RUI: Structure and Tectonics of an Inner-Tauride Ohiolite and Associated Shear Zone in Southern Turkey

东地中海蛇绿岩在Bitlis-Zagros缝合线以北形成不连续的海相断裂带，标志着阿尔卑斯-喜马拉雅造山带的先天碰撞带。然而，这次海洋闭合的古地理和时间是非常复杂和知之甚少的。该项目研究的Alihoca蛇绿岩位于南部相对未变形且地层完整的蛇绿岩（Troodos）和北部变形破碎杂岩之间的关键位置。它与非洲-阿拉伯亲缘的大陆碎片并列，并被岛弧岩侵入，因此可能保留了俯冲和碰撞带构造的证据。这项工作的主要内容是野外测绘、构造分析，其次是岩石学和地质年代学研究。研究结果将检验目前关于中生代地中海东部演化的模型。

The eastern Mediterranean ophiolites form discontinuous linear belts of oceanic fragments immediately north of the Bitlis-Zagros suture, which marks a congenital collision zone in the Alpine-Himalayan orogenic belt. The paleogeography and timing of this ocean closure however is very complex and poorly understood. This project will study the Alihoca ohiolite which occupies a key position between the relatively undeformed and stratigraphically complete ophiolites to the south (Troodos) and deformed and fragmented complexes to the north. It is juxtaposed against a continental fragment of Afro-Arabia affinity and intruded by island-arc rocks, thus potentially preserving evidence of subduction and collision zone tectonics. The main thrust of the work is field mapping, structural analysis followed by petrologic and geochronologic studies. Results will test current models for the evolution of the eastern Mediterranean during the Mesozoic.
