Nice talk! Why are Celestine deposits so rare, or in other worlds, where is the Sr coming from? Has the intrusive rock connected with the Shizilishan deposit high Sr contents? Or the surrounding limestone? You worked out nicely the hydrothermal conditions, but why not in other related deposits? Or is there Celestine in Carlin-type deposits?
Sr is easily captured by mineral containing Ca, Ba, and K due to their similar chemical features. Most of Sr may transport into water by erosion and flow into the ocean/ lakes then captured in carbonate or celestine during the sedimentary. The intrusion may have contributed minor Sr during low-temperature alteration. Most of them may derive from evaporates as celestine shows heavy S isotope (~28‰) . Celestine is not so common in Carlin-type deposits probably due to barite is more likely to precipitate when fluids have high contents of dissolved sulfate or simply is not economic enough to attract attention. However, some MVT do have enough celestine to be mined as Sr-(Pb-Zn) or Pb-Zn-Sr deposit in Tunisia and the southern part of northeastern Mexico (see González-Sánchez et al. 2009, MD; Bejaoui et al. 2014, Arab J Geosci).

From Lingli Zhou: what do you think of the role of magma intrusion in the Sr-Pb-Zn mineralization? Any metal contribution?

The intrusion may have contributed minor Sr during low-temperature alteration. But is hard to tell since the intrusion is highly altered and difficult to find fresh samples to do Sr isotope.
