Pre-Alpine Terranes of the Balkan Peninsula, Bulgaria: A Field, Geochronologic and Geothermobarometric Assessment of their Tectonic Significance

这个国际合作研究项目将汇集来自美国和保加利亚的研究人员。主要研究人员是密歇根大学的Samuel Mukasa博士和保加利亚科学院地质研究所的Ivan Haydoutov博士。他们建议对巴尔干地区出现阿尔卑斯山脉之前的历史进行时间限制。这是一项为期12个月的研究，旨在确定巴尔干半岛罗多比和斯雷内戈瑞地区蛇绿岩和变质岩的结晶、变质和冷却年龄，目的是重建该地区前阿尔卑斯山脉的演化，以及从阿尔卑斯山脉前的欧洲到土耳其以及更远的南部和东部地区的构造联系。巴尔干地区目前是我们重建特提斯洋南北边缘白垩纪前构造地体能力的一个主要漏洞，在奥地利/前南斯拉夫和土耳其之间的相关事件和地体方面存在主要的不确定性。这个项目是一个极好的机会，可以开始汇编数据，揭开巴尔干地区古老的构造历史，并将特提斯西部到东部的构造地形和变形事件联系起来。这个地球科学研究项目实现了将美国和中欧/东欧的顶尖专家聚集在一起的计划目标，在平等、互惠和互利的基础上，在共同感兴趣和能力强的领域结合互补的努力和能力。

This international collaborative research project will bring together researchers from the United States and Bulgaria. The principal investigators are Dr. Samuel Mukasa from the University of Michigan and Dr. Ivan Haydoutov from the Geological Institute of the Bulgarian Academy of Sciences. They propose to establish timing constraints on pre-Alpine history of the Balkans.This is a 12 month study to date the crystalization, metamorphic and cooling ages of ophiolitic and metamorphic rocks from the Rhodope and Srednegorie regions of the Balkan Peninsula, with the goal of reconstructing the pre-Alpine evolution of this region and the tectonic ties from pre-Alpine Europe through to Turkey and regions farther south and east. The Balkan region currently represents a major hole in our ability to reconstruct pre-late Cretaceous tectonic terranes along the northern and southern margins of the Tethys ocean, with major uncertainties about correlating events and terranes between Austria/former Yugoslavia and Turkey. This project is an excellent opportunity to begin to compile the data that will be needed to unravel the older tectonic history of the Balkan region and to connect the tectonic terranes and deformational events from western to eastern Tethys.This project in earth sciences research fulfills the program objectives of bringing together leading experts in the U.S. and Central/Eastern Europe to combine complementary efforts and capabilities in areas of strong mutual interest and competence on the basis of equality, reciprocity, and mutuality of benefit.
