'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of maghemite, hematite, lepidocrocite, hisingerite, pitticite, jarosite group species, etc. Although the images below appear to be crystals, they are only the pseudomorphs (false forms) of minerals that have been replaced by various fine grained iron minerals that are often not easy to characterize exactly and the name limonite is commonly used to describe them. The reason that we do not capitalize the L in limonite below is because it is not an IMA approved mineral name. We use it here because it has a long track record as a useful name and one that is currently commonly used. There are a few other mineral mixtures that are pseudomorphs that we treat in a similar fashion in this article for want of a better term to describe them. It may be that limonite pseudomorphs are the most common of all pseudomorphs and you can see from the very many of them below that they are indeed abundant. Sometimes these are called Goethite pseudomorphs, but I would bet a good steak dinner that most of those are in reality limonite pseudomorphs as well. limonite after Clinozoisite USA California, Riverside Co., Crestmore, Crestmore limonite after Clinozoisite 3.5mm wide© 2008, JGW limonite after Cuprite with Azurite & Malachite Greece Attikí (Attica; Attika) Prefecture, Lavrion (Laurion; Laurium) District, Lavrion District Mines, Sounion Area, Agia Varvara Mines (St Barbara Mines), Sounion Mine No. 06 ("Exi" Mine) limonite after Cuprite with Azurite & Malachite FOV 8mm© limonite after Legrandite Mexico Durango, Mun. de Mapimí, Mapimí, Ojuela Mine limonite after Legrandite ~6cm wide© limonite after Marcasite Italy Marche, Ancona Province, Fabriano, Pecorile limonite after Marcasite 1.5cm tall© limonite after Marcasite USA Missouri, Jasper Co., Tri-State District, Joplin Field limonite after Marcasite 10cm tall© Charles Creekmur limonite after Marcasite USA Missouri, Jefferson Co., Southwest Jefferson County barite and lead District limonite after Marcasite 4cm wide© Charles Calkins limonite after Marcasite USA Wisconsin, Colombia Co. limonite after Marcasite 4.9cm tall© Weinrich limonite after Pyrite (devels dice) Australia Queensland, Mt Isa - Cloncurry area, Mount Isa district, May Downs Station, Slaughteryard Creek limonite after Pyrite ~2.5cm wide© Ryan Eagle limonite after Pyrite Australia South Australia, Flinders Ranges, North Flinders Ranges, Arkaroola area limonite after Pyrite 3.8cm wide© JSS limonite after Pyrite 4.3cm wide© JSS limonite after Pyrite Australia South Australia, Flinders Ranges, North Flinders Ranges, Chambers Gorge (Mount Chambers Gorge) limonite after Pyrite FOV 4cm© Judy Rowe limonite after Pyrite Australia South Australia, Olary Province, Olary limonite after Pyrite 4cm wide© Greg Murray limonite after Pyrite Austria Styria, Fischbacher Alpen Mts, Rettenegg, Blasenkogel Mt.

In some cases the alteration is further along than others. These specimens are stable, at least in terms of not altering further in our lifetimes. These specimens were found recently, in the last ten years and their estimated stability is based on observations made on similar pseudomorphs found in Death Valley California that have been stable over the last 40 years. Certainly the Inyoite specimens from this locality are by far the finest in the world.

The tunnel only went in 50 feet or so, but in one of the little drifts off the main tunnel, a small area produces at least two outstanding pockets of these specimens. Some few hundred specimens of this material were produced. Some of the specimens still showed vestiges or the original Inyoite. The material from the bottom of the pocket tended to be coated with little micro prismatic crystals of Meyerhofferite which made them more sparkling than those from the top which tended to be be chalky white, but sharper than the crystals from the bottom of the pocket. More than 40 years out of the ground in the polluted air of Los Angles, indicates that these specimens are stable and show no signs of falling apart.

So often someone posts something like. Image X is not correct, it should be Y. Their correction could very well be correct, but the poor expert/manager/moderator often does not have a clue if this is true or not. If everyone suggesting changes would explain exactly why they believed something should be changes it would make our jobs here on mindat so much easier.

