The metallogenic regularity of the central Jilin- Yanbian metallogenic belt related to Yanshanian magmatism were analyzed and summarized based on the study of tectonic- magmatic evolution and ore deposit metallogenic series theory. The study shows that due to the subduction direction and velocity of the ancient Pacific plate, the complex Yanshanian tectonic- magmatic activity in the central Jilin- Yanbian area can be divided into five diagenetic and mineralizing events: (1) the late Triassic intrusion of mafic- ultramafic rocks that led to the formation of magmatic deposits such as Hongqiling copper- nickel deposit; (2) the late Triassic to early Jurassic high- potassium calcium- alkali magmatic activity in the Jizhong area and the formation of magmatic hydrothermal deposits such as the Lanjia Gold deposit, and the low potassium calcium alkali- high potassium calcium alkali magmatic activities in Yanbian resulting in the formation of volcanic- subvolcanic rock type deposits such as Qianshan gold deposit; (3) the early Jurassic to the middle Jurassic aluminum- rich acidic magma activity and the formation of porphyry molybdenum deposits such as Daheishan molybdenum deposit; (4) the middle Jurassic to late Jurassic was marked by uplift and erosion in the research area resulting in weak diagenesis and mineralization; (5) the late Jurassic to the early Cretaceous high- potassium calcium- alkali magmatic activity in the Jizhong area, and the formation of magmatic hydrothermal deposits such as the Erdaodianzi gold deposit; low- potassium calcium- alkali and high- potassium- calcium- alkali magmatic activity in the Yanbian leading to formation of volcano- porphyry deposits such as the Xiaoxinancha gold- copper deposit. Based on the establishment of the ore- forming series of magmatic processes during the Yanshanian period in the Jizhong- Yanbian area, they are further divided into 6metallogenic subseries. Despite geospatial and temporal differenes, the subseries are related indicating the complexity of the mineralization process.
