My Mineral Collection, Miscellaneous Systematic Phosphates, Arsenates, & Vanadates Page

These are my phosphates, arsenates, and vanadates. There are hundreds of phosphates but only a relative few of them are common. For some reason the current mineral classification scheme limits vanadates to only ortho- and pyrovanadates - all of the other vanadates are now classed with the oxides. I have not yet realigned my collection so you will find some hexa- and decavanadates on this page.
Phosphates on Other Pages
Brazilianite, florencite, and turquoise are on my gemstones page. Arthurite, calciovolborthite, chalcophyllite, chenevixite, clinoclase, clinotyrolite, conichalcite, cornetite, cornubite, cornwallite, euchroite, lammerite, lavendulan, lemanskiite, libethenite, liroconite, ludjibaite, luetheite, mixite, nissonite, olivenite, parnauite, philipsburgite, pseudomalachite, richelsdorfite, sampleite, strashimirite, tyrolite, vesignieite, veszelyite, and volborthite are on my copper minerals page.

Alvanite A rich micro of sea-green alvanite (a hydrated aluminum zinc nickel hydroxyvanadate) rosettes on vanadian black shale from the type locality of the Kurumsak V Deposit, Aksumbe, Karatau Range, Southern Kazakhstan Province, Kazakhstan. Thanks to Pavel Kartasov's auction on eBay for the specimen and the images!	Amblygonite A thumbnail of gemmy light-yellow amblygonite (lithium sodium aluminum fluorohydroxyphosphate) - this cuttable piece comes from Galiléia, Governador Valadares, Minas Gerais, Brazil. It forms two series; one with montebrasite, its hydroxyfluorophosphate analog, and one with natramblygonite where sodium predominates over lithium. Thanks to Robert Stoufer's auction on eBay for the specimen and the image!
Row 3
Anapaite This miniature of anapaite (a calcium iron phosphate tetrahydrate) on ironstone from Kertch (1988) on the Crimean Peninsula, Ukraine is a typical green iron mineral - what looks like needles are actually the top surfaces of vertically-oriented blades. It's named after Anapa, also in Russia and often occurs on fossil shells, which probably supplied the calcium. Thanks to Dave Hayward at Lucky Strike Minerals for the specimen and the image!	Angastonite Snow-white coatings of angastonite (a hydrated aluminum calcium magnesium hydroxyphosphate) on a dark matrix comprise this micro from the type locality of the Penrice marble quarry, Angaston, Barossa Valley, North Mt Lofty Ranges, South Australia, Australia. Thanks to Helmut Braith's auction on eBay for the specimen and the images!	Annabergite Annabergite (nickel (II) arsenate octahydrate) forms a complete series with erythrite. When there's more nickel than cobalt, green annabergite is formed - this thumbnail's from Laurion, Greece. Usually annabergite occurs as a dusty coating or fine tabular crystals; spheric aggregates like this are rare. Annabergite, or "nickel bloom", is used as a marker for nickel deposits. It's the arsenate analog of arupite. Thanks to Adam Larson at Adam's Mineralsfor the specimen!
Row 4
Annabergite, var. Cabrerite Bright green oriented tabular gemmy crystals of cabrerite (the magnesian variety of annabergite) comprise this thumbnail, also from Laurion. The larger image (center, right) also shows a beautiful white rosette with cabrerite "leaves"! Thanks to Mike Keim at Marin Minerals for the specimen and the images!	Apatite Beautiful green apatites, calcium (fluoro, chloro, hydroxyl) phosphate, on a cluster of green muscovite from Lavra Aldeia do Eme, Brazil. The mineral is more correctly called flurorapatite, chloroapatite, or hydroxyapatite depending on which of the three cations predominate - because a precise chemical analysis is needed, the mineral is usually just named apatite. Most apatite is flurorapatite. Thanks to Greg Holland at the Stone Haven Mineral Shoppe for the specimen and the image!	Apatite on Galena This is a beautiful specimen of fluorapatite on galena from the Julcani Mine, Huancavelica Department, Peru. The bright fluorescence is also very interesting - zonal with light orange mid-crystal and light blue on the terminations! Thanks to IC Minerals for the specimen and the image!
Row 5
Apatite Apatite can be used as jewelry although its softness precludes any use other than earrings or necklaces. These are heavily fractured so they wouldn't be cut anyway (except for the one on the right - there's probably one or two carat's worth in that one). Because of its high phosphorus content, apatite is often ground up for fertilizer. These are from Mexico - I have a bunch of them; these are the best two.	Apatite A very pale violet apatite from the MacKenzie Mountains, near Tungsten, Northwest Territory, Canada. Thanks to Doug Miller at Northern Lights Minerals for the specimen!	Apatite A beautiful one-inch long doubly-terminated blue apatite, probably from Brazil - the closeup shows one of the many blue internal reflections.

Thanks to Bill Awald's auction on eBay for the specimen and the images!	Apatite, var. Mn-bearing Apatite At the other end of the purple intensity scale lies these beautiful pale lavender tabular apatites from Pakistan. This is the variety called manganian apatite - a tiny amount of Mn+3 creates the color and makes them highly fluorescent (golden yellow) under longwave UV (larger image, bottom right). There are also tiny colorless (non-fluorescing) prismatic apatites (larger image, bottom left) scattered on the albite (miniature) matrix. Thanks to Tony Laurano's auction on eBay for the specimen!
Row 15
Apatite, var. Mn-bearing Apatite As with my previous manganian apatite at left, this apatite also includes a tiny amount of manganese - this time, it's the Mn+5 ion and that makes it a deep blue. This 13mm crystal is from Ipira, Brazil - my other Ipiran blue apatite is probably manganian as well. There's one other color that manganese imparts to apatites - Mn+2 with a little iron makes a distinctive green apatite. Thanks to Alexander Falster's auction on eBay for the specimen!	Arrojadite-(BaFe) A small-cabinet specimen of massive brown arrojadite-(BaFe) from the Tip Top pegmatite, Fourmile, Custer County, South Dakota. I don't know what the dark-green veins are.

