Abstract

The MASJEDDAGHI area with 8.5 km2 extent is located in 35 km for east of jolfa. The geological exploration started in this area in 2003 and soil sample method was chosen due to the geological situation topography and weathering , The sampling network was 100m*100m and 100m*200m and all samples were analyzed for 13 elements .including Au, Cr, Co, Ba, Cu, Pb, Zn, Ag, Be, Mo, Sn, Mn. The geological studies shows that the oldest rock unit outcropped is Eocene flysh widely distributed in southern and north eastern part of the area .Another outcrops are mainly volcanic ,subvolcanic complex of andesite and trachyandesite, quartz monzonite and agglomerate (oligomiocene). In this area brecciated veins of barite – silicious and Cu, Pb, Zn sulfids and various pyrite type of mineralization have been identified. DATA PROCESSING have been carried out for analytical results(comparing main and duplicated samples data),and indicate normal distribution for Ni, Be ,Mn log distribution for other elements. That these two analysis methods, factor analysis and correlation matrix analysis (using standardizing the datas (x- x`/s)) have been consictent. Regarding The composite haloes, the result of studies indicate Au ,Ag, Be anomalies in eastern part of the area and Cu, Mo anomalies in western part of ARPACHAI valley. Considering the lithology and its relation to geochemical anomalies of the area, probable presence of porphyric Cu mineralization in eastern part and epithermal high sulfide Au mineralization in quartz-barite veins are identify.
