GSA Penrose Conference on "Deformation, Fluid Flow and Mass Transfer along Convergent Margins"

该项目为参加将于2012年3月26日至30日在意大利伊乔科举行的“变形、流体流动和质量传递”彭罗斯会议的早期职业专家和学生提供国际旅行资助。会议将探讨最近在会聚板块边界前弧的变形、流体流动和传质方面的进展，以及它们与地震现象和地震发生的潜在关系。会议的目的是巩固对收敛边缘理解的最新进展，并将不同背景的研究人员聚集在一起，开发弧前演化模型，以解释在各种时空尺度上对几何、结构、变形和流体流动的观察。前弧也是大海啸地震中能量释放的区域，但地震周期变形与长期地质结构、物质性质和流体状态之间的联系仍然不清楚。会议的主要议题将包括：(1)物质平衡——增生和侵蚀的过程和速率及其对地震发生的影响；(2)俯冲和上覆板块（包括大陆斜坡和弧前盆地）的相互作用；(3)楔形动力学及其地震和地质时间尺度之间的联系；(4)弧前流体流动：直接观测证据及岩石微观结构和地球化学推断；(5)地震周期的时间尺度。本次会议讨论了当前构造学及相关领域的许多研究课题。会议为国际参与者提供了分享最新研究成果和建立新的国际研究伙伴关系的机会。会议提供了一个整合陆上和海洋观测、力学和流体流动实验以及地球动力学模拟结果的机会，以评估板块边界地震发生过程与环太平洋地区灾害之间的关系——这是一个备受社会关注的话题，2011年3月日本北部发生的破坏性事件就是例证。召集人将努力通过支持来自地球科学领域代表性不足群体的学生和早期职业研究人员来扩大参与。

This project provides funding for international travel support to approximately early-career professionals and students to attend the Penrose Conference "Deformation, Fluid Flow and Mass Transfer along Convergent Margins" that will be held in Il Ciocco, Italy, from March, 26-30, 2012. The conference will explore recent developments related to deformation, fluid flow, and mass transfer in the forearc of convergent plate boundaries and their potential relationships to earthquake phenomena and seismogenesis. The objective of the conference is to consolidate recent advances in the understanding of convergent margins and to bring together researchers of different backgrounds to develop models for forearc evolution that explains observations of geometry, structure, deformation, and fluid flow at a variety of temporal and spatial scales. Forearcs are also the regions where energy release occurs in great tsunamigenic earthquakes, yet the links between earthquake-cycle deformation and longer-term geological structure, material properties, and the fluid regime remain obscure. The main topics at the meeting will include: (1) material balances - the processes and rates of accretion and erosion and their influence on seismogenesis; (2) interactions between the subducting and overriding plates including continental slope and forearc basins; (3) wedge dynamics and links between seismic and geologic time scales; (4) fluid flow in the forearc: evidence from direct observations and inferences from rock microstructures and geochemistry; and (5) the timescales of the earthquake cycle.This conference addresses many current research topics in tectonics and related fields. The conference affords international participants the opportunity to share recent research results and initiate new international research partnerships. The meeting provides an opportunity for integration of onshore and marine observations, experiments on mechanics and fluid flow, and results of geodynamic modeling to evaluate the relationship between these processes for plate boundary seismogenesis and hazards of the Pacific Rim - a topic of great concern for society as exemplified by the destructive event in northern Japan in March, 2011. Conveners will make efforts to broaden participation through support students and early career researchers from underrepresented groups in the earth sciences.