Whiteite Beautiful tan crystals of whiteite (an aluminum magnesium hydroxyphosphate with traces of calcium, iron, and manganese) - there's actually three whiteites; this one's probably whiteite-(CaFeMg). There's also tiny quartz, lazulite, and augelite crystals. This miniature is from Rapid Creek, Yukon, Canada. Thanks to Dave Hayward at Lucky Strike Minerals for the specimen and the image!	Whiteite-(CaFeMg) A 15mm whiteite-(CaFeMg) crystal from Crosscut Creek, Area 1 (Kulan Camp), Rapid Creek, Dawson Mining District, Yukon Territory, Canada. Thanks to Reiner Mielke's auction on eBay for the specimen and the images!	Whitlockite An interesting miniature of whitlockite (a calcium iron magnesium hydroxyphosphate) crystals on matrix from Rapid Creek, Yukon, Canada. The larger image shows gormanite inclusions (bottom right) and a kulanite rosette (bottom left). Thanks to Jonathan Levinger's auction on eBay for the specimen and identifications!
Row 124
Whitlockite An excellent small-cabinet specimen of pale-pink whitlockite lining a vug in massive quartz from the Tip Top Mine, Fourmile, Custer District, Custer County, South Dakota. There's also some reddish-black robertsite present. Thanks to Chris Korpi's auction on eBay for the specimen and the image!	Whitmoreite A busy thumbnail of phosphates from the Hagendorf South Pegmatite, Waidhaus, Upper Palatinate, Bavaria, Germany. In addition to yellow-brown whitmoreite (larger image, top right), there's also yellow-orange laueite (larger image, bottom left) and pale-yellow strunzite (larger image, bottom right). Whitmoreite is a hydrated ferrosoferric hydroxyphosphate and is the phosphate analog of bendadaite. Thanks to Paolo Bracci's auction on eBay for the specimen and the image!	Wolfeite A miniature chunk of wolfeite, a rare iron manganese hydroxyphosphate, from the Big Fish River area, Yukon, Canada. It forms a series with triploidite. Thanks to Tom Klinepeter's auction on eBay for the specimen!
Row 125
Wolfeite Another miniature of mixed phosphates from the Big Fish River area. Predominated by reddish-brown wolfeite, this specimen also includes golden-brown satterlyite (larger image, bottom row center) and minor maricite (larger image, bottom row right). There's also pyrite and vivianite present. Thanks to Jake Slagle's Maryland Minerals auction on eBay for the specimen and the image!	Xanthoxenite A rich thumbnail of light-golden-brown xanthoxenite (a hydrated calcium iron hydroxyphosphate) on matrix from the type locality of the Palermo No. 1 Mine, Groton, Grafton County, New Hampshire. It's a secondary phosphate created by hydrothermal reworking of triphylite. Thanks to Jake Slagle's Maryland Minerals auction on eBay for the specimen and image!	Xenotime-(Y) This is a beautiful thumbnail crystal of color-change (larger image) xenotime-(Y) from Zagi Mountain, NNW of Peshawar, NWFP, Pakistan. It forms a complete series with chernovite-(Y), its arsenate analog and an incomplete series with xenotime-(Yb), its ytterbium analog. These came from a (now-depleted) single-pocket find of only a few dozen specimens in Spring 2003. Thanks to Rob Lavinsky at The Arkenstone for the specimen and the image!
Row 126
Xenotime-(Y) A 2cm pair of adjoined and terminated xenotime-(Y) crystals from Ibitiara, Bahia, Brazil. Both crystals show the typical c-axis curvature. Thanks to John Veevaert at Trinity Minerals for the specimen and the images!	Xenotime-(Y) A tan xenotime-(Y) crystal from Evje og Hornnes, Aust-Agder, Norway. This crystal is almost entirely missing its prismatic "sides". Thanks to Paolo Bracci's auction on eBay for the specimen and the image!	Yukonite A miniature of rare and amorphous black yukonite (a hydrated iron calcium hydroxyarsenate) on matrix collected in 1984 from the Venus Mine (near the type locality), Carcross, Near Lake Tagish, Yukon Territories, Canada. Thanks to Marty Lewadny at CrystalEnthusia (formerly Crystal Variations) for the specimen and the image!
Row 127
Zanazziite An interesting miniature of an equant light-olive-green zanazziite (a hydrated iron calcium magnesium beryllium hydroxyphosphate) crystal partially covered with gormanite needles from Minas Gerais, Brazil - it may be from the type locality of the Lavra da Ilha pegmatite. Zanazziite is a member of the roscherite group. Thanks to Adam Larson's (Adam's Minerals) auction on eBay for the specimen and the image!	Zanazziite, var. Manganoan Zanazziite An excellent micro of pink manganoan zanazziite on albite from the Jenipapo District, Itinga, Minas Gerais, Brazil. It was acquired from Luis Menezes and carefully analyzed - almost all of the iron is replaced by manganese. Thanks to Jake Slagle's Maryland Minerals auction on eBay for the specimen and the image!	Zýkaite A miniature of grayish-white zýkaite (a hydrated ferric hydroxysulfatoarsenate) with gypsum and yellowish kankite from the type locality of the Safary mine, Kank, Kutná Hora, Bohemia, Czech Republic. Thanks to Tony Nikischer at the Excalibur Mineral Company for the specimen!
