Apatite

This page kindly sponsored by Matt Zukowski
System:
Hexagonal
Hardness:
5
Name:
From the Greek the greek ἀπατάω (apatao), to deceive or to be misleading, as apatite was often confused with other minerals (e.g. beryl, milarite).
"Apatite" is a field term for unidentified calcium phosphate members of the apatite group.
Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare.

"Apatite" crystals are short to long hexagonal prisms [0001], with {1010} and {1011} dominant; also thick tabular {0001}, frequently in the crystals of hydrothermal origin in pegmatites and veins, with {1010}, relatively large {0001}, and often also {1011} or low pyramids. Massive, coarse granular to compact. Globular or reniform at times with a sub-fibrous, scaly, or imperfectly columnar structure or as fibrous crusts; stalactitic; earthy; oolitic. May be rock-forming in beds of great extent; as nodular concretions in clays and shales; conglomeritic.

Apatite may be confused with beryl, milarite or phenakite.
