Apatite is a mineral that is commonly found in igneous, metamorphic, and sedimentary rocks. It is made up of calcium phosphate, which is the same mineral that makes up our teeth and bones. Apatite can be identified by its green, blue, or yellow color, and its hardness of 5 on the Mohs scale. It can also be identified by its crystal structure ...

Apatite should be also scratched by steel knife (up to 5.5) and glass (up to 6). is equal to 5, i.e. corresponds to apatite. Fig. 14. Specimen of apatite from Sljudjanka, Bajkal (a) shows white color of scratch (b). The sample can be also scratched by minerals with hardness ≥6 (feldspar and higher) on the Mohs scale (c).
Apatite is a superb mineral by which to investigate the nature of fluids that have passed through and altered a rock (metasomatic processes). Its ubiquity allows it to act as a reservoir for P, F, Cl, OH, CO2, and the rare earth elements. It is also a powerful thermochronometer and can be chemically altered by aqueous brines (NaCl–KCl–CaCl2 ...

1. Introduction. Biological apatite is an inorganic calcium phosphate salt (CaPs) in apatite form with a biological derivation. As the main inorganic component of both bones and teeth, it is distributed in the organic constituents with certain sequence and direction [].By serving as the fillers in such biological tissues, biological apatite is critical …

2.1.1. Igneous apatite geochemistry. In magmatic rocks apatite is a minor yet ubiquitous accessory phase. Apatite is occasionally a rock forming mineral in some cumulates and rare igneous rock types such as nelsonites and certain pegmatites (Piccoli and Candela, 2002), while it may be absent in some S-type granitoids in which the high solubility of …

Sammite: The Strontian-rich Apatite variety is excellent for psychic vision, astral travel, and divination. It may show yellow, peach, brown, white, black, or brown colors. Staffelite: The botryoidal type of Apatite is named after its origin area of Staffel in Germany. It's great for focus, memory, and brain power.
Various other complex ions have been inferred and/or reported to be part of the biological apatite's crystal lattice, such as "labile CO 3 2− ", "non-apatitic CO 3 2− ", "labile PO 4 3− ", "labile HPO 4 2− ", and "non-apatitic HPO 4 2− " (e.g., [30], [34], [43], [44], [45]).In contradiction to the claims that these ionic entities are part of the crystalline bone ...

When the pH of apatite (Ca 5 (PO 4) 3 (F,Cl,OH)) and calcite (CaCO 3) pulp is less than 9.8, the CO 3 2-dissolved on calcite will precipitate CaCO 3 on the surface of apatite, increasing the similarity between the surface chemistry of apatite and calcite and posing difficulties for flotation separation [17], [18], [19]. Numerous studies have ...
