Sedimentary phosphates form only when the proper physical conditions and biological activity coincide. Once deposited, the phosphate (PO43−) crystallizes into the mineral carbonate-fluorapatite (CFA). This mineral, with substitution of CO32− for PO43−, compositionally falls between the familiar forms of fluorapatite found in igneous and metamorphic rocks and the apatites found in biological material, including our own bones and teeth. Finally, through mining and processing, it... You do not have access to this content, please speak to your institutional administrator if you feel you should have access.
