Origin and evolution of ore-forming fluids of the Larong W-(Mo) deposit, eastern Tibet: Constraints from fluid inclusions, H-O isotopes, and scheelite geochemistry

The Larong porphyry W-(Mo) deposit, formed in the main collisional orogenic stage of Lhasa and Qiangtang terranes, is the first-discovered giant W-(Mo) deposit in the Leiwuqi-Zogang metallogenic belt, Sanjiang region. The W-Mo mineralization occurs as veins and stock-works mainly hosted in the granodiorite porphyry, monzogranite porphyry, biotite granite porphyry, and surrounding schist. Four types of fluid inclusions (FIs) including PC-type...
