Specimen owner ID's (capitals): TM = Tom Mortimer, BW = Bob Wilken, BJ = Bob Janules, PC = Peter Cristofono, AW = Anna Wilken
Photographer ID's (lower case).
Identification: CHI_1 => Cannon Microprobe EDS analysis
CHI_3 => Kerry Day EDS analysis
Discussion: BW originally thought mineral shown in photos MES_1, MES_2, MES_3 were messelite, but EDS analysis. does not fit. A second EDS analysis. showed a similar result. A calcium rich childrenite has been suggested. These analyses were not done on polished grains, so surface contamination (apatite?) may be present. The "MES" designations on the photos is a holdover from the original visual identification.
