带在碰撞和造山中的作用，褶皱和冲断带的动力学受到了相当大的理论和野外关注。领先的模型基于这样的想法，即褶皱/推覆系统通过内部变形来保持特定的楔形锥度。对楔形模型的严格测试需要有关逆冲带构造运动的数据。本项目利用台湾弧陆碰撞的高增长速率，主要利用大量的GPS资料研究褶皱冲断带的运动。预计结果将阐明在逆冲前缘和跨带的褶皱和断层的相对作用，记录构造的隆起和位移，并有助于区分不同的地球动力学模型，包括褶皱和逆冲带的楔形模型。
