ABSTRACT:
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.
