Remote sensing data is very important for the study of structural geology and extraction of lineament, it gives a glimpse of tectonic events. The main purpose of this study is to plan a to the extraction method, and lineament mapping from satellite images of Landsat (ETM+) in the study area. The area of this study is one of the important places in Libya, which contains the iron Ore deposits, therefore, the study of geological structures (lineaments) is one of the most important factors, which gives indications about the locations of ore deposits; lineament extraction and analysis represent one of the routines in mapping large areas using remotely-sensed data, most of which is the satellite images. Lineament analysis of a selected area is carried out with the aid of a Landsat ETM+ satellite image and by the application of various image processing techniques. Lineaments were visually interpreted from the enhanced images where lineaments were well over 2 km long and manually traced. The width of the lineaments in the interpreted images were various but not considered for lineament analysis. In the study, a total area of 1105 lineaments were recognized and analyzed. |
