Characteristics of REEs and trace elements in scheelite from the Zhuxi W deposit, South China: Implications for the ore-forming conditions and processes

•Three main types of scheelite are recognized in the Zhuxi W deposit.•Different types of scheelite have distinct REE patterns and Mo contents.•Eu anomalies and Mo contents of scheelite are closed related to redox conditions.•REE patterns suggest most metals in the ores were derived from granitic magma.
