Abstract

Abstract

The magmatic rock of porphyroid monzonitic granite of Xishan copper polymetallic deposit, Geermu City, is located in the Late Caledonian Qinling-Qilian-Kulun orogen between the Central and North Kunlun fault, and the research work is still very poor. Based on the rock geochemistry and isotope chronology, this paper shows that the magmatic rocks belong to high potassium calc-alkaline series and peraluminous granites. The chondrite-normalized rare earth element (REE) distribution patterns of the magmatic rocks are enriched in the light REE (LREE) and display strong negative Eu anomalies. The magmatic rocks are enriched in large ion lithophile elements (Th, U, K), while depleted in high field strength elements (e.g., P, Ti) and in Ba relative to Rb and Th. The magma is the source of the crust and has the characteristics of weakly separated crystalline granite. The U-Pb weighted age (average 267.5±3.4 Ma) and concordant age (267.0±2.9 Ma) acquired in zircon from porphyritic monzonitic granite show that the rock mass formed in middle Permian, which thus constrainted the lower limit of mineralization. The origin of the deposit should be polymetallic tectonic hydrothermal type, which was related to granitic magmatism.
