Name:
Name introduced in 1860 by Carl F. Rammelsberg, in his Handbuch der Mineralchemie. Here he reviewed some analysis of apatites, and found that apatite may have fluor(F) or chloride (Cl) as the dominant anion. An analysis of apatite from Kragerø, Norway (cited after Völker) showed 4.10 wt % Cl, and was named as chlorapatite. The name is made of the prefix, chlor, for the dominant chlorine and the Greek ἀπατάω (apatao), to deceive, as apatite was often confused with other minerals (e.g. beryl, milarite). The name was changed in 2008 to apatite-(CaCl), but was quickly reverted back to chlorapatite in 2010.
Co-Type Localities:
A chlorine-rich calcium phosphate that belongs to the apatite group. It is the chlorine analogue of fluorapatite and hydroxylapatite, the phosphate analogue of turneaureite, the Ca5 analogue of phosphohedyphane and the calcium analogue of alforsite.
Chlorapatite is formed in fluor-deficient environments, and found in calcium silicate marbles, in layered mafic intrusions and in diabases. It is known to replace triphylite in some granite pegmatites (Ptáček 2016). A monoclinic structural variant, chlorapatite-M is known.

The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
