This project represents a collaborative seismic imaging program between geoscientists
of the United States and The Republic of China (ROC) to study orogenic processes
associated with the Taiwan arc-continent collision. Uplift rates measured along the
collision suture in southeastern Taiwan are among the fastest in the world. Little is
known about the crustal structure beneath this region or the mechanisms responsible for
uplift at the critical transition from subduction to collision located in the offshore
south and east of Taiwan. The US-ROC program will significantly increase understanding of
crustal deformation in critical regions of a modern orogenic belt, which has served as an
important model for the mechanics of fold-and thrust belts worldwide. This investigation
will provide the necessary regional information for ODP drilling proposed to study the
closure of a forearc basin during arc accretion to a continent.
