A CO 2 -rich porphyry ore-forming fluid system constrained from a combined cathodoluminescence imaging and fluid inclusion studies of quartz veins from the Tongcun Mo deposit, South China

The Tongcun deposit is a medium-sized porphyry Mo deposit in the eastern section of the Qin-Hang metallogenic belt, South China. Fluid inclusions and scanning electron microscope -cathodoluminescence (SEM-CL) of different generations of quartz from multi-stage veins were studied to reconstruct the evolution of the porphyry hydrothermal system at the Tongcun Mo deposit. Four stages of hydrothermal veins were recognized at Tongcun, including the...
