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

该项目提供资金，用于国际旅行支持，约早期职业的专业人士和学生参加彭罗斯会议“变形，流体流动和质量传递沿着收敛边缘”，将在伊尔Ciocco，意大利，从2012年3月26日至30日举行。会议将探讨最近的发展有关的变形，流体流动，并在收敛板块边界的前弧质量转移和它们的潜在关系，地震现象和地震成因。会议的目的是巩固最近在会聚边缘的理解方面取得的进展，并汇集不同背景的研究人员，以开发弧前演化模型，解释在各种时空尺度上的几何形状，结构，变形和流体流动的观测。前弧也是在大海啸地震中发生能量释放的区域，但地震周期变形与长期地质结构，材料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：⑴物质平衡-增生和侵蚀的过程和速度及其对地震成因的影响; ⑵俯冲板块和覆盖板块之间的相互作用，包括大陆坡和弧前盆地; ⑶楔体动力学和地震时标与地质时标之间的联系; ⑷弧前流体流动：从岩石微结构和地球化学的直接观察和推断的证据;和（5）地震周期的时间尺度。本次会议讨论了许多当前在构造和相关领域的研究课题。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。这次会议提供了一个机会，整合陆上和海洋观测，力学和流体流动的实验，以及地球动力学模拟的结果，以评估这些过程之间的关系，板块边界地震成因和环太平洋地区的灾害-一个社会非常关注的话题，如2011年3月在日本北方的破坏性事件。召集人将努力通过支持学生和来自地球科学代表性不足群体的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.
