Abstract: Lineaments are mapable linear surface features, which presumably reflect subsurface phenomena. The study demonstrates the use of ALOS imagery for lineament mapping for geological application. The image was enhanced and used for lineaments extraction through on-screen digitising. The extracted lineaments were evaluated against the published geological map for the study area using GIS o...

Utilization of the digital Landsat TM bands for automatic lineaments extraction and selection of the optimum bands are the main objects of this article. The classical method for lineament extraction was manually performed through aerial photographs and satellite imagery. Nowadays several commercial softwares are developed to deal with the automatic linear features extraction using the optical a...

geological studies are basic formof operations for the exploration and development of oil and gas fields.preparation of topographical and geological maps and drawingcross section from thesemaps formspart of these operations. existing lineaments in the study area are important, and should be considered in drawing the geological sections. the evaluation of wells stability is one of the important ...

The studied region in this research (Alborz province) is structurally located in Alborz poly_orogenic system of northern Iran. The purpose of this research is combining the remote sensing and geology sciences to show fault lineaments by analyzing satellite data in a vast region and also comparison between lineaments layer and recognized faults in geology maps. Firstly, two scenes of Landsat ETM...

Earth consists of hard rock layers where water is restricted to secondary permeability, and thus to fractures and the weather zones. Structural geology studies, geologic lineaments and their pattern information are essential for better planning and execution of projects to avoid any natural hazards. Satellite images, aerial photographs and digital elevation models will give lineament informatio...

An integrated approach with remote sensing, GIS and traditional fieldwork techniques was adopted to assess the groundwater potential in the central highlands of Eritrea. Digitally enhanced color composites and panchromatic images of Landsat TM and Spot were interpreted and thematic maps on lithology and lineaments prepared. Structural features were measured in the field and orientations compare...

[1] Lineaments in the gravity field and associated chains of volcanic ridges are widespread on the Pacific plate but are not yet explained by plate tectonics. Recent studies have proposed that they are warps and cracks in the plate caused by uneven thermal contraction of the cooling lithosphere. We show that the large thermoelastic stress produced by top-down cooling is optimally released by li...

A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will comprise a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features. Fracture zones, shear zones and igneous intrusions such as dykes can also give rise to lineaments. Lineamen...

Remote sensing, one of the most important reconnaissance and feature identifying tools generally applied for surface and groundwater investigation, was used for water resources mapping for the lower Son Valley in this study. The mapping was done with the help of Indian Remote Sensing (IRS) satellite imagery IRS-LISS1-B1 for January 29, 1991 obtained during the day transit time. The area under s...

Introduction: The Near-Earth Asteroid Rendezvous NEAR-Shoemaker spacecraft orbited the asteroid 433Eros for a year from 2000-2001. The NEAR Multi-Spectral Imager (MSI) collected tens of thousands of high resolution images and as a result Eros is the most comprehensively studied asteroid in the solar system. Previous mapping of lineaments on Eros has supported the suggestion of planes throughout...
