摘要

•PTX and stable isotope data for Au-Bi intrusion-related deposits of North-East Russia.•Au-Bi mineralisation was mainly formed at 400–250 °C and 0.1–1.9 kbar.•Brine and CO2-rich FIs coexist at shallow level, CO2-rich FIs occur at depth.•Magmatic fluid was enriched with light O, C and S isotopes due to fluid immiscibility.
