The Iraqi Western and Southern deserts are part of the Stable Shelf (Inner Platform) that belongs to Arabian Plate. Therefore, both lack tectonic forms like folds faults; however, very rarely faults regional lineaments can be seen in deserts. Although tectonically stable, tens Neotectonic indications everywhere Among those are: Straight valleys, perpendicular valley bendings, sinkholes aligned ...

Geological and morphostructural lineaments are considered as the surface expression of geological structures linear features valleys, ridges river drainage systems. Lineaments extracted from satellite images have always been effective in understanding structural context a region. The observed on provide information tectonic stresses that affected an area give first impression probable existence...

Mariner 6 and 7 images were used to investigate the nature and importance of linear surface trends on Mars. Cross correlations of frequency-azimuth distributions of linear trends from different Mariner frames indicate that linearions not recognized as topographic features have a component of artifacts, probably introduced during digital reconstruction of the images. Consequently, topographic an...

The fracture deformations often result in linear morphological elements (lineaments, valleys) on the surface. In many cases, direction of lineaments and valleys can be well followed by strike geological structural elements. Therefore, conclusions drawn from these directions for regional tectonic processes. Our work aimed to analyse relationship between valley lineament network south-eastern par...

The earth’s surface linear features, expressing geological lineaments, play a key role in identifying hydrothermal alteration and mineralization zones, as well understanding tectonic settings of region. objective this investigation is to utilize method for extracting lineaments automatically, which will be integrated applied identify geological-based by making use remote sensing data. study fur...

The main objective of this work is to design an automatic image processing tool for lineament mapping from LANDSAT-TM satellite data. In doing so, three procedures are involved: (i) image enhancement using histogram equalization technique; (ii) automatic lineament detection using Canny algorithm; and (iii) three-dimensional (3D) lineament visualization using SRTM data. The study shows that Cann...

Bends in volcanic hotspot lineaments, best represented by the large elbow in the Hawaiian-Emperor chain, were thought to directly record changes in plate motion. Several lines of geophysical inquiry now suggest that a change in the locus of upwelling in the mantle induced by mantle dynamics causes bends in hotspot tracks. Inverse modeling suggests that although deep flow near the core-mantle bo...

Introduction: The mapping of lineaments from digital remote sensing data is one of the techniques used in the structural and tectonic characterization of a planet. Lineament mapping on Mars is traditionally made using digital imagery [1,2]. MOLA altimetry data was also used to the visual interpretation and extraction of tectonic features from Mars surface [3]. All these works rely on traditiona...
