GPS Investigation of the Actively Deforming Fold and Thrust Belt of Taiwan

目前关于逆冲带中主动形成褶皱和断层的详细运动数据不足以在各种模型之间进行严格的测试，但这些数据很难获得。本项目将利用台湾弧-陆碰撞的高速生长性，从快速运动的逆冲锋面出发，研究逆冲褶皱带南段的逆冲褶皱带运动。GPS大地测量数据与广泛的地震和钻井数据相结合，有望产生活动褶皱和断层上的三维地面运动数据，新的平衡剖面，以及大地测量结果与标准地球物理震源和震源机制解决方案之间的校准。这些将在评估冲断带动力学的楔形模型中具有相当大的效用。

Present data on the detailed motions of actively forming folds and faults in thrust belts are inadequate to rigorously test between various models, but such data are difficult to obtain. This project will take advantage of the high rate of growth of the Taiwan arc-continent collision to study fold and thrust belt motion from the rapidly moving thrust front across the southern portion of the fold/thrust belt. GPS geodetic data combined with extensive seismic and drilling data are expected to result in three dimensional ground motion data over active folds and faults, new balanced sections and a calibration between geodetic results and standard geophysical hypocenter and focal mechanism solutions. These will be of considerable utility in evaluating the wedge model for thrust belt dynamics.
