INT 0002203FlowerThis U.S.-Eastern Europe workshop on "Mantle Dynamic Response to Africa-Eurasia Collision" features an active tectonic system encompassing the region of Pannonia, Carpathia, and Dinaride (PANCARDI). Many U.S. and European experts view this system, generated in response to the Mid-to Late-Tertiary Africa-European plate collision, and the PANCARDI region as a natural, transnational laboratory for examining the cause of widespread intro-continental magmatism. The U.S. workshop organizer, Martin F. J. Flower of the University of Illinois at Chicago, and his Romanian counterpart, Victor I. Mocanu of the University of Bucharest, intend to bring together an interdisciplinary group from the United States and Central and Eastern Europe to examine recent research findings that point to collision-induced mantle flow as a driver of lithosphere escape, volcanic arc rollback and basin opening. The workshop will take place north of Bucharest in Covasna, Romania, during June 17-21, 2000.After site visits and workshop discussions, participating junior and senior geologists, geophysicists and modelers from the U.S., Romania, Poland, Hungary, the Czech and Slovak Republics, Germany and Ukraine will formulate new cross-disciplinary research synergies and refine plans for follow-on cooperative research projects that incorporate seismic shear-wave splitting, geochemical-isotope studies and numerical modeling. Results should clarify next steps for understanding geodynamic evolution and collision-related asthenospheric responses as causes of basaltic volcanism. This workshop on mantel dynamics associated with continental plate collisions fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Eastern Europe to combine complementary talents and share research resources in areas of mutual interest and competence.

这个关于“地幔对非洲-欧亚大陆碰撞的动态响应”的美国-东欧研讨会，展示了一个活跃的构造系统，包括潘诺尼亚、喀尔巴西亚和迪纳里德（PANCARDI）地区。许多美国和欧洲的专家认为，这个系统是对中第三纪到晚第三纪非洲-欧洲板块碰撞的反应，PANCARDI地区是一个自然的、跨国的实验室，用于研究广泛的大陆内岩浆活动的原因。美国研讨会的组织者，芝加哥伊利诺伊大学的Martin F. J. Flower和他的罗马尼亚同行，布加勒斯特大学的Victor I. Mocanu，打算召集一个来自美国和中欧和东欧的跨学科小组来研究最近的研究结果，这些研究表明碰撞引起的地幔流是岩石圈逃逸、火山弧回退和盆地开放的驱动因素。讲习班将于2000年6月17日至21日在罗马尼亚布加勒斯特北部的科瓦斯纳举行。经过实地考察和研讨会讨论，来自美国、罗马尼亚、波兰、匈牙利、捷克和斯洛伐克共和国、德国和乌克兰的初级和高级地质学家、地球物理学家和建模师将制定新的跨学科研究协同效应，并完善后续合作研究项目的计划，包括地震剪切波分裂、地球化学同位素研究和数值模拟。研究结果应阐明下一步的工作，以了解地球动力学演化和碰撞相关的软流圈响应是玄武岩火山活动的原因。这次与大陆板块碰撞有关的地幔动力学研讨会实现了通过使美国和东欧的专家在共同感兴趣和能力的领域结合互补的人才和共享研究资源来推进科学知识的计划目标。
