Zircon U–Pb geochronology and geochemistry of the Late Jurassic granite porphyries from central‐eastern Jilin Province, NE China: Petrogenesis and tectonic implications

Abstract

The recently discovered Yizuoying Mo deposit is located in central-eastern Jilin Province, NE China. The molybdenum (Mo) mineralization, mainly hosted in granite porphyry, is considered to be granite-related. Zircon U-Pb dating of the granite porphyry yielded concordant ages of 160.81 ± 0.62 Ma, which is consistent with the weighted mean U-Pb age of 160.53 ± 0.65 Ma, indicating that the emplacement of granitic plutons occurred in the Late Jurassic. The granite porphyry samples are peraluminous, high-K calc-alkaline and show an A-type geochemical signature with high
