COLLABORATIVE RESEARCH: The Transition Between the Fore- land and Hinterland in an Active Mountain Belt, Taiwan

台湾代表了一次活跃的弧陆碰撞，并在标志着碰撞的前陆和腹地之间的过渡带的板岩带内显示了许多中到微尺度的构造、增量应变历史和岩石体积变化。台湾碰撞带由北向南传播，提供了一种时空对等，可以用来记录特定构造事件的演化。与8904989(宾夕法尼亚州立大学的费舍尔)合作的这一项目的方法是检查沿山脉带走向的不同位置的几个交叉走向截面处的细观和微观结构、应变指标和岩石体积变化。对过渡带的这些综合研究的结果有望增进对碰撞山带的理解，特别是这种造山带的前陆和腹地之间的过渡。

Taiwan represents an active arc-continent collision, and displays a number of mesoscale-to microscale structures, incre- mental strain histories and changes in rock volume within a slate belt that marks the transitional zone between the foreland and hinterland parts of the collision. The Taiwan collision zone propagates from north to south, providing a time-space equivalence that can be used to document the evolution of specific structural events. The approach of this collaborative project with 8904989 (Fisher at Penn State) is to examine meso- and micro-structures, strain indicators and rock volume changes along several cross-strike transects at different positions along the strike of the mountain belt. Results of these integrated studies of the transition zone are expected to improve understanding of collisional mountain belts, particularly the transition between foreland and hinterland parts of such orogens.
