The whitlockite structure was reported by Calvo and Gopal (1975) and was treated as a glaserite: related rod packing by Moore (1981). In the present study, the atomic sites of Calvo and Gopal were assigned simpler labels. The underlying features of the structures are two distinct rods, rod I at (002) and rod II centered at
WebWhitlockite - White to colorless rhombic crystals of Whitlockite to 3mm. It is probably Bobdownsite although would need to be tested. All Whitlockites I have sendt to RRUFF have turned out to be Bobdownsite. . This and many more mineral specimens are available for sale at Dakota Matrix Minerals. WebRaman analyses at the RRUFF project has thus shown all Whitlockites from the Tip Top mine to be Bobdownsite. But there is a chance that fluorine maybe detected by inclusions of fluorapatite in the crystals. It is very difficult to distiguish F from OH with EDS without doing a polished section.
WebLustrous rhombic fine crystals of Whitlockite from 1 to 4mm in size. These are unusually large and well-defined Whitlockite crystals. They are underlain by a layer of lilac to pink carbonate apatite. The Whitlockite is also slightly pink. WebWhitlockite - An interesting specimen of Quartz matrix with a void lined with colorless Whitlockite rhombs. White carbonate apatite has been selectivley deposited on the edges of all the Whitlockite crystals. Round growths at the center are probably Rockbridgite. Layers of apatite/whitlockite can be seen along the edges. . This and many more mineral …

WebFound as a late hydrothermal mineral in granite pegmatite at the Palermo quarry, near North Groton, New Hampshire, in the following association and sequence: whitlockite and quartz—rhodochrosite—apatite—zeolite. Whitlockite is structurally distinct from graftonite, caryinite, fillowite and apatite. egph runway lengthWhitlockite is a member of the phosphate group of minerals with three distinct occurrences. For many years, these occurrences were thought to be identical. However, recent studies using x-ray and electron diffraction have been able to identify compositional differences that separate one type of whitlockite from another. There are two inorganic occurrences of whitlockite that differ chiefly by the presence or absence of hydrogen. This difference was not initially observed due to … egph atisWebApr 13, 2024 · Bone whitlockite (WH) exists in the collagen matrix along with hydroxyapatite (HA) and plays a vital role during earlier stages of bone development.
