Les chevauchements frontaux du Haut Atlas central marocain : styles structuraux et taux de raccourcissement différentiel entre les versants nord et sud

The borders of the Central High Atlas chain showed different structural styles, as revealed by the interpretation of recently acquired surface geology and sub-surface data. Structures, characterizing thick and thin skin tectonics, are variable from west to east and from south to north, while both shortening and deformation intensities decrease in the same directions. These differences are essentially related to the attitude of inherited Hercynian fault pattern and to the Mesozoic development of the Central High Atlas.
