Popis: Aghbolagh copper deposit is located in the southwest of West Azarbaijan Province, 10 km north of Oshnavieh city. Most of the existing rock outcrops in the area include Cambrian deposits (carbonated and clastic deposits). These deposits are metamorphosed by intrusive-granite masses (skarn-genesis). The infiltration of the mineralization solution at distances beyond contact and inside the sandstone sequences has resulted in the formation of copper ore veins. For microscopic and geochemical studies, 21 thin sections, and 22 doubly-polished cross-sections, 22 XRD specimens, 22 ICP-MS specimens, and three samples for analysis of 10 oxides were analyzed by Zarazma Corporation. In the study of the fluids involved, measurements were made using a Linkham THMSG600 heater and freezer plate, mounted on a polarized microscope with a separate stage and Olympus model. Studies on quartz minerals (3 samples) and garnet minerals (2 samples) were performed on five polished double sections by micro-thermometry measurements on 30 inclusion in quartz mineral and 15 inclusion in garnet mineral at Rizkavan Land Company. The results show that the La/Y ratio, which is a proper indicator for the pH conditions of the formation environment of ore deposit, in Aghbolagh deposit is a range from 0.09 to 2.26. The granite mass has the highest amount, and the skarn zone represents two types of conditions. Type 1: Section where the La/Y> 1 ratio observed in samples close to the skarn mass and ore. Type 2: Part where the ratio La/Y
