Abstract

The region under investigation covers art area of approximately 3,500 square kilometers, located to the north of Tehran (the Capital of Iran), between the Karaj River to the west and the Damavand Volcano to the east. It is an area of high to moderate relief consisting of sedimentary rocks of Paleozoic and Mesozoic ages and tertiary rocks of volcanic origin.The study evaluates the utility of using Landsat MSS data in regional geologic analyses. Conventional techniques of image interpretation as well as digital enhancement and classification techniques were investigated. This analysis is important because the presence and orientation of the structural features can have great significance, and correlations may exist between them and zones of weakness characterized by seismic activity and mineral concentrations.The structural features (lineaments) detected on computer‐enhanced imagery of the study area exhibited definite trends providing a regional view of the geological “grain”; of the area. When alignments seen on Landsat imagery were plotted on a map, a correlation was found between lineaments detected on the enhanced scene and earthquake epicenters, as well as the mapped location of phosphate deposits of the study area. © 1989 Taylor & Francis Group, LLC.
