Apatite group
The Apatite group is compromised of minerals that are isomorphous hexagonal phosphates. The members of this group intermingle with one another,
within limits.
The most common member is Apatite,
which is a group in itself containing three minerals:
Apatite-(CaF)
|
Ca5(PO4)3F |
| Apatite-(CaCl) |
Ca5(PO4)3Cl |
| Apatite-(CaOH) |
Ca5(PO4)3OH |
Three other well-known members of the Apatite mineral group
discussed in this guide are:
