Abstract
Synergistic display of data recorded by different remote sensing has proved
extremely valuable for the extraction of geological features such as lineaments .
Accordingly , two satellite images were used for lineaments analyses which are
considered as indicators for rock fractures . Image resolution merge and
directional filtering methods were applied for lineaments extraction using GIS
techniques .Rose diagram and lineaments density analysis were used for the traced
lineaments . The output of these techniques are used to trace new lineaments as a
regional lineaments map . a synergistic display of these regional lineaments with
geophysical images allows the major lithological and structural boundaries to be
mapped . Evaluation of lineaments map and its rose diagram analyses shows that
the dominant lineament trend is mainly NW-SE and NE-SW. It is concluded that
these lineaments indicate the fault zones within the area. Besides, a considerable
conformity has been noticed between the location and dimension of such
lineaments with subsurface anomalies appeared in geophysical images
