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.

该项目为美国的早期职业专业人士和学生提供旅行和注册支持，以参加戈登研究会议“岩石变形中的反馈过程”，该会议将于2012年8月19日至24日在新罕布什尔州安多弗举行。岩石变形会议系列突出了脆性和韧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。广泛的目标是评估的性质和岩石强度，断裂，摩擦，韧性变形，流体和熔体流动在自然构造加载过程中的控制的理解。这次会议的重点是反馈机制，这是非常重要的控制速率和机制的岩石变形。正反馈导致加速速率，并且通常导致空间聚焦，而负反馈通常导致减速，空间分布的变形和反应。本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、地震和断裂;（3）反应驱动破裂;（4）局部流体输运（涉及化学反应的反馈;机械反馈）;地震的动力学触发。本次会议讨论了构造学、地球物理学及相关领域的许多前沿研究课题。会议主题与非常规碳氢化合物资源的开采、加强地热系统的实施、地质碳捕获和储存以及了解地震灾害特别相关。该会议将促进学生、早期职业科学家和来自地球科学领域代表性不足群体的研究人员的参与。
