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

Shallow crust structure of the Büyük Menderes graben through an analysis of gravity data

“…In general, faults are expected to be situated at or near the steepest gradient of the anomaly. As pointed out by Gout et al (2010), this characteristic is particularly helpful in areas where the fault zone is concealed by younger sedimentary deposits. The maximum value of the HGM and analytic signal indicate the source edge, and maximum values indicate the boundary faults of the graben mainly on the E-W and the SW-NE trends (see Figures 6a and 6b).…”

“…Gravity anomalies have been used as a powerful tool for geological mapping (Nabighian et al, 2005;Gout et al, 2010;Uieda and Barbosa, 2012;Guo et al, 2014;Wang et al, 2014;Chen et al, 2015;Ali et al, 2017;Wang, 2017). To define the linear features and the crustal structure of the basin, the Bouguer gravity anomaly data provided by a joint study of the General Directorate of Mineral Research and Exploration of Turkey (MTA) and the Turkish Petroleum Corporation (TPAO) were used.…”

3D Modelling and Basement Tectonics of the Niger Delta Basin from Aeromagnetic Data

“…The N-S and E-W bounded fault blocks are secondary faults which must have influenced stratigraphy and major tectonic elements or as shears which controlled local features. [39] and [40] mapped family of faults with similar trends that control depositional history of the sedimentary basin in north-eastern Morocco and Potiguar rift basin in northeast Brazil respectively. The N-S trending structures were probably induced by a combination of differential subsidence across a fault zone and by local uplift due to wrench movements.…”
