| Formula: | Ca5(PO4,CO3)3(F,O) |
| Comments: | "Attractive well-formed fluorapatite crystals are found in miarolitic cavities, particularly in the upper levels of the quarry. In general, crystals have simple hexagonal to near circular outlines, and range from tabular to blocky and, less often to prismatic. Complex terminations are absent, and crystals usually have a flat lustrous pinacoids face, often showing growth outlines. Some crystals show weakly developed low angle pyramidal faces. The prism faces are almost always striated. The largest crystal collected include tabular varieties 4.5 cm across and 1 cm thick, and prisms 2.5 cm long and 1.2 cm across. Colour in the larger crystals generally ranges from shades of dull greyish to bluish green and deep opaque blue. Most crystals show colour zoning involving these shades, as well as near colourless and pale purple zones. The most common scheme is for pale blue translucent crystals to have dark blue bands at the upper and lower pinacoids. Sparklings of smaller crystals from opaque cream or grey to colourless or transparent blue or mauve are also found. Apatite has also been found rarely at Lake Boga as lustrous, fibrous globular dark green linings to cavities." |
