Active Strain in Bulgaria, its Evolution & Position within the Middle East-Balkan Zone of Intracontinental Deformation

9628225保加利亚中部和南部活动和年轻变形的Burchfiel研究特别令人感兴趣，因为该变形代表了爱琴海伸展区域的最北范围，因此代表了邻近同时代俯冲和会聚带的弧后类型伸展的活跃例子，并沿着希腊俯冲和沿希腊俯冲边界会聚。研究表明，伸展是由俯冲板块的运动控制的，但描述这种系统的动态和详细的运动学过程仍然知之甚少。该项目与保加利亚科学院合作，将详细研究沿希腊俯冲系统向北终止活动俯冲与弧后地区同时代伸展向北终止之间的详细运动学，并最终进一步深入了解驱动这些系统的动态过程。

9628225 Burchfiel Study of active and young deformation in central and southern Bulgaria is of particular interest in that this deformation represents the northernmost extent of the Aegean extensional domain and thus represents an active example of back arc type extension adjacent to a zone of coeval subduction and convergence along the Hellenic subduction and convergence along the Hellenic subduction boundary. Studies suggest that extensions is controlled by motion of the subducting plate, but the dynamic and detailed kinematic processes that characterize such systems remain poorly understood. This project, collaborative with the Bulgarian Academy of Sciences, will study the detailed kinematics of how northward termination of active subduction along the Hellenic subduction system is related to northward termination of coeval extension in the back-arc region and ultimately, to gain additional insight into the dynamic processes that drive these systems.
