Analysis of the nature of mineralization and metasomatite zoning for known porphyry copper fields of the Goshgarchay ore-magmatic system (OMS) associated with the Murovdag group of intrusions. Complex structural-geological, metallogenic, geological-petrological, ore-metasomatic, petrochemical pa-rameters of metasomatites and studies taking into account earlier scientific-thematic, geological explora-tion works were used. There is certain regularity between the petrochemical parameters of metasoma-tites and the copper and molybdenum contents. It has been established that the thickness of metasomati-cally altered rock zones ranges from several meters to tens and sometimes even hundreds of meters (at the intersections of differently oriented faults) within the Goshgarchay OMS. Their length is measured from 500-1000 to 2000-3000m. There are three elliptical metasomatic zones, gradually replacing each other in space, surrounding the intrusive massif of porphyry composition around the ore-generating intru-sions of the Goshgarchay OMS. The inner zone, covering the endocontact and apical parts of the porphyry intrusion, is represented by intensely silicified rocks, almost completely transformed into secondary quartz-ites. The middle zone is distinguished as quartz-sericite-chlorite facies of secondary quartzites. The third, external zone of the metasomatic column is represented by the propylitic facies of secondary quartzites. Ore zoning was studied within the contours of the Goshgarchay field, and the following series of zoning of elements vertically (from bottom to top) was obtained: Mo→Cu→Со→Ni→Cr→Ag→Pb→Zn. Hydrother-mal-metasomatic alteration of host rocks in zones of different types of metasomatites formed during the formation of the field were investigated and compared based on petrochemical data.
