Apatite-(CaOH) : Ca5[OH|(PO4)3], Orthoclase : K[AlSi3O8] | |
|
Sapo mine, Conselheiro Pena, Doce valley, Minas Gerais, Southeast Region, Brazil This Apatite has finally been correctly identified as the species Hydroxylapatite, very less common than Fluorapatite. Crystals, on a matrix of Orthoclase, are flat hexagonal dipyramids with almost no prism faces, a habit that is not often seen with Apatite. Faces of a short prism can be seen on this crystal, a rarity with this material. The ... |
