US-Turkey Workshop: The Tectonics of Eastern Turkey and Northern Arabian Plate, Istanbul, Turkey, May 2002

[01:14478 . barazangi]该奖项支持一个关于土耳其东部构造的联合研讨会和合作研究项目。讲习班将于2002年5月在土耳其伊斯坦布尔举行。联合组织者是纽约伊萨卡康奈尔大学地质科学系Muawia Barazangi博士和伊斯坦布尔Bogazici大学Kandilli天文台和地震研究所（KOERI）地球物理学教授Niyazi Turkelli博士。研讨会将重点讨论东安纳托利亚高原、Bitlis缝合带和东安纳托利亚断裂带的演化和起源。来自康奈尔大学和KOERI的科学家最近在土耳其东部部署了一个由美国国家科学基金会资助的临时帕斯卡尔阵列。该阵列旨在提高对Bitlis/Zagros逆冲带以及沿EAFZ和North Anatolian断裂带（NAFZ）的大陆逸出性质的认识，并在这两个截然不同的构造环境中成像上地幔和地壳结构。为了解释这些地震图像，有必要结合该地区的地球化学、地貌和地质观测。预计将有10名美国科学家和至少6名土耳其科学家参加。KOERI地震学家将多次前往康奈尔进行密切合作，分析最近从土耳其东部宽带阵列收集的数据。范围：该奖项将鼓励美国和土耳其科学家根据已收集的数据就几个重要的地质问题进行讨论。这些问题包括：阿拉伯板块是俯冲、分层还是两者都没有？安纳托利亚高原是动力支撑还是均衡支撑？土耳其东部目前的地震危险是什么？将邀请土耳其政府有关官员参加关于评价土耳其东部地震危险的结果所涉问题的特别会议。本项目的资金由国际项目司和地球科学司提供。

The co-organizers are Dr. Muawia Barazangi, Department of Geological Sciences, Cornell University, Ithaca, New York and Dr. Niyazi Turkelli, Professor of Geophysics at the Kandilli Observatory and Earthquake Research Institute (KOERI), Bogazici University, Istanbul. The workshop will focus on the evolution and origin of the Eastern Anatolian Plateau, Bitlis suture, and East Anatolian Fault Zone (EAFZ). Scientists from Cornell and the KOERI have recently deployed a temporary NSF-funded PASSCAL array in eastern Turkey. The array is designed to improve understanding of the Bitlis/Zagros thrust zones as well as the nature of continental escape along the EAFZ and North Anatolian Fault Zone (NAFZ), imaging upper mantle and crustal structure in these two fairly different tectonic environments. In order to interpret these seismic images, it is necessary to incorporate geochemical, geomorphic, and geologic observations from the region. Ten US scientists and at least six Turkish scientists are expected to participate. KOERI seismologists will make several trips to Cornell for close collaboration on the analysis of data collected from a recent broadband array in eastern Turkey. Scope: This award will encourage discussion among US and Turkish scientists on several important geological questions in light of data already collected. These questions include: Is the Arabian plate being subducted, delaminated, or neither? Is the Anatolian plateau supported dynamically or isostatically? What are the current earthquake hazards in eastern Turkey? Appropriate Turkish government officials will be invited to a special session on the implications of the results concerning the evaluation of earthquake hazard in eastern Turkey. Funding for this project is provided by the Division of International Programs and the Division of Earth Sciences.
