“…Finally, the extracted objects underwent post-processing for validation as well as to elucidate their geological and tectonic implications. ASTER, a collection of multispectral imageries, was launched aboard NASAs Terra platform within the Earth Observing System (EOS) in December 1999 [3,50,51]. The detailed specifics of the ASTER data are elucidated in (Table 1).…”

“…According to [7,50], tertiary tectonics in central Afghanistan appear to have been dominated by strike-slip faulting. This is evident in the vertical slices of sediment of various ages along a number of major faults, whose strikes vary from northeast close to the Chaman fault to east-west close to the Herat fault (Figure 2).…”

Ophiolites are remnants of oceanic crust that have been thrust onto continental crust due to tectonic processes. They are composed of mostly mafic and ultramafic rocks, which are genetically associated with gold, silver, platinum group element (PGE), chrome, manganese, titanium, cobalt, copper, and nickel deposits. The main objective of this research was to identify the spatial distribution of Mesozoic ophiolitic complexes within the Central Afghan Block in Middle Afghanistan using optical remote sensing data and spectral analyses. Distinct algorithms, such as false color composite (FCC), proposed band ratios (PBR), principal component analysis (PCA), and spectral angle mapper (SAM), were used to map the targeted ophiolitic complexes. New band ratios were proposed in this study based on the spectral properties of mafic-ultramafic minerals and rocks, which showed high efficiency. Based on the results, four different ophiolitic complexes were delineated within this study area. These complexes are consistent with previous studies. The accuracy assessment of this study showed an overall accuracy of 72.2%. The findings of this study can significantly contribute to further studies on the emplacement mechanism and paleo-Tethys history of Middle Afghanistan. Also, the spatial distribution of the ophiolitic complexes identified in this study can be used to constrain models of the tectonic evolution of the Central Afghan Block. Additionally, the identification of new band ratios for mapping ophiolitic complexes can be used in future studies of other ophiolite-bearing regions.

“…Geological lineaments, which include fault systems, fractures, and linear structures, are important parts of the Earth's surface and play an essential role in geological studies, particularly in geological processes, tectonic history, and the potential for natural resources [Masoud and Koike, 2006;Adiri et al, 2017;Doski, 2019;Ahmadi et al, 2023]. These lineaments provide a rare window into the inner workings of the Earth and important hints about the forces that have produced and are still shaping our globe.…”

The South Rifain ridges are an example of tectonic-sedimentation interaction in the Mio-Plio-Quaternary foreland basins at the front of the Rif chain. is an elongated mountain zone-oriented E-W and N-S, forming the most frontal part of the Rif belt. The morphotectonic study carried out in this area is based on Landsat-8 OLI image processing techniques to determine the contribution of these images to structural mapping. The results obtained reveal a predominant E-W orientation, which is widely present throughout the study area. This is followed by a second N-S direction, a third NW-SE direction, and a fourth NE-SW direction. The NW-SE lineaments are also mapped in kilometres. Their equivalent on the ground shows a sinister movement but does not show a significant horizontal displacement of more than a few metres. Together with the NE-SW faults, these faults form a conjugate system of dextral and sinistral faults, compatible with a palaeostress field where the maximum shortening stress is submeridian.
