Records of apatite for multiple injections of magmas in adakitic plutons: A case study of Mesozoic plutons in the Shatanjiao region of the Tongling ore cluster, south China

•Apatite from adakitic plutonic rocks has distinctly high Sr/Y, Eu/Eu* and La/Yb ratios.•Apatite from plutonic rocks has compositions related to that of host magmas.•Compositional variation of apatite can be used to unravel the magma evolution.
