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
