Seismotectonics and Lithospheric Structure of the Intracontinental Atlas Mountain Belts of Morocco: Continental Delamination

本研究旨在研究摩洛哥阿特拉斯山系的岩石圈结构和活动构造。康奈尔大学和摩洛哥的研究机构联合建立了一个现代化的遥测数字地震网，该网最近安装的数据将用于这项工作。阿特拉斯山带是一个具有丰富的活动褶皱和逆冲走滑断裂的活动压陷系统。它的演化和结构与大多数位于板块会聚边界的山带，如喜马拉雅山脉、扎格罗斯山脉、安第斯山脉和阿尔卑斯山脉，有着根本的不同。不同的岩石圈模型将通过地震和重力数据进行测试，以解释阿特拉斯山脉下明显的质量过剩。这项研究是国家减少地震危害计划的一个组成部分。

This research is to study the lithospheric structure and active tectonics of the Atlas mountain system in Morocco. Data produced by a recently installed modern, telemetered, digital seismic network in a joint effort by Cornell University and institutes in Morocco will be used in the effort. The Atlas mountain belt is an active transpressive system with abundant active folding and thrust and strike-slip faulting. Its evolution and structure is fundamentally different from that of most mountain belts located along convergent plate boundaries, such as the Himalayas, Zagros, Andes, and Alps. Different lithospheric models will be tested by seismic and gravity data to explain an apparent excess of mass beneath the Atlas mountains. This research is a component of the National Earthquake Hazard Reduction Program.
