Abstarct: The Garmabe Paein Cu-Ag and Asbkeshan kaoline deposits are located in 290km southeast of Shahrood, within Upper Cretaceous volcano-sedimentary sequence, in the Sabzevar subzone of the Central Iran zone. The major host rocks of the Garmabe Paein deposit include trachyandesite, andesite basalt, and minor tuffaceous siltstone. Host rocks of the Asbkeshan deposit is andesite and shale. Sulfide mineralization within the host sequence occurred as sheet-like and tabular shape within the two horizons, first horizon involves the Garmabe Paein deposit, and is more copper-rich, and the second horizon involves the Asbkeshan deposit. baxsed on nature of mineralogy and textures and structures, the Garmabe Paein deposit can be divided into three different ore facies, from bottom to top: A) vein-veinlets facies (stringer zone) involving sulfide and silicic veins. Vein-veinlets and replacement textures are main features of this facies. This facies mineralogicaly, contain pyrite, chalcopyrite, and minor magnetite. B) Massive ore facies, forms thicker and higher grade part and has stratabound to stratiform nature. Mineralogicaly this facies comprised of pyrite, chalcopyrite, and magnetite, showing massive, replacement, vein-veinlets and brecciated textures. C) Bedded ore facies, located in the eastern part of the deposit, is thinner than the massive ore facies and is characterized by laxyered and banded features and low grade ore. The host rock of this facies is tuffaceous siltstone. The ores occur as laminated and banded sulfides concordant with the host rocks laxyering. Stratiform geometry is the main character of this facies. This facies is dominated by pyrite. Chloritization, silicification, and argillitization are the main hydrothermal alterations in the study area. However, the argillite alteration extends in the surface. In according to geochemical study, tectonic setting of the Garmabe Paein and Asbkeshann deposits was an extensional back- arc basin zone. Major oxides content, REE pattern and trace element variations of the volcanic rocks of host sequence display calc-alkaline nature, and basalt- rhyolitic compositions. The average grades of gold and silver in the stratiform part of the deposit is 0.5 and 9 ppm, respectively. The highest grades of gold and silver are 1 and 19 ppm. The highest amount of copper in the Garmabe Paein deposit is 1 %, with average of 0.4 %. There is a high correlation among Au, Ag and 040 Cu. Also, electron probe micro analysis (EPMA( on chlorites from the footwall altered volcanics indicate that Fe-rich chlorites are dominant. Fluid inclusion studies reveal that the dominant inclusion are of two phases (liquid and vapor), with low salinity (0.6 – 3.39 wt. % NaCl), and low homogenization temperatures (Th)(254 0C). The most important characteristics of mineralization at the Garmabe Paein deposit such as tectonic setting, host rocks, mineralogy, mextal content and mextal zonation, as well as wall rock alteration, show the most similarities with the volcanogenic massive sulfide (VMS) deposits. Accordingly, the Garmabe Paein Cu-Ag and Asbkeshan deposits could be classified as Besshi- or pelitic mafic-type VMS deposits.
