•High δ66Zn of subalkaline mafic–ultramafic intrusions was caused by decarbonation reactions between co-existing silicate and carbonates during subduction.•Decarbonation reactions are crucial for recycled carbonates in deep carbon cycling.•Accumulation of Fe-Ti oxides and olivine can lead to Zn isot...
