Tectonothermal Evolution of the Internal Alpine-Carpathian Orogen: Implications for Collisional Tectonics

最近对东阿尔卑斯和喀尔巴阡山脉的岩石学、年代学和构造研究表明，该地区在亚得里亚海微板块和覆盖的欧洲板块之间发生了单独的中生代碰撞事件。该地区碰撞事件的精确时间尚不清楚，该项目将提供系统的40Ar/39Ar矿物和整个岩石年龄，沿着阿尔卑斯内部和喀尔巴阡山脉的三条穿越。特别强调的是来自糜棱岩变形带的白云母的测年。与奥地利、匈牙利、罗马尼亚和斯洛伐克的科学家合作，将提供构造和地质框架。研究结果将对阿尔卑斯-喜马拉雅造山带这一重要板块演化过程中的个别碰撞和伸展事件的时间提供严格的约束，并将对该地区的构造重建产生影响。

9316042 Dallmeyer Recent petrological, geochronological and structural studies of the Eastern Alps and Carpathian Mts. suggest that a separate Mesozoic collisional event occurred in this region between the Adriatic microplate and the overridden European plate. The precise timing of collisional events in this area is unknown, and this project will provide systematic 40Ar/39Ar mineral and whole rock ages along three traverses across the Internal Alps and Carpathians. A special emphasis will be the dating of muscovite from mylonitic deformation zones. Collaboration with scientists in Austria, Hungaria, Romania and Slovakia will provide the structural and geological framework. The results will provide tight constraints on the timing of individual collisional and extensional events during the evolution of this important sector of the Alpine- Himalayan orogenic chain and will have implications for tectonic reconstructions of the region.
