Highlights

The Kudeerte gold deposit is a medium-sized gold deposit newly discovered in the western section of East Kunlun.Granodiorite is the host rock of gold deposit,but the petrogenesis,tectonic background and its relationship with mineralization are still unclear.The above questions have been discussed by studying the petrogeochemistry,U-Pb zircon geochronology,and Hf isotopes of the granodiorite in Kudeerte.The petrogeochemical characteristics show that the Kudeerte granodiorite is a set of quasi-aluminum-potassium basalt rocks,showing a right-inclined distribution pattern of light rare earth enrichment,with obvious negative Eu anoalies.The relative enrichment of elements such as large-ion lithophile elements Rb and K,the active incompatible elements Th and U,the depleted high field strength (Nb,Ta,Ti),HREE,and Sr elements,with the characteristics of shell-derived magma.Zircon LA-ICP-MS U-Pb dating showes that the age of granodiorite was (242.9±1.3)Ma(n=20,MSWD=0.65).The Kudeerte granodiorite is a Ⅰ-type granitic rock series of aluminous high potassium calc-alkaline rocks formed in the Middle Triassic.The tectonic environment is the transition environment between subduction and collision of oceanic plate.
