Abstract : The Makkah-Jeddah region is located in the central-western part of the Arabian Shield and covered by well-exposed Precambrian layered and intrusive rocks as well as Tertiary sedimentary rocks and harrat. Good rock exposures, diversity of rock types, and distinctive tectonic trends made the study area an ideal example for the application of GIS and remote sensing techniques in geological and structural mapping in comprehensive, adequate and integrated manner. Automatic extraction of structural lineaments was performed using LINE module of PCI software package v. 9.1 through customization of sets parameter values. The optimal parameter values were applied on panchromatic band and extracted lineaments were edited and analyzed using ArcGIS software package v. 9.2. Image processing techniques which were applied on Landsat-7 ETM+ data include false color composite (FCC), decorrelation stretch, principal components analysis (PCA) and image ratioing. ERDAS IMAGINE software package v. 8.7 was used in image processing. The final geological and structural lineament maps were constructed under GIS system based on processed remote sensing images, previously published maps, field investigation, and GPS coordinates. The best FCC combination for drawing geological map is 7, 4 and 1 bands on RGB, and pan-sharpened with panchromatic band. The most informative combination of PCs is PC1, PC2 and PC3 on RGB. Moreover, the ratioing techniques showed good capability as tools for rock type discrimination. Analysis of structural lineaments revealed that the NE trend is dominant. Anomalous parameters of sructural lineaments density; lineament to cell intersections and Kim length are almost coincident to some extent, and anomalous parameters of structural lineaments intersections density; lineament to lineament intersections and Kim intersections are also matched. Integration of anomalous structural lineament maps, geological map and mineralization sites map indicated that diorite has the highest lineament parameters, and mineralization sites are controlled the most extensive fractures. Two promising areas were proposed for mineralization sites these are; Wadi Umm Hablayn area at the northwestern part of the study area and Jabal Ath Thurayya area at southeastern part of the study area. Results which have been achieved in the present study showed the effectiveness of GIS and remote sensing techniques as powerful tools in geological mapping and automatic extraction and analysis of structural lineaments. It is noteworthy to recommend that the extension of the study area, in which applications are carried out, must be taken into consideration in order to attain reasonable outcome.
