Apatite
Mineral Group: PHOSPHATES
| |||||||||||||||||||||||||||
| Apatite is a mineral that used to
be used as a source of fertilizers. Today other minerals are used for
fertilizers. In Ontario, apatite is no longer being mined for
fertilizer. Apatite minerals form gemmy, colorful, hexagonal crystals. Its use for jewellery is mainly limited to earrings because it is soft and brittle. Rockhounds enjoy collecting apatite crystals because large, well formed crystals can be found. |

Apatite
crystals often grow in clusters. This cluster of apatites shows how the
crystals grow because the calcite that used to be around the minerals
has been leached away by water in the soil.
Mineral crystals like these apatite crystals and black mica are often found inside massive deposits of other minerals. In this case they are in pink calcite. In Eganville, Ontario apatite crystals are mainly red though there are also green apatite crystals that are quite gemmy. Other minerals found in this formation are biotite mica, titanite, feldspar and pink calcite.
