“…These structural discontinuities are often associated with linear geomorphological features such as valleys, ridgelines and slope breaks that are clearly discernible on the Earth's surface (Jordan and Schott, 2004). Remotely sensed satellite images are widely used for fast identification, extraction, and mapping of these structural lineaments (e.g., Pike, 1991;Simpson and Anders, 1992;Jordan and Schott, 2004;Hung et al, 2005;Sarp, 2005;Saadi et al, 2011;Argyriou, 2012). The identification of lineaments would be extremely difficult if it is depended only on fieldwork.…”

“…The identification of lineaments would be extremely difficult if it is depended only on fieldwork. Lineament mapping and analysis is, however, a significant part of neotectonic and structural geology studies since they can provide essential clues about late Quaternary tectonic deformation and environmental hazards (Panizza and Castaldini, 1987;Shake and McHone, 1987;Gabrielsen et al, 2002;Ramli et al, 2010;Koike, 2011a, 2011b;Saadi et al, 2011;Ali, 2012).…”

This study investigates the dominant orientations of morphological features and the relationship between these trends and the spatial orientation of tectonic structures in SW Jordan. Landsat 8 and hill-shaded images, constructed from 30 m-resolution ASTER-GDEM data, were used for automatically extracting and mapping geological lineaments. The ASTER-GDEM was further utilized to automatically identify and extract drainage network. Morphological features were analyzed by means of azimuth frequency and length density distributions. Tectonic controls on the land surface were evaluated using longitudinal profiles of many westerly flowing streams. The profiles were taken directly across the northerly trending faults within a strong topographic transition between the low-gradient uplands and the deeply incised mountain front on the east side of the Dead Sea Fault Zone. Streams of the area are widely divergent, and show numerous anomalies along their profiles when they transect faults and lineaments. Five types of drainage patterns were identified: dendritic, parallel, rectangular, trellis, and modified dendritic/trellis. Interpretation and analysis of the lineaments indicate the presence of four main lineament populations that trend ~E-W, ~N-S, NE-SW, and NW-SE. Azimuthal distribution analysis of both the measured structures and drainage channels shows similar trends, except for very few differences in the prevailing directions. The similarity in orientation of lineaments, drainage system, and subsurface structural trends highlights the degree of control exerted by underlying structure on the surface geomorphological features. Faults and lineaments serve as a preferential conduit for surface running waters. The extracted lineaments were divided into five populations based on the main age of host rocks outcropping in the study area to obtain information about the temporal evolution of the lineament trends through geologic time. A general consistency in lineament trends over the different lithological units was observed, most probably because repeated reactivation of tectonism along preexisting deep structural discontinuities which are apparently crustal weakness zones. The reactivation along such inherited discontinuities under the present-day stress field is the most probable explanation of the complicated pattern and style of present-day landscape features in SW Jordan.

This study used an integrated approach to investigate geological structure and tectonic evolution in Central Afghanistan. Several image processing techniques have been separately and simultaneously applied to data obtained from Landsat Enhanced Thematic Mapper Plus (ETM+) and Digital Elevation Models (DEM) to constrain the geological structure of the study area. Satellite images were combined with Gravity data to better understand 3D geology in the area. Analysis and interpretation of the extracted lineaments indicate that the Central Afghanistan area is controlled by two main fault systems, trending NE and EW. The two trends represent the remnants of reactivated structures that formed under the stress regimes generated during the tectonic evolution of Central Afghanistan. Gravity data indicate a NE trending basin. A two-dimensional (2D) schematic model shows that the basin deepens in the central area and gradually shallows towards the edges. The integration of the results gave insight into the tectonic evolution of the Central Afghanistan area and the adjacent areas.

“…Broad lithological information is deduced from a variety of indicators observed in remotely sensed imagery, including landforms, structural features, soils, vegetation types and drainage patterns (Agar and Coulter, 2007;Gad and Kusky, 2006;2007;Hewson et al, 2005;Rajesh, 2004). Many authors have studied the strong correlation between lineament interpretation and analysis of remotely sensed imagery, leading to discoveries of major mineral deposits of great economic value (Fernades da Silva et al, 2005;Hashim et al, 2013;Meijerink, 1996;Rajesh, 2004;Rinaldi, 2007;Saadi et al, 2011).…”
