2012 Rock Deformation Gordon Research Conference: Feedback Processes in Rock Deformation

该项目为在美国工作的早期专业人士和学生提供旅行和注册支持，以参加将于2012年8月19-24日在华盛顿州安多弗举行的戈登研究会议“岩石变形中的反馈过程”。岩石变形会议系列突出了脆性和延性岩石力学的最新研究和未来趋势，包括实验、现场和理论贡献。其主要目标是评估在自然构造加载期间对岩石强度、破裂、摩擦、延性变形以及流体和熔体流动的性质和控制的了解。这次特别会议的重点是反馈机制，这在控制岩石变形的速度和机制方面非常重要。正反馈导致速度加快，通常导致空间聚焦，而负反馈通常导致减速、空间分布的变形和反应。这次会议的主要议题包括：(1)高围压下地质材料的破坏机制；(2)流体辅助滑动、地震和破裂；(3)反应驱动的破裂；(4)局部流体传输(涉及化学反应的反馈；机械反馈)；(5)地震的动态触发。会议涉及构造学、地球物理及其相关领域的许多前沿研究课题。会议主题对于开采非常规碳氢化合物资源、实施强化地热系统、地质碳捕获和封存以及了解地震灾害具有特别重要的意义。这次会议将促进学生、早期职业科学家和来自地球科学中代表性不足群体的研究人员的参与。

This project provides funding for travel and registration support to U.S. based early-career professionals and students to attend the Gordon Research Conference " Feedback Processes in Rock Deformation", which will be held in Andover, NH from August 19-24, 2012. The Rock Deformation conference series highlights the latest research and future trends in brittle and ductile rock mechanics, with experimental, field and theoretical contributions. The broad goals are to assess the understanding of the nature and controls on rock strength, fracture, friction, ductile deformation, and both fluid and melt flow during natural tectonic loading. This particular conference focuses on feedback mechanisms, which are very important in controlling the rates and mechanisms of rock deformation. Positive feedbacks lead to accelerating rates, and commonly to spatial focusing whereas negative feedbacks commonly cause decelerating, spatially distributed deformation and reaction. Major topics addressed at this conference include: (1) mechanisms of failure in geological materials at high confining pressure; (2) fluid-assisted slip, earthquakes and fracture; (3) reaction-driven cracking; (4) localized fluid transport (feedbacks involving chemical reaction; mechanical feedbacks); and (5) dynamic triggering of earthquakes.This conference addresses many cutting-edge frontier research topics in tectonics, geophysics, and related fields. The conference theme has special relevance for extraction of unconventional hydrocarbon resources, implementation of enhanced geothermal systems, geological carbon capture and storage, and understanding seismic hazards. The conference would promote the participation of students, early career scientists, and researchers from underrepresented groups in the earth sciences.
