Thank you very much for the talk, a lot of interesting data here! A couple of questions: 1) What are the differences in bulk compositions for the apatites that you grouped into A, B and C? Each produces strikingly different apatite-bulk rock partitioning values, which do you think is closest to an apatite/melt partition coefficient? 2) In systems that contain titanite, do you see multiple populations of apatite that record pre- and syn-titanite REE patterns (i.e., when titanite is present, does it tend to crystallize before, during or after apatite crystallization)? 3) Do these trace element variations also correspond with variations in the OH, F, Cl content of the apatites?
