Hi Woohyun, thank you for your wonderful video presentation! Well done. The images you presented are very nice and show very interesting details of mineral growth and regrowth. Do you see any textural evidence of dissolution too? I'm curious if the W (and REEs) gets redistributed with the overprinting phases of alteration? I'm not familiar with scheelite CL imaging, but I wonder if you can learn even more with spectral CL imaging, which I've found to be very helpful for showing complex details in apatite. I'm also curious about what the relative MREE enrichment in the outer rim means. We've seen an analogous behavior in apatite from IOA deposits, and it seems to signal a change in fluid salinity and pH (LREEs become more soluble in Cl-rich, later fluids, and dissolution of other silicates with lower pH releases other REEs). Thanks! -Celeste
