•The collision-related granites are ~ 595 Ma to ~ 590 Ma.•The older rocks are magnesian and the younger rocks are ferroan.•The magnesian rocks are derived from a subduction-modified mantle source.•The ferroan rocks are derived by partial melting of Mesoproterozoic crust.•The granites record the tran...
