Mineralization of the Daolundaba Cu–Sn–W–Ag deposit in the southern Great Xing'an Range, China: Constraints from geochronology, geochemistry, and Hf isotope

•Both the Daolundaba deposit and the Zhangjiayingzi intrusion formed at ca. 134–137 Ma.•The Zhangjiayingzi intrusion belongs to highly fractionated granite.•The Zhangjiayingzi intrusion formed by partial melting of a Neoproterozoic juvenile crust.•Fractional crystallization is responsible for the formation of the intrusion and the deposit.
