Workshop Support: 4-D Framework of Continental Crust

2004年7月，在田纳西州橡树岭举行了为期四天的题为“大陆地壳的四维框架--随时间整合过程”的国际研讨会和会议。广泛的多学科专题包括：形成陆壳的物理和化学过程的时间变化；深部和浅部地壳的形成过程及其时间变化；莫霍面的演化；流体相互作用过程；岩浆的产生和侵位过程/模型；变质过程；导致新大陆壳的变形过程；驱动地壳流变变化的过程；造山过程；超大陆形成；地壳演化中的沉积过程；生物系统在地壳演化中的作用。研究生、年轻的和职业生涯中期的科学家和高级研究人员正在参加旨在引起讨论和辩论的半正式的应邀和自愿的演讲。报告强调过程、概念、由最先进的数据支持的新想法，以及未来的研究方向。闭幕会议将讨论地壳科学的前沿领域、地球望远镜为了解地壳演化提供的未来机会，以及通过信息技术促进地球科学的发现。为期五天的会议后短途旅行将穿越阿巴拉契亚山脉南部。正在出版一份简短的白皮书，概述目前和未来可能进行的最先进的地壳地球科学研究，并出版会议论文集。

A four-day international workshop and conference titled "The Four-Dimensional Framework of Continental Crust - Integrating Processes Through Time" is being held in Oak Ridge, Tennessee in July of 2004. Broad multidisciplinary topics being addressed include: temporal variation in physical and chemical processes that generate continental crust; processes of deep and shallow crust generation and their temporal variation; evolution of the Moho; fluid interaction processes; magma generation and emplacement processes/models; metamorphic processes; deformational processes leading to new continental crust; processes driving crustal rheological changes; mountain building processes; supercontinent formation; sedimentary processes in crustal evolution; role of biological systems in crustal evolution. Graduate students, young and mid-career scientists, and senior researchers are attending semiformal invited and volunteered presentations intended to generate discussion and debate. Presentations emphasize processes, concepts, new ideas supported by state-of-the-art data, and future research directions. The closing session is addressing frontiers in crustal science, future opportunities from EarthScope for understanding crustal evolution, and nuturing geoscience discovery through information technology. A five-day post-conference excursion is traversing the southern Appalachian Mountains. A short white paper summarizing current and possible future state-of-the-art crustal geoscience research and a proceedings volume are being published.
