US-Egypt Workshop: U.S. Participation in Project JEBEL Workshop; Sharm El-Sheikh, Egypt, October 2008

0821257 SternDescription：该奖项旨在支持美国参与？美国-埃及北阿拉伯-努比亚盾构项目研讨会，将于2008年10月在埃及沙姆沙伊赫举行。美国组织者是达拉斯德克萨斯大学岩石圈研究中心的罗伯特·斯特恩博士。埃及的组织者是埃及开罗国家研究中心的奥萨马·卡西姆博士。JEBEL（约旦和埃及地下室演变）项目由瑞典政府通过向斯德哥尔摩大学的Vicky Pease教授提供赠款资助，为期三年。它是2007年2月在埃及举行的规划研讨会的成果，来自8个不同国家的科学家参加了该研讨会。瑞典的资助只涵盖瑞典、埃及和约旦参与者的研究和旅行，而美国、沙特、挪威和德国的科学家则在各自的国家获得资助。该奖项将支持四名美国科学家参加这一新的国际研究工作的两个实地研究和规划讲习班。第一次讲习班将于2008年10月在埃及举行，第二次讲习班将于2009-2010年冬季在约旦举行。这两个研讨会将讨论迄今为止的研究成果，并讨论未来的研究重点。在西奈半岛南部的关键地质地点进行为期四天的实地考察和讨论，同时进行一天的研究报告和规划。由于美国的参与对2007年研讨会的成功至关重要，对JEBEL项目的成功也将至关重要，瑞典和美国双方都希望继续派遣美国科学家？参与这项工作，这应该导致一个补充的国家科学基金会的努力。知识价值：JEBEL项目侧重于四个挑战：1)通过地质年代学、地球化学、地层学和构造研究，了解约旦、埃及东部沙漠（EDE），特别是埃及东部沙漠中部的新元古代演化；2)促进红海地区的地质关联、经济区外推，并限制红海地区的生态重建；3)对比新元古代造山带内的新元古代地体与古地理；4)有助于认识新元古代地球环境的发展。这些结果将有助于根据地质标志估计红海的总偏移量。阿拉伯-努比亚地盾的北部是延伸整个非洲大陆的主要泛非造山带中研究最少的部分之一，这些讲习班将把国际注意力集中在该地区。两位美国资深科学家，斯特恩博士和彼得·约翰逊博士（JV Associates Ltd.的），由于他们在该地区的丰富经验，将提供重要的投入。更广泛的影响：斯特恩博士的现任（Kamal Ali）和前任（Mohamed Abdelsalam博士）博士生的参与将带来相当大的好处，并满足支持早期职业研究人员的目标。美国团队的参与可能会导致美国科学家在一个发展中的欧盟-埃及-约旦计划的研究工作中建立新的伙伴关系，可能会提供有关该地区地质的重要信息。由于斯特恩博士为这个项目建立了一个网站：http://www.utdallas.edu/~rjstern/egypt/，讲习班和研究论文的结果有望得到广泛传播。在讲习班上所作的观察将在这个更广泛的场所用于虚拟实地指南，并使其他调查人员能够获得观察结果。该项目得到国际科学与工程办公室和地球科学司的支持。

0821257 SternDescription: This award is to support U.S. Participation in a ?US-Egypt Workshop on Northern Arabian-Nubia Shield-Project JEBEL?, to be held in Sharm el-Sheikh, Egypt in October 2008. The US organizer is Dr. Robert Stern, Center for Lithospheric Studies, University of Texas at Dallas. The Egyptian organizer is Dr. Osama Kassem, National Research Center, Cairo, Egypt. The project JEBEL (Jordanian and Egyptian Basement EvoLution) is funded for three years by the Swedish government through a grant to Prof. Vicky Pease of Stockholm University. It resulted from a Planning Workshop held in Egypt in February 2007, and attended by scientists from 8 different countries. The Swedish grant covers research and travel by Swedish, Egyptian, and Jordanian participants only, with U.S, Saudi, Norwegian, and German scientists to secure funding in their respective countries. This award will support the participation of four U.S. scientists in two field research and planning workshops for this new international research effort. The first workshop will be held in October 2008 in Egypt and the second to be held in Jordan in winter 2009-2010. Both workshops will discuss results of research to date and discuss future research priorities. Four days of field trips to key geologic localities in the southern Sinai and discussions are planned, in tandem with a day of research presentations and planning. Because US participation was key to the success of the 2007 workshop, and will be important for success of Project JEBEL, both the Swedes and the U.S. sides want to continue the US scientists? participation in this effort, which should lead to a complementary NSF effort. Intellectual merit: Project JEBEL focuses on four challenges: 1) understanding the Neoproterozoic evolution of Jordan, the Eastern Desert of Egypt (EDE), and in particular the central EDE, via geochronological, geochemical, stratigraphic, and structural studies; 2) facilitating geological correlations across the Red Sea, extrapolation of economic zones, and constraining palinspastic reconstructions of the Red Sea region; 3) correlating Neoproterozoic terranes and paleogeography within the Neoproterozoic orogen; and 4) contributing to understanding the development of the Neoproterozoic Earth environment. The results will be useful for estimating total offsets across the Red Sea from geologic markers. The northern part of the Arabian-Nubian Shield is one of the least studied parts of the major Pan-African Orogen that extends the full length of the African continent, and these workshops will focus international attention on the area. The two U.S. senior scientists, Dr. Stern and Dr. Peter Johnson (of JV Associates Ltd.) will have major inputs because of their extensive experiences in the region. Broader impacts: The involvement of both a current (Kamal Ali) and a former (Dr Mohamed Abdelsalam) PhD students of Dr. Stern will be of considerable benefit, and meets the goal of supporting early-career researchers. The involvement of the US team will potentially lead to new partnerships in research effort involving US scientists in a developing EU-Egypt-Jordan initiative, potentially providing important information on the geology of this region. The results from the workshops and research papers are expected to be widely disseminated, as Dr Stern has set-up a website for this project: http://www.utdallas.edu/~rjstern/egypt/. The observations made in the workshops will be used in this wider venue for virtual field guides and giving other investigators access to the observations. This project is being supported by the Office of International Science and Engineering and the Division of Earth Sciences.
