“…For example, lineaments that are parallel to one another can indicate the presence of a major fault system, while intersecting lineaments can suggest a complex geological environment with multiple sets of faults. By analysing the orientation and characteristics of lineaments, researchers can gain insights into the tectonic history of the region and the underlying geological processes that have shaped it (Lyu et al, 2017;Seraj et al, 2020).…”

In this paper, we present a novel method for determining the depth of lineaments using satellite gravity data, which we test in the Sahel of Sfax area (eastern Tunisia). This region has a relatively flat topography with few significant discontinuities at the surface.As a first step, we used morphometric indices such as slope, aspect, and hydrographic network, calculated from SRTM-DEM, to generate separate lineament maps. We then combined these lineaments into a synthetic lineament map, which showed a high level of agreement with the Bouguer anomaly map derived from satellite gravity data and with previous studies that used geophysical data (seismic and gravity). We also validated the lineament map using field data.By fusing these lineaments with the 3D Euler solution map, we were able to deduce the depth classification of the lineaments. Our results demonstrate the effectiveness of our proposed method in estimating the depth of lineaments and its potential to provide valuable insights into the subsurface geology of an area. This method can be a useful tool for mineral exploration, hydrocarbon exploration, and geohazard assessments.

“…It contains a > 5 km thick of the Fars Group sediments (Figure S1; Gachsaran, Mishan, Aghajari, and Bakhtiyari formations) (Abdullahie Fard et al, 2011;Shamszadeh et al, 2022a). This region is co-located with 45 natural oil fields, equal to ~8% of Earth's total (Najafi et al, 2014;Seraj et al, 2020;Najafi and Lajmorak, 2020;Shamszadeh et al, 2022a) (Figure 1). It is formed from the west of the Kazerun fault zone to the Balarud fault zone in the northwest and in the footwall of the Mountain Front Flexure (MFF) (Berberian, 1995;Allen and Talebian, 2011;Shamszadeh et al, 2022a) .…”

“…In the Dezful Embayment, layer-parallel shortening resulting from the Zagros orogeny is accommodated by several symmetric and asymmetric mostly NW-SE trending anticlines and synclines (Figure 1) (e.g. Sherkati et al, 2006;Seraj et al, 2020).…”

On 2021 April 18, an Mw 5.9 earthquake struck the Genaveh region in the south Dezful embayment of the Zagros, Iran. Here, we investigate the active tectonics of the region, the geometry and slip distribution of the causative fault plane, and its aftershock behavior. We applied a combination of different geodetic and seismological methods (slip distribution inversion of the mainshock using Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR), relocation, and moment tensor inversion of aftershocks and background seismicity of the region). Co-seismic InSAR modeling shows that the slip is confined to the sedimentary cover at depths of 4-7 km with a maximum slip of 1 m and highlights the influence of lithology in the rupture propagation. Moment tensors and centroid depths of aftershocks down to Mw 4 show that the distributed aftershocks sequence is dominated by reverse faulting at centroid depths of 4-10 km. The causative fault is compatible and parallel to the trend of the Gulkhari anticline and the coseismic uplift of the Genaveh earthquake implies that the growth of this particular fold is linked to the fault(s). However, still, due to the absence of surface rupture, the clear relationship between buried faulting and surface folding remains unclear.
