Main structural lineaments of north-eastern Morocco derived from gravity and aeromagnetic data

Many years ago, geophysical surveys (gravity and aeromagnetic) were initiated for economic investigation and recently the analysis of gravity and magnetic anomalies are used as a powerful tool for the geological mapping. The present study is based on various filtered maps of gravity and aeromagnetic anomalies of north-eastern Morocco (NEM) in order to highlight its main structural features. Filtering techniques such as horizontal gradient, upward continuation and Euler deconvolution were used to map structural lineaments in NEM. The obtained structural map is consistent with many faults already recognized or supposed by traditional structural studies, and highlights new major accidents by specifying their layout and dips.
