Abstract :

The Argash antimony ore deposite is located 45 Km south of Neyshabour. The ore deposite hosted by a sequence of intermediate to silicic volcanic rocks, granite and granodiorite. The mineralization occurs as open space filling, taking place as irreqular veins and veinlets. Field and microscopic evidences indicate four stages in paragentic sequence. Prophyllitic alteration, argillic alteration and silicification are the main hydrothermal alteration types. The evaluation of the geochemical data set was processed by using different multivariate statistical methods, which led to both geochemical and practical results. These results can be used in exploration of mineralization veins, because areas of high grade can be predicated. Combination of the geological and mineralogical data and the geochemical behavior of the elements indicate the same distribution pattern of Sb, As and Ag which have most concentration in the silicified zones.
