摘要

•Improved age constrains on metavolcanic rocks in Bergslagen, Fennoscandian shield.•The Zinkgruvan Zn-Pb-Ag deposit constrained to c. 1.90–1.89 Ga using SIMS U-Pb zircon dating.•Felsic volcanism in the Zinkgruvan area ended earlier than elsewhere in Bergslagen.•World-class sediment-hosted Zn deposits could form at c. 1.90 Ga.
