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.

对保加利亚中部和南部的活动和年轻变形的研究是特别有趣的，因为这种变形代表了爱琴海伸展域的最北端，因此代表了一个活跃的弧后型伸展，毗邻沿希腊俯冲和沿希腊俯冲边界的同时期俯冲和收敛带。研究表明，伸展是由俯冲板块的运动控制的，但这种系统的动力学和详细的运动学过程仍然知之甚少。该项目将与保加利亚科学院合作，详细研究沿希腊俯冲系统向北终止的活动俯冲与弧后区域向北终止的同时期伸展之间的关系，并最终深入了解驱动这些系统的动态过程。
