Note: I do have more aliquots of MRC and BRZ apatite, but they are not from the original crystals reported in the Chemical Geology paper. If you are interested in obtaining aliquots for your lab, please contact me. Unfortunately, there are no funds for shipping, so I ask that people provide a Fedex/UPS code or a shipping label.
