| Abstract: | The Mingze porphyry Mo deposit is located in the southeastern margin of the Gandese metallogenic belt,north of the Yarlung Zangbo River suture zone.A variety of intrusions outcrop such as moyite,biotite monzogranite,granodiorite,porphyaceous adamellite and granite porphyry.The granite porphyry is the ore-froming related intrusion which is completely mineralized.Wall rocks suffered extensive alteration,mainly as potassic,silicification,chloritization,kaolinization and skarn alteration.Various types of altera... |
