Date of Defense 2007-07-24 Availability unrestricted Abstract This study shows that remote sensing and GIS are powerful tools in identifying geologically induced lineaments from digitally enhanced ETM+ satellite imageries and the digital elevation model (DEM) in remote areas such as the Makran accretionary prism, southeast Iran. The presence of the conjugate shear fractures in the eastern part, along with the extensional, and the presence of reidal sets associated with the subsidiary fractures of the Minab-Zendal fault system in the western part, suggests that the structural pattern changes from pure shear to simple shear from east to the west across the prism. Moreover, the gradual increase in the value of the angle between the two conjugate shear fractures, from south (coastal Makran) to north across the prism, and the presence of high-angle north-dipping reverse faults, with few south-dipping normal faults, suggest that deformation changes from brittle, in the south, to ductile in the northern part of the prism.Files
