Plate Boundary Structure and Deformation Workshop

该项目将支持夏威夷大学马诺阿分校为期两天的关于板块边界结构和裂谷和俯冲带变形的研讨会。研讨会的主要目标是展示和综合由NSF-GeoPRISMS（裂谷和俯冲边缘的地球动力学过程）项目资助的研究成果，这些研究成果与理解支撑汇聚和发散板块边界运动的构造过程有关。大约50名科学家将参加在夏威夷大学马诺阿分校的现场研讨会，其中至少23名将是早期职业科学家（学生，博士后，博士学位10年内的终身教职前教员）。该计划将包括主题演讲、海报和灯光演讲，以交流参与者进行的活跃科学的广度，以及讨论环节和早期职业发展的机会。还将为早期职业科学家举行为期半天的研讨会前会议。其目的是让代表所有五个地球地质系统重点站点的跨学科科学家小组参与进来，以鼓励新的合作。为了促进研究成果的综合和解决数据遗留问题，所有参与者将被要求开放其georisms数据集，并提供表明其位置的doi；这些将被编目和共享。研讨会组织者将采用蒙大拿州立大学的专业视频服务，制作约1分钟的外展视频，展示地质科学系统项目的科学发现；这些视频和主题演讲将在YouTube上发布。推进对板块构造理论的理解取决于对在收敛和发散板块边界作用的构造过程的研究。这些板块边界共同平衡了地球的岩石循环，塑造了我们的星球。该研讨会旨在将一组科学家聚集在一起，重点介绍由NSF地质系统资助的项目所确定的发现，这些项目包括裂谷形成和演化（RIE）和俯冲旋回和变形（SCD）计划。研讨会将主要解决与板块边界结构和变形过程相关的三个突出问题：(1)断裂带流变和变形之间的关系是什么，以及它们如何在野外和实验室的一系列时空尺度上受到约束？(2)地壳和地幔的流变学如何影响和/或记录板块边界的变形？(3)大尺度岩石圈过程、断裂带流变和地表过程之间存在怎样的反馈？研讨会将促进跨学科的互动，跨领域的研究专业知识（如地球化学、地质学、地球动力学、地震学、大地测量学、电磁等）和研究地点（即包括所有地球地质系统的重点地点），以解决有关基本构造过程的问题，并通过鼓励所有参与者的积极参与来激发未来的研究合作。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project will support a two-day workshop at the University of Hawaii at Manoa related to plate boundary structure and deformation at rifts and subduction zones. The primary goal of the workshop is to present and synthesize research results that have been funded by the NSF-GeoPRISMS (Geodynamic Processes at Rifting and Subducting Margins) Program related to understanding the tectonic processes that underpin movement at convergent and divergent plate boundaries. Approximately 50 scientists will participate in the workshop onsite at UH Manoa, of which at least 23 will be early-career scientists (student, postdoc, of pre-tenure faculty within 10 years of PhD). The program will consist of keynotes, posters, and lighting talks to communicate the breadth of active science conducted by participants, as well as discussion sessions and opportunities for early career development. There will also be a half-day pre-workshop meeting for early-career scientists. The aim is to have participation from an interdisciplinary group of scientists representing all five GeoPRISMS focus sites to encourage novel collaborations. To facilitate synthesizing research results and address data legacy targets, all participants will be required to make their GeoPRISMS datasets open-access and provide a doi indicating their location; these will be cataloged and shared. The workshop organizers will employ specialized video services from Montana State University to create ~ 1 minute outreach videos that capture scientific discoveries of the GeoPRISMS program; these and the keynote talks will be made available on YouTube.Advancing understanding of plate tectonic theory hinges on investigations of tectonic processes acting at both convergent and divergent plate boundaries. Together, these plate boundaries primarily balance Earth’s rock cycle and shape our planet. The workshop aims to bring a group of scientists together to highlight discoveries determined through NSF GeoPRISMS funded projects encompassing both the Rift Initiation and Evolution (RIE) and Subduction Cycles and Deformation (SCD) initiatives. The workshop will primarily tackle three outstanding questions associated with plate boundary structure and deformation processes: (1) What are the relationships between fault zone rheology and deformation and how are they constrained across a range of temporal and spatial scales in the field and lab? (2) How does the rheology of the crust and mantle influence and/or record deformation at plate boundaries? (3) What feedbacks exist between larger scale lithospheric processes, fault zone rheology, and surface processes? The workshop will facilitate interdisciplinary interactions that cross-cut research expertise (e.g. geochemistry, geology, geodynamics, seismology, geodesy, EM, etc.) and study locations (i.e. encompassing all GeoPRISMS focus sites) to address questions pertaining to fundamental tectonic processes and motivate future research collaborations by encouraging active participation from all participants.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