You have listed one of your photos (added on 2nd May 2010) showing a 6cm Kaolinite after Orthoclase pdeudomorph from the Keith Harshberger collection in the 'Pseudomorphs and Replacements J to M'.
The caption claims that the specimen is from the Slip China Stone Quarry, St. Dennis, St. Austell District, Cornwall. UK, and the image has the reference ID 302068.
I would opine that it is not possible that the specimen originated from Slip China Stone Quarry, the reason being that the quarry lies in the small Fluorite Granite area totally within the nonmegacrystic Lithium Mica Granite of the St. Austell Granite Mass. To my knowledge no megacrysts have been noted from there. There are two major megacrystic zones in the St. Austell Granite Mass, one a lobe in the far west, and a much larger area spanning most of the centre and eastern parts. The specimen illustrated is from one of those two zones.
As it is not possible to designate a specific china clay pit or quarry as its origin, I suggest that the caption should delete Slip China Stone Quarry, and read 'St. Austell District, Cornwall, UK..
Furthermore, the Slip China Stone Quarry lies within the parish of St. Stephen-in-Brannel and not St. Dennis as stated.

To remove the speciment from its box, and take the pics from a bigger distance, on a tripod might help!

For the Mottramite after Wulfenite I think you will need to take the specimen out of the Perky box to photograph it properly. You should easily be able to pry/lift the Styrofoam base it is attached to out of the box with little effort. Slip a knife blade in along the edge of the foam and gently pry it out with the specimen attached. Put it on some sort of white or light gray back ground and you should then be able to easily shoot it from any angle. If you can set you camera for tungsten lighting, you can use tungsten light, but if not you will need to take the picture in diffuse sun light. Use a tripod or some other device to steady your camera and make sure that the f stop is at least f16 or f22 or smaller if you can manage it. This will insure that you will get maximum depth of field. If your camera can't focus up close to the specimen, you should take the picture as close to the specimen as possible and still make sure that the specimen is in focus. How many mega pixels can your camera do for an image. Even if the specimen can't fill the screen, the image can be cropped and still show good resolution provided you are using any sort of decent camera.

However M Sussman has had hexagonal wulfenite from Tsumeb, and the calcites crystals has the typical basic shape of secondary tsumeb calcite. However, 100 % certitude is difficult to obtain!
I have one other nice Tsumeb pseudomorph, second and third pictures, cabinet, hollow hexagonal crystals up to about 2 cm, However I do not propose it as long as the composition is not known for sure (could be motramite, descloizite or many other), after what???

That's really a beautiful sample -- very nice, and puts to shame the various things I've been throwing at the wall. Even easier, though, as Rob has previously posted it to MinDat and I've linked it here: Quartz after wulfenite.

Probably should be in the "Best Pseudomorphs: Quartz" thread, though.

Per comments in "A to C", I'm posting a set of specimens that hit localities and/or replacements not well represented in the articles at present, rather than saying these are all The Best. Thank you for your efforts!


Kaolinite after leucite
Poços de Caldas, Poços de Caldas plateau, Minas Gerais, Brazil
Pseudo / loc is already represented, but this is a pretty good example.

Lazulite after orthoclase
Cerro de Potosí (Cerro Rico), Potosí City, Potosí Department, Bolivia

Leonite after picromerite
Neuhof-Ellers Potash Works, Neuhof, Fulda, Hesse, Germany

Lepidolite after elbaite
Jacare Mine, Itinga, Jequitinhonha valley, Minas Gerais, Brazil
The Jacare Mine isn’t in MinDat yet but I don’t know anything beyond the name. There are other examples of this on the locality listing as well.

Muscovite after plagioclase
Whitehorse Mining District, Yukon Territory, Canada
There are other examples of this pseudo on the locality listing as well; the other photos are more professional.

Opal after [chabazite?]
Fish Lake Valley, Mineral Co., Nevada

Orthoclase after leucite
Kamam-Kalehövük, Kırşehir Province, Central Anatolia Region, Turkey
There is another example of this pseudomorph in the gallery for this locality, but this is really nice representation.

