Interpretation of potential gravity anomalies of Ouled Abdoun phosphate basin (Central Morocco)

The gravimetric maps are often used to delineate the geological bodies and structures. in the present paper,a reconnaissance work is presented to searching the sources nature of gravity anomalies of the ouled abdoun basin in moroccan meseta region. to achieve this goal,several filtering techniques are demonstrated on a bouguer gravity database. firstly,we separate the shallow sources gravity effects from regional effects,using regional-residual separation. secondly,two high-pass filtering are accomplished to enhance the anomaly wavelengths associated with the shallow sources. these processing techniques are the regional-residual separation,the total horizontal derivative and the laplacian operator. the qualitative interpretations of the findings reflect the occurrence of various types of geological structures in this region and the boundaries are widely enhanced more precisely using these methods. we note that ouled abdoun basin is a promising prospect in terms of sedimentary phosphate exploiting. © 2017,university of mohammed premier oujda morocco.
