Title

APPLICATION OF DIFFERENT IMAGE PROCESSING TECHNIQUES ON ETM+ IMAGES FOR EXPLORATION OF PORPHYRY AND VEIN TYPE COPPER MINERALIZATIONS IN KUH-E-MAMZAR AND KUH-E-PANJ AREAS, KERMAN PROVINCE

Abstract

 The study area is situated in the southern part of the Central Iranian Volcano-Sedimentary belt. The Eocene volcano-sedimentary rocks are the main geological features in the area. These rocks are intruded by the Oligo-Miocene intrusive bodies where they caused an intensive alteration and formation of copper mineralization. Different IMAGE PROCESSING techniques such as band ratios, Costa technique, supervised FUZZY CLASSIFICATION, and lineament factor analysis are used for identification of the alteration zones associated with copper mineralization. The supervised FUZZY CLASSIFICATION of the images obtained through Costa technique was found to be the best IMAGE PROCESSING technique for delineation of the hydrothermally altered rocks associated with porphyry copper deposits. Analysis of the lineaments interpreted out of ETM+ (band 8) data is recognized as another method for locating porphyry and vein type copper mineralizations. There is a close correlation between photo lineament factor values and the known copper mineralization in the area. After analyzing and interpreting the processed images, a few selected sites were sampled. The thin sections and XRD data from the samples showed that ETM+ data was capable of mapping hydrothermal alteration.
