Locating intrinsic mineralization units in Mohsen Ebne Ali of Borujerd area by means of Remote Sensing data

Mohsen Ebneh Ali area is located south-east of Borujerd and in the north-west of Sanandaj- irjan zone. The main lithology of this area include Mesozoic volcano-sedimentary rocks which were metamorphosed in green schist facies. The study area with the variety of intrinsic geological units, introduce a high potential area for mineral exploration. In this respect, satellite images could give a good help to locate these units in a wide range views. In this research, Landsat ETM data were used to study petrology, hydrothermal alteration and tectonic structures. Different approaches were used such as band ratioing, principle component (PCA) and digital filtering. The structures were identified using remote sensing, methods and techniques provides the capability of creating a new lineament map of the study area. Based on this study, it is suggested that three areas are favorable for further exploration. To introduce intrinsic mineralization units, the highest probability of mineralization is considered. There are a close correlation between lineament structures and alteration zones in the area. Based on these studies, one group of alterations is detected to NW-SE faults in carbonate and metavolcanic rocks and others are detected to N-S faults and intersection of faults in areas with plutonic rocks.
