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!

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!

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 2

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.

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 3

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.

Thanks to Bill Awald's auction on eBay for the specimen and the images!

Apatite, var.
Manganian 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!

An excellent miniature of sphericular greenish-blue arsenogorceixite (a barium aluminum hydroxyarsenate) on matrix from the type locality of the Clara Mine, Rankach valley, Oberwolfach, Wolfach, Black Forest, Baden-Württemberg, Germany. This may be the cuprian variety - arsenogorceixite is more typically white to yellow. It may form a series with weilerite where sulfate replaces part of the arsenate cation though some references consider weilerite to be merely a synonym. Also, the formula for arsenogorceixite varies among references - I count at least three.

Thanks to Sönke Stolze's Systematic-Minerals.com>/a> auction on eBay for the specimen and the images!

Fernandinite
on
Corvusite

The dark-green fernandinite (a hydrated calcium sodium potassium vanadate) fibers are almost impossible to see (in my poor photo) against the black corvusite (a hydrated sodium calcium potassium vanadate) matrix in this thumbnail from the type locality for corvusite, the Uravan District, Montrose County, Colorado. The larger image shows a second thumbnail. Ex: David Shannon collection (Aug 1990). Corvusite and fernandinite form an incomplete series with sodium or calcium predominating. Also, because vanadium has two valences in these two minerals, V (III) and V (V), they should rightly be called mixed oxides instead of vanadates. There are many formulas for these two minerals - some of them include a small amount of ferrous iron.

Thanks to Anthony Jones' auction on eBay for the specimen!

Row 29

Ferrisicklerite

A cleavage fragment of ferrisicklerite from the Buzzos Mine, Center Strafford, Stafford County, New Hampshire. It forms a series with sicklerite (manganese-rich lithium phosphate; ferrisicklerite being the other, iron-rich member).

Thanks to Chris Wong's auction on eBay for the specimen!

Ferrostrunzite

An excellent miniature of ferrostrunzite on matrix from Blaton, Hainaut Province, Belgium. The specimen label says ferrostrunzite - according to the MinDat database, ferrostrunzite doesn't occur there. Ferristrunzite does, in fact, this is the type locality for ferristrunzite.

Thanks to Steve & Susan Bringe's (Summit Minerals) auction on eBay for the specimen and the image!

Fluellite

Here's an excellent thumbnail of bright white druse of fluellite, a hydrated aluminum hydroxyfluorophosphate, on matrix from the famous Willard Mine, Lovelock, Pershing County, Nevada.

Metaswitzerite

Tiny radial sprays of rusty-red metaswitzerite (a manganese phosphate tetrahydrate) on a quartz matriz from the type locality of the Foote Lithium Mine, Kings Mountain, Cleveland County, North Carolina. This was originally sold as and thought to be switzerite, the heptahydrate. Studies have shown that switzerite irreversibly dehydrates (sometimes violently) in a few minutes of exposure to air to metaswitzerite. It can safely be said that all switzerite in collections is metaswitzerite. Also, even though most formulas don't show it, metaswitzerite contains a few percent of ferric and ferrous iron.

Straczekite

Tiny black specks of straczekite (a calcium barium potassium vanadate) on a thumbnail matrix from the type locality of the North Wilson pit at the Union Carbide Mine, Potash Sulfur Springs, Garland County, Arkansas. Straczekite is the namesake of one of the two fibrous "vanadium bronze" mineral groups, which also includes bariandite, bokite, corvusite, and fernandinite. Vanadium bronzes are used as pigments and are being studied for catalysts, electrochromic displays, and electrochemical analytical electrodes.

Thanks to Ben Clardy's auction on eBay for the specimen!

Thanks also to Paul D. Thompson, the discoverer of straczekite, for the location correction!

Strengite

Strengite's one of the few purple iron minerals - this excellent thumbnail of strengite (ferric phosphate dihydrate) sphericules on iron ore is from Norrbotten, Sweden. It forms a series with variscite, its aluminum analog and is dimorphic with phosphosiderite.

Thanks to Jennings "Beau" Gordon's (Jendon Minerals) auction on eBay for the specimen and the image!

Taranakite (a hydrated aluminum potassium double phosphate) is a secondary phosphate found in caves and along seashores - it's the most common cave mineral. This vial of white taranakite grains is from Super Cave, Cervantes, Western Australia, Australia.

Thanks to David H. Garske's (MINERALS and MORE) auction on eBay for the specimen and the image!

Row 65

Triphylite

A large cabinet specimen of triphylite (lithium iron manganese phosphate) from the famous Palermo #1 pegmatite, North Groton, New Hampshire. It forms a complete series with lithiophilite, the manganese-rich end member, and like lithiophite, is a primary phosphate mineral - it alters into many beautiful secondary phosphates. Because of the color, this specimen may be nearer in composition to lithiophite. There's also minor muscovite and pyrite present.

Thanks to Alexander Falster's auction on eBay for the specimen!

Triploidite

This miniature of red triploidite (a manganese iron hydroxyphosphate) and beige quartz comes from the Capoeira Mine, near Parelhas, Rio Grande do Norte, Brazil. It forms a series with wolfeite where the iron predominates.

Trolleite

Trolleite's another aluminum hydroxyphosphate - here, it occurs as glassy light greenish blue masses with specular hematite and quartz. It's from Hålsjöberg, Torsby, Värmland, Sweden. I increased the color gamma a bit on these pictures - it really is beautful shades of green and blue.

Thanks to Emilie & Ron Kendig's auction on eBay for the specimen!

Row 66

Turneaureite

Turneaureite's another apatite group mineral (calcium phosphatoarsenate) - this small cabinet piece has orange patches of turneaureite and probable tiny dark-brown donpeacorite crystals. It's from the type locality (for both minerals) of the ZCA Mine #4, Balmat, St Lawrence County, New York.

Thanks to Val Collins' auction on eBay for the specimen and the image!

Wavellite

An interesting thumbnail of white wavellite on (probable) fluellite (an aluminum hydroxyfluorophosphate) on a dark matrix from the Willard Mine (one of the best U. S. locales for fluellite) in Pershing County, Nevada.

Row 74

Wavellite

The vast majority of wavellite is green - here's a beautiful yellow miniature from (probably the) Crystal Baron Mine, Crows, Saline County, Arkansas. It also fluoresces a beautiful apple green thanks to a microscopic coating of pure (iron-free and colorless) wavellite. (A trace of iron quenches the fluorescence in almost all wavellite.)

Thanks to Anne & Charles Steuart's auction on eBay for the specimen!
Thanks also to J. Michael (Mike) Howard, Rockhounding Arkansas, for the fluorescence info!
