11. Apatite , augite and opaque mineral inclusions are also found.12. Common sedimentary authigenic minerals include calcium carbonate, apatite , and clays. 13. Ore minerals are coffinite, uraninite, and uranium-bearing apatite . 14. OCP could one day replace HAP and has an apatite crystal structure. 15. The calcium hydroxy apatite has the potential for prosthetic applications. 16. Some phosphates ( mainly apatite ) may also be present. 17. The deposit also contains lesser phosphate mineralisation associated with apatite . 18. Inclusions in the kimberlite include skeletal apatite , stellate aragonite and calcite. 19. Inclusions of apatite , monazite and zircon are also contained in allanite. 20. Other rocks includes clinopyroxene, titanite, apatite and feldspar.
