The current
study exposes the results of aeromagnetic data interpretation and a combined
analysis of 1-A sentinel radar image that cover the study area of Beni Mellal
Atlas in order to describe the structural geometry and to understand its
tectonic evolution.The map of the reduced to pole of residual magnetic field
highlights various magnetic anomalies with high amplitudes that correspond to
Jurassic-Cretaceous basaltic formations outcropping synclinal basins of Beni
Mellal Atlas. The interpretation of magnetic data using tilt derivative (TDR),
horizontal gradient technique coupled to upward continuation and Euler
Deconvolution allows us to distinguish the fractures network that is affecting
the study area. In order to complete this analysis, the Sentinel-A radar image
is processed and filtered using SNAP ESA Sentinel-1 toolbox software to extract
lineaments. The final structural map reveals four faults groups oriented
respectively NE-SW, ENE-WSW to E-W, N-S and NW-SE Their depths estimated by the
application of Euler deconvolution exceed 1500 m.Thoses faults have played a
major role in structural evolution of Beni Mellal Atlas.
We would like to thank the Applied Geology Division of the Ministry of Energy, Mines and Sustainable Development-Rabat, for providing the aeromagnetic data used in this study
