“…Regional magmatism includes Hercynian plutons (321-250 Ma), including quartz diorite, tonalite, granodiorite, monzogranite, gabbro, quartz monzonite, biotite granite, and K-feldspar granite [11][12][13][14][15]. Indosinian granitoids (250-225 Ma) consist of two-mica granite, granite porphyry [16,17], and granodiorite porphyry and Yanshanian intrusions (182-125 Ma) [1,4,9,[16][17][18]. In addition, the W, Sn, Pb, Zn, Cu, and Ag deposits in the region are all closely related to Indosinian and Yanshanian granites, including granodiorite, quartz syenite, K-feldspar granite, hornblende monzonite, and monzogranite [2,6,14,16,19,20].…”
