Lower crustal contribution to the magma formation of the Damiao massif-type anorthosite, North China Craton: Evidence from zircon Hf-O isotopes

•Zircon Hf-O isotopes reveal decoupling of mantle-like δ18O values (5.1–7.4) and ancient crustal-like εHf(T) values (−4.0 to −8.9).•Zircon U-Pb age of Damiao anorthosite and regional age correlation suggest that the anorthosite was emplaced in an anorogenic extensional setting.•Compilation of Sr-Nd-O isotopic data of massif-type anorthosites indicate important lower crustal input in their magma sources.
