Dictionary > Whitlockite


Whitlockite chemical formula: Ca9 (MgFe)(PO4)6PO3OH is a form of calcium phosphate that is present naturally in phosphate rock deposits, guano caves, chondrite meteorites, and granitic pegmatites.(1) It is also present in living things, including humans. In the human body, it is located in calcified tissues, such as in hypermineralized osteocyte lacunae of alveolar bone. It is also found in trace amounts in tuberculosis lesions and urinary calculi. The mineral got its name from its discoverer, Herbert Percy Whitlock (1868 – 1948), an American mineralogist. Synonym: tribasic calcium phosphate.
