9627806 Barazangi The collision between Africa and Europe in the Western Mediterranean region resulted in a complex plate boundary with a broad zone of deformation. Mesozoic rift structures have been reactivated by the current tectonism, which itself occupies the foreland position of the collisional zone extending from Morocco to Tunisia. There are several examples of such intraplate mountain ranges but this one is tectonically active, and thus offers an opportunity to investigate active deformation mechanisms in this environment. The work involves kinematic analysis of microtectonic data and earthquake focal mechanisms. This project is a joint research effort with Moroccan institutions, principally the Geological survey of Morocco. Results are expected to be applicable to similar tectonics problems elsewhere.

9627806巴拉桑吉非洲和欧洲在西地中海地区的碰撞造成了复杂的板块边界和宽广的形变区。中生代裂谷构造被现今的构造作用重新激活，它本身占据了从摩洛哥延伸到突尼斯的碰撞带的前陆位置。有几个这样的板内山脉的例子，但这一个是构造活跃的，因此为研究这种环境中的活跃变形机制提供了机会。这项工作涉及微构造数据的运动学分析和地震震源机制。该项目是与摩洛哥机构，主要是摩洛哥地质调查局的联合研究工作。预计这一结果也适用于其他地方的类似构造问题。
