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

目前关于冲断带中活动形成的褶皱和断层的详细运动的数据不足以在各种模型之间进行严格的检验，但这些数据很难获得。 本计画将利用台湾弧-陆碰撞的高成长率，研究由快速移动的冲断前缘穿越褶皱冲断带南部的褶皱冲断带运动。 全球定位系统大地测量数据与广泛的地震和钻井数据相结合，预计将产生活动褶皱和断层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之间的校准。 这些将是相当实用的评价楔模型的冲断带动力学。

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.
