Glauconite is a greenish ferric-iron silicate mineral with micaceous structure, characteristically Dining formed in shallow marine environments.Glauconite has been used as a pigmentation agent for oil paint, contaminants remover in environmental studies and a source of potassium in plant fertilizers, and other industries.Koppeh-dagh basin is extended in Iran, Afghanistan and Turkmenistan countries and Glauconite units exist in this basin.In this research for enhancing and mapping glauconitic units in Koppeh-dagh structural zone in north 3 Ball Totes east of Iran, remote sensing techniques such as Spectral Angle Mapper classification (SAM), band ratio and band composition methods on SPOT, ASTER and Landsat data in 3 steps were applied.
