Abstract

Mohsen Ebneh Ali area is located southeast of Borujerd and in the northwest of Sanandaj-Sirjan zone. Main lithology of this area includes Mesozoic volcanosedimentary rocks which were metamorphosed in greenschist facies. The major types of Alteration include propylitization, silicification, carbonatization, hematitization and sercitization. Among those, propylitization are pervasive whereas, silicification and carbonatization are usually limited to the Mineralization zone. There are close correlations between lineament structures and Alteration zones in the area (Base on analysis Landsat ETM+ data). Lithogeochemistry is being routinely applied to gold exploration. Multi-element results undergo one stages of assessment: utilization of minor and trace elements let to identification of anomalous spots for determination of blind gold deposits in the study area. According to the present study, gold-anomalous zone is in the centeral part of map and perpendicular to metavolcanic rocks. Dominant host rocks of the anomaly are intermediate and mafic metavolcanics. Data accomplished enrichment of Ag, As, Sb, Zn, Pb, and Cu in Au anomaly. Calculated correlation coefficient in correlation matrix of elements showed a maximum gold positive correlation with As(+0. 81), Ag(+0. 73), Cu(+0. 68), Pb(+0. 64), Zn(+0. 63). Mineralization is considered a vein type and anomaly is hosted by metavolcanics which are mainly associated with silicic and iron oxide altration. The results of analysis show that gold content ranges from 0. 07 to 0. 5 ppm in quartz-carbonate veins and 1. 74 to 9. 8 ppm in quartz-Fe-oxide veins. The identified minerals in mineralographic studies are pyrite, chalcopyrite, bornite, covolite, malachite, hematite and goethite. Based on Alteration, host rock, geometry of Mineralization and mineralogy in the study area, gold Mineralization is related to lineament structures and faults.
