Magmatic process recorded in plagioclase at the Baogutu reduced porphyry Cu deposit, western Junggar, NW-China

• Few studies have discussed the evidence of magma recharge at porphyry Cu deposit. • Elemental and Sr isotopic compositions of plagioclases indicate magma recharge. • A maximum crystal residence time of ∼300years is estimated by tracer diffusion. • Injection of more mafic magma may add Cu to the Ba...
