| Abstract: | The large-scale Sharang porphyry molybdenum deposit,as the firstly discovered single molybdenum porphyry-type deposit in the Gangdese metallogenic belt,formed in the main-stage of India-Asia continental collision with distinct characteristics of alteration and mineralization.The alteration types include potassic-silicate alteration(K-feldspathization and biotitization),chlorite-epidote alteration,silicification,phyllic alteration(quartz-sericite-pyrite alteration)and argillic alteration(mainly Kaolinitizati... |
