Workshop Support: 4-D Framework of Continental Crust

2004年7月，一个为期四天的国际研讨会和会议在田纳西州的橡树岭举行，主题是“大陆地壳的四维框架-时间整合过程”。正在讨论的广泛的多学科主题包括：产生大陆地壳的物理和化学过程的时间变化；深、浅地壳生成过程及其时间变化；莫霍人的演变；流体相互作用过程；岩浆生成和侵位过程/模式；变质过程;形成新大陆地壳的变形过程；驱动地壳流变变化的过程；造山过程；超大陆的形成;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、年轻和处于职业生涯中期的科学家以及高级研究人员参加了半正式的邀请和自愿演讲，旨在引发讨论和辩论。报告强调过程、概念、最新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、EarthScope对了解地壳演化的未来机遇，以及通过信息技术促进地球科学的发现。会后为期五天的短途旅行将穿越阿巴拉契亚山脉南部。一份简短的白皮书总结了当前和未来可能的最先进的地壳地球科学研究，并出版了论文集。

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.
