9618661 Gieskes This award will support collection and analysis of piston cores from the transition zone between subduction and collision south of Taiwan, in order to evaluate sedimentologic processes and evidence of fluid advection during the early developmental stages of an active arc-continent collision. Field work will be completed as part of a joint project aboard a Taiwanese research vessel in which Taiwanese scientists are examining the texture and physical properties of margin sediments. The significance of this project lies in the value of constraining active sedimentary processes and fluid expulsion in modern, arc- continent collision to provide a model for use in examining such settings now incorporated into the continental record. additionally, this work will provided the regional geologic context within which to evaluate the results from deep sea drilling which has been proposed for the Taiwanese margin.

9618661 Gieskes该奖项将支持收集和分析台湾南部俯冲和碰撞之间过渡带的活塞岩心，以评估沉积过程和活跃弧-陆碰撞早期发展阶段的流体平流证据。实地工作将作为一个联合项目的一部分在一艘台湾研究船上完成，台湾科学家正在研究边缘沉积物的结构和物理特性。 该项目的意义在于，它对现代弧-陆碰撞中的活跃沉积过程和流体排出进行了限制，提供了一个模式，可用于研究现已纳入大陆记录的这种背景。 此外，这项工作将提供区域地质背景，在此背景下评估已提议在台湾边缘进行的深海钻探的结果。
