9320204 Crespi Taiwan is considered a classic example of a steady- state fold-and-thrust belt in which accretion is balanced by erosions and is the basis for current collision models. The possible presence of a syn-orogenic normal fault therefore has more than local interest. This project will examine the Lishan Fault which separates two belts of relatively low metamorphic (but distinctly different) grade along the axis of the orogen. Thermal maturity of the wall rocks will be used todetermine both fault geometry and offset. Results should help understand the processes that contribute to the development of synorogenic normal faults in overall compressional environments.

小行星9320204 台湾被认为是一个典型的稳定状态的褶皱冲断带的例子，其中增生是平衡的侵蚀，是目前的碰撞模型的基础。 因此，同造山期正断层的可能存在不仅仅是当地的兴趣。 本项目将研究梨山断层，该断层沿着造山带轴线分隔两个变质程度相对较低（但明显不同）的带。 围岩的热成熟度将用于确定断层几何形状和偏移。 结果应有助于理解的过程，有助于发展同造山正断层在整体挤压环境。
