Photographer ID's (lower case).
Identification: WDS analysis of four different Chickering Mine apatites (blue massive, lavender prismatic, milky tabular, and botryoidal) confirmed all were fluorapatite. I [tm] recognize the official Apatite-(CaF) species name has reverted to Fluorapatite. In the alphabetical order sense, most mineral collectors think of "Apatite" first, before refinement to fluorapatite or hydroxylapatite. For this reason the Apatite-(CaF) and Apatite-(CaOH) nomenclature is used here.
Discussion: APA_1: This apatite fluoresces orange in SW UV and red in LW UV.
APA_4, APA_5: TM, BJ and others collected many specimens of these lavender-colored prismatic apatites from a quartz core zone in the center of the pit during 2004.