But this is true of several hundred specimens in my collection. While I was taking pictures I concentrated on specimens I didn't have in my collection. After all, if you have the real thing in your collection, why in the world would you want to waste your time taking pictures of them when you could always just go out and look at the real thing? Sometimes I needed pictures for articles I was writing or programs I was asked to give to gem and mineral societies, so I did take a few pictures of things in my collection.]]> Rock Currier Best Minerals P Thu, 30 Dec 2010 10:18:03 +0000 http://www.mindat.org/forum.php?read,82,202977,207996#msg-207996 http://www.mindat.org/forum.php?read,82,202977,207996#msg-207996
What about the Muscovite after Apatite from Conselheiro Pena, Doce valley, Minas Gerais, Brazil. I know many were brought up. You have several in your collection.

Leonhardite after Laumontite 6cm wide	© 2010, JGW

Leonhardite is not longer considered a mineral. It is now considered a synonym of Laumontite which is not very correct either. Leonhardite was the mineral you got when Laumontite lost its water. It might be more properly be describes as a variety of Laumontite.

If you have any Leonite pseudomorphs after Picromerite on Halite or as loose crystals, you should take very good care of them because they are not very stable in most normal collection environments. Put them in a cool dry place that is not subject to fluctuations in humidity or temperature. Otherwise you may end up with a pile of little white crystal fragments.

Leucoxene is not a mineral, but rather a an alteration product and mixture of Fe-Ti oxides, including titanite, perovskite, titanian magnetite, but especially ilmenite. Most 'leucoxene' is anatase or rutile.

Limonite is the name is currently used for unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of maghemite, hematite, lepidocrocite, hisingerite, pitticite, jarosite group species, etc. Although the images below appear to be crystals, they are only the pseudomorphs (false forms) of minerals that have been replaced by various fine grained iron minerals that are often not easy to characterize exactly and the name limonite is commonly used to describe them. The reason that we do not capitalize the L in limonite below is because it is not an IMA approved mineral name. We use it here because it has a long track record as a useful name and one that is currently commonly used. There are a few other mineral mixtures that are pseudomorphs that we treat in a similar fashion in this article for want of a better term to describe them. It may be that limonite pseudomorphs are the most common of all pseudomorphs and you can see from the very many of them below that they are indeed abundant. Sometimes these are called Goethite pseudomorphs, but I would bet a good steak dinner that most of those are in reality limonite pseudomorphs as well.

As you can probably deduce from the many fine examples of Malachite after Azurite above, that Tsumeb is probably considered as having produced the best specimens of this type of pseudomorph, though Bisbee loyalists can also point to some amazing examples from Bisbee, Arizona.

The fine Malachite pseudomorphs after Azurite from Bisbee are considered to be great classics and every collector would put one in his collection if they could afford it. There are not many great ones.

These were mostly produced during the 1800s when the mines at Chessy were most active. Thousands of them were produced and though they are not nob abundant, every collector that wants one can get one. They are classics.

Only a hand full of these specimens were produced. Originally they were cuprite and have been mostly altered to malachite. If you look at the bottom of these specimens you can still see traces of cuprite. Then tiny quartz crystals covered the Malachite and in the sun light they sparkle like mad. The best one, to my knowledge is located in the Smithsonian institute.

At one point about 50 years ago when the Apex mine was operating some quantity of these specimens were produced, probably sever hundred. Today they are hardly ever seen, but some specimens of intergrown "sticks" more than 20 cm were collected and sold to collectors. One even appeared on the cover of Rocks and Minerals magazine.

Here are pictures crystals of Inyoite altering to little prismatic crystals of Meyerhofferite. In some cases the alteration is further along than others. These specimens are stable, at least in terms of not altering further in our lifetimes. These specimens were found recently, in the last ten years and their estimated stability is based on observations made on similar pseudomorphs found in Death Valley California that have been stable over the last 40 years. Certainly the Inyoite specimens from this locality are by far the finest in the world.

There is/was a tiny little mine/prospect in the Mt Blanco area just of 20 mule team canyon that produced the best examples of these pseudomorphs. The tunnel only went in 50 feet or so, but in one of the little drifts off the main tunnel, a small area produces at least two outstanding pockets of these specimens. Some few hundred specimens of this material were produced. Some of the specimens still showed vestiges or the original Inyoite. The material from the bottom of the pocket tended to be coated with little micro prismatic crystals of Meyerhofferite which made them more sparkling than those from the top which tended to be be chalky white, but sharper than the crystals from the bottom of the pocket. More than 40 years out of the ground in the polluted air of Los Angles, indicates that these specimens are stable and show no signs of falling apart.
