Hello Jian-Wei, thank you for your presentation! I'm impressed with the utility of this metamorphic monazite application, well-presented! I'm surprised at how small some of those monazites are that you analyzed. Can you talk a bit about the precision of this technique and what limitations it may have? Do you have to worry about zoning or alteration in monazite? The M-II monazite is texturally very different than M-I and M-III generations, what does this tell you about the M-II event? Given your new data, how would you update the bi-modal magmatism hypothesis? Thanks! -Celeste

Hi Jian-Wei, thank you for the nice work. I understand the M-III monazite is hydrothermal, from fluids from the same suite of the Tin granite! Can you say something more about this 1000Ma event? Are there pegmatites of this age?
