0530977FurlongThis Planning Workshop is focused on a transpressional plate boundary with the goals of: 1) examining why transpression results in contrasting styles of plate-boundary deformation (subduction versus transform faulting) in adjacent segments of the plate boundary; and 2) delineating the nature of the transition between these two regions. The proposed study area, the Fiordland - Southern Alps region of New Zealand, appears to provide an outstanding example of contrasting transpressional behavior, as well as being a region where a large amount of related studies (with substantial NSF - EAR funding) have already been completed or are underway. However, most of the projects in NZ have focused on local segments of the plate boundary, aiming at testing specific processes or tectonic models applicable to that segment. With the exception of one well known review paper (Walcott - 1998) there are essentially no attempts to link together our understanding of the plate boundary segments into a lithospheric scale picture of how the plate boundary as a whole works. For these reasons, the PIs will host a Science Planning Workshop focused on the plate boundary geodynamics of New Zealand. The "output" of the workshop will be a Science Plan for plate boundary research in South Island, New Zealand. The Workshop will bring together a group of researchers from the U.S., NZ, and other countries, who have focused on various aspects of the NZ plate boundary system to both hash out issues in the current understanding and identify the first order questions that remain and thus could help drive the next generation of plate boundary research. The Science Plan could help focus research projects, make the links among disparate experiments, provide background information to plate boundary researchers less familiar with the NZ system - but with substantial insight from their research on other plate boundary systems, and provide the basis for new integrative multi-disciplinary projects. The Plan will also serve the research funding agencies , NSF and the NZ-FRST (Foundation for Research Science and Technology) in their planning.

0530977弗隆本次规划研讨会的重点是扭压板块边界，其目标是：1）研究为什么扭压导致板块边界相邻部分的板块边界变形（俯冲与转换断层）的对比风格; 2）描绘这两个区域之间过渡的性质。 拟议的研究区域，峡湾-南阿尔卑斯山地区的新西兰，似乎提供了一个突出的例子，对比transpressional行为，以及作为一个地区，大量的相关研究（与大量的NSF -基金会的资金）已经完成或正在进行中。 然而，新西兰的大多数项目都集中在板块边界的局部部分，旨在测试适用于该部分的特定过程或构造模型。 除了一篇著名的综述论文（Walcott - 1998）之外，基本上没有尝试将我们对板块边界段的理解联系起来，形成一幅关于板块边界如何作为一个整体起作用的岩石圈尺度图。 由于这些原因，PI将主办一个科学规划研讨会，重点是新西兰的板块边界地球动力学。 讲习班的“产出”将是新西兰南岛板块边界研究的科学计划。 研讨会将汇集一组来自美国的研究人员，新西兰和其他国家，他们专注于新西兰板块边界系统的各个方面，以解决目前理解中的问题，并确定仍然存在的一阶问题，从而有助于推动下一代板块边界研究。 科学计划可以帮助集中研究项目，使不同的实验之间的联系，提供背景信息，板块边界研究人员不熟悉新西兰系统，但从他们的研究对其他板块边界系统的实质性见解，并提供新的综合多学科项目的基础。 该计划还将为研究资助机构、NSF和NZ-FRST（研究科学和技术基金会）的规划提供服务。
