Abstract

Based on the theoretical modelling of water-rock δD-δ18O isotopic exchange process, the evolution and sources of ore-forming fluid in four metallogenic epochs of the Jinduicheng superlarge-scale porphyry-type molybdenum deposit were investigated. It was revealed that in the pre-metallogenic and early-metallogenic epochs, the ore-forming fluid was a residual fluid derived from magmatic water-wall rock interaction at middle to high temperatures (T = 250–500°C) and lower W/R ratios (0.1> = W/R>0.001), while in the metallogenic and postmetallogenic epochs, the ore-forming fluid was a residual fluid derived from meteoric water-wall rock interaction at middle to lower temperatures (T = 150–310°C) and relatively high W/R ratios (0.5>W/R≥0.1). The meteoric water played an important role in molybdenum mineralization, and at the main metallogenic epoch the W/R ratio reached its maximum value.
