台湾造山带是晚新生代以来菲律宾海板块与欧亚板块汇聚的产物。在主干范围内观察到了极高的折返速率，这促使解释模型认为底侵作用是驱动隆升和增厚的主要过程。在这里，我们结合碎屑锆石的新的(U-Th)/He和裂变径迹年龄以及以前发表的热年代学，记录了台湾造山带核心的重大无序逆冲作用。该逆冲断层的非正式名称为泰林断裂系，通过构造运动学和偏移变质温度趋势、低温热年代学和地震层析成像进行识别。OOST似乎由三个部分组成，它们沿着主干山脉的西侧突起。表观年龄-高程剖面表明，在8~2 Ma的早期阶段，折返速率相对较慢，为1.0 mm/a，2 Ma后的折返速率明显较高，在2.3~6.5 mm/a之间。早期缓慢折返阶段与区域褶皱和面理发育有关。相反，我们认为较年轻的快速折返阶段与无序逆冲的滑脱有关。
The Taiwan orogenic belt results from convergence between the Philippine Sea plate and Eurasia plate since the late Cenozoic. An extremely high exhumation rate has been observed in the Backbone Range, which has motivated interpretive models that show underplating as the primary process in driving uplift and thickening. Here we integrate new (U-Th)/He and fission-track dates of detrital zircons with previously published thermochronology to document a significant out-of-sequence thrust in the core of Taiwan orogen. The thrust, informally named the Tayulin fault system, is identified by structural kinematics and offset metamorphic temperature trends, low-temperature thermochronometric dates, and seismic tomography. The OOST appears to be composed of three segments that crop out along the western flank of the Backbone Range. The apparent age-elevation profiles suggest a relatively slow exhumation rate, <1.0 mm/yr, in the early stages from 8 Ma to 2 Ma followed by a stage of significantly higher exhumation rates, ranging from 2.3 to 6.5 mm/yr after 2 Ma. The early slow exhumation stage is related to regional folding and foliation development. In contrast, we suggest the younger rapid exhumation stage is related to slip on the out-of-sequence thrust.
