The Kirazlı mineral district is located at the center of Biga peninsula metallogenic province, in a geological setting characterized by an extensional tectonic environment. hosts high-sulfidation (HS) ore body with total reserve 33.86 Mt @ 0.69 g/t Au and 9.42 Ag within large-scale hydrothermal alteration. Although ideal magmatic-hydrothermal models present spatial temporal association HS-epith...

1.0 Introduction The 0.4 to 2.5 μm spectral range provides abundant information about many important Earth-surface minerals (Clark et al., 1990). In particular, the 2.0 to 2.5 μm spectral range covers spectral features of hydroxyl-bearing minerals, sulfates, and carbonates common to many geologic units and hydrothermal alteration assemblages. Imaging Spectrometers, or “Hyperspectral” sensors pr...

introduction in remote sensing studies, especially those in which multi-spectral image data are used, (i.e., landsat-7 enhanced thematic mapper), various statistical methods are often applied for image enhancement and feature extraction (reddy, 2008). principal component analysis is a multivariate statistical technique which is frequently used in multidimensional data analysis. this method atte...

In this work, we focus on investigating the Quickbird and Landsat-8 datasets for mapping hydrothermal and gossans alterations in reconnaissance porphyry copper mineralization in the Babbiduyeh area. This area is situated in the Central Iranian Volcano-sedimentary Complex, where large copper deposits like Sarcheshmeh as well as numerous occurrences of copper exist. The alteration zones are discr...

The method of weights of evidence is one of the most important data driven methods for mineral potential mapping in GIS. In this method, considering the characteristics of known mineralized locations, we can prospect new mineralized areas. In this research work, the method of weights of evidence has been used for hydrothermal gold potential mapping in Torbat-e-Heydarieh area, east of Iran. As a...
