Integration of Aeromagnetic Data and Landsat Imagery for Structural Analysis Purposes: A Case Study in the Southern Part of Jordan

摘要

In this study, different digital format data sources including aeromagnetic and remotely sensed (Landsat ETM+) data were used for structural and tectonic interpretation of the southern part of Jordan. Aeromagnetic data were analyzed using advanced processing techniques (Spectral analysis, deconvolution). The aeromagnetic interpretation was carried out using the analytical signal, horizontal gradient, vertical gradient, Euler deconvolution. The results were improved by the study of enhanced Landsat ETM+ images and correlated with the extracted surface lineaments. Two main lineament sets are observed in the study area. The major lineaments strike NW-SE, NE-SW and the minor E-W. General coincidence of both landsat and aeromagnetic lineaments trends were observed in the study area, which reflecting the real continuous fractures in the depth. The 3D Euler solution of the study area shows that the depth of the magnetic source body ranges from hundreds of meters to more than 3000 m in the middle northern part of the study area. The combined interpretation of aeromagnetic data and Landsat ETM+, added several significant structural elements, that were previously unrecognized from the separate interpretations of aeromagnetic and remotely sensed data.
