Abstract—The article discusses the distribution of rare-earth elements in the igneous and metasomatic rocks of the Murovdag ore district of the Lesser Caucasus. It has been established that the metasomatites and host rocks of the Murovdag ore district are characterized by the predominance of light rare-earth elements over heavy ones. The whole complex of the data obtained indicates that the components of the magmatic nature prevailed in the composition of the ore-forming fluids. However, mixing of magmatic fluids with meteoric waters is not excluded. It has been found that metasomatites and host magmatic rocks of the studied deposits have similar REE distribution patterns, which may indicate that metasomatic rocks were developed after igneous protolith of this composition.
