New kinematic reconstructions of the Adriatic Plate as a key to understanding subduction processes in the Western MediterraneanKAPMED

我们的目标是生成新的西地中海地区的运动学重建，重点关注亚得里亚海微板块在阿尔卑斯山脉演化过程中的关键时间片的独立运动。这将包括通过结合阿尔卑斯山脉、亚平宁山脉和第纳里德斯山脉的地质和地球物理信息，重建亚得里亚海微板块的运动路径。然后，这些重建将被用于将俯冲带位置的变化映射到现有的地幔过渡带板块的层析成像图像上。这将使我们能够将板块运动模型中俯冲的岩石圈的数量和年龄与观测到的地幔中板块异常的面积范围进行比较。这个三维运动学模型对于理解在活动和复杂构造系统中驱动俯冲的力量是至关重要的。

We aim to generate new kinematic reconstructions of the Western Mediterranean region, focussing on the independent motion of the Adriatic microplate for key time slices in the evolution of the Alpine mountain chains. This will involve reconstructing the motion path of the Adriatic microplate by combining geological and geophysical information from the Alps, Apennines and Dinarides. These reconstructions will then be used to map changes in the location of subduction zones onto existing tomographic images of slabs in the mantle transitional zone. This will enable us to compare the amount and age of lithosphere subducted in the plate kinematic model with the observed areal extent of slab anomalies in the mantle. This 3D kinematic model will be of central importance to understand the forces driving subduction in mobile and complex tectonic systems.
