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...

INTRODUCTION A high-resolution aeromagnetic survey collected over the North Slope of Alaska by World Geoscience was acquired in response to a need for highly detailed data in an areawhere traditional geophysical techniques are expensive and prohibitive (McConnell, 1995) (Figure 1). These data were recently released to the University of Texas’ Institute for Geophysics and provide a unique opport...

Aeromagnetic exploration is a magnetic method that detects changes of the earth’s field by loading magnetometer on an aircraft. With miniaturization magnetometers and development unmanned aerial vehicles (UAV) technology, UAV aeromagnetic surveying plays increasingly important role in mineral other fields due to its advantages low cost safety. However, process measurement data, ferromagnetic ma...

Structural analysis of remotely sensed data provides a method of assessing the structural significance of regional metallogenesis in the Dehaj area as the northwestern part of the Kerman porphyry Cu belt. This belt is consisted of dominant Eocene volcanics and the Dehaj type subvolcanic intrusives. In the study area, geologically, Cu-mineralization is hosted by the Kuh-e-Panj type subvolcanic i...

Global Positioning System vectors and surface tilt rates are inverted simultaneously for the rotation of western Oregon and plate locking on the southern Cascadia subduction thrust fault. Plate locking appears to be largely offshore, consistent with earlier studies, and is sufficient to allow occasional great earthquakes inferred from geology. Clockwise rotation of most of Oregon about a nearby...

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...
