Abstract :

The study area is located at 45 km southwest of Khaf and west of Zuzan village. Main rocks units are composed of plutonic and sub volcanic intrusive bodies as Diorite, Monzonite, Granodiorite and Granite. There is some slate in eastern part of the study area which are, according to field evidences older than intrusive bodies of the area. They are also affected by these intrusive bodies and are not in horizontal form any more. In this study area vast alteration zones are situated. Alterational zoning in the study area includes propylitic, Argillic, quartzsericite- pyrite (QSP), skarnification alteration and combination of them. There has not been any significant mineralization in the study area and there are just pyrite forms and iron oxide in QSP zone. There are also two Epidot skarn units in the middle of that part with an area of 1000 m2 which has 5.2 % Fe. Geochemical studies in the area are conducted in two fields of stream sediment and lithogeochemistry. Geochemical analysis results were obtained by 36-element method for chip composite samples and 41-element method for stream sediment samples in Acmelabs of Canada. The results of these analysis showed the anomaly of Pb and Zn in both stream sediments and chip composites in the southern parts of the study area. Maximum amount of Pb is approximately 489 ppm which is in concordance with QSP alteration zone in the eastern parts of the study area and the maximum amount of Zn is approximately 796 ppm which is in concordance with skarnification zone in the middle of the area. The Cu amount is in
normal level and its maximum amount is not higher than 35 ppm.
