PGA-QVEWulfenite

Mystery Mine, Gleeson, Turquoise Mining District, Dragoon Mts, Cochise Co., Arizona, USA

Dimensions: 5 cm x 3 cm x 2.5 cm

"Wulfenite loves... unusual localities"

Unusual locality for this wulfenite, which was self-collected by faculty member of Virginia Tech Museum of Geosciences, Dr. Bob Bodnar. He tells here the story of its discovery.
"I collected the wulfenite sample in January 1977 at the Mystery Silver Bill Mine near Gleeson Arizona. Back then, I was a graduate student in geology at the University of Arizona. My grad student colleagues and I were also mineral collectors (Will Wilkinson, Frances Sousa, Ty Schuiling, and others) and we would regularly go to the old abandoned silver-lead-zinc-copper mines in southern Arizona to collect minerals. We usually would arrive at the mines at around sunset and go underground and collect all night, leaving before dawn because entering the mines was “discouraged", although many mineral collectors did enter to collect specimens. The wulfenite is from one of our many visits to the MSB."

A62-9V6Wulfenite

Mežica Mines, Mežica, Carinthia Region, Slovenia

Dimensions: 8 cm x 6.5 cm x 4 cm

"Wulfenite loves... twisted localities!"

This wulfenite specimen was labeled in the Strasbourg Mineralogy Museum's collection to be from the historic Bleiberg deposit in Austria, mined for lead (and zinc) from the 16th century until the late 1980's. However, and thanks to the Mindat Community and further research in our collection, it looks like this specimen most likely comes from Mezica instead! We found another specimen in the Museum looking a lot like this one, and labeled Mezica (Slovenia). This deposit is also known for lead and zinc mining (for 350 years!), therefore the possible mistakes of mislabeling.

It was the first mineral bought by Paul Groth, the founder of the Mineral Institute of Strasbourg, on the 4th of April 1872, and is in the collection since then (Musée de Minéralogie de Strasbourg, France). It was acquired for 4 Kronen from Seifert at Teplice in the Czech Republic. The mistake of labeling could have been original when the wulfenite was purchased, or could have been introduced later.

34N-U4GCassedanneite

Berezovsk Deposit, Beryozovsky, Sverdlovsk Oblast, Russia

Field of View: 2.5 mm

"Wulfenite loves... cassedanneite"
This specimen comes from Jacques Cassedanne's collection (1928-2018), and is now in the collection of the "Musée national d'histoire naturelle" of Luxembourg (MnhnL).
Cassedanneite was dedicated to Jacques due to his great work on the Pb-Zn Brazilian deposits.
It is not a lead molybdate like wulfenite but a lead chromate vanadate. Cassedanneite and wulfenite have the same orange - red color.

HR8-29PWulfenite, Quartz

Lauchentyre Mine, Gatehouse of Fleet, Dumfries and Galloway, Scotland, UK

Field of View: 5 mm

"Wulfenite loves... Scotland!"

A single, bright yellow, bladed/tabular crystal (2 – 3mm) of wulfenite showing good crystal forms in a small cavity in a quartz vein from an old copper mine at Lauchentyre (spelled “Lackentyre” in some documents), 6.5 km (4 miles) west of Gatehouse-of-Fleet, Kirkcudbrightshire. Recorded originally by Matthew Forster Heddle in a short paper in 1866, the mineral was found in material collected at the then recently opened Lauchentyre Mine and presented to Heddle by a Mr James Russell. In his 1866 paper, Heddle notes that a single specimen (then simply called a molybdate of lead) in the Stockholm Academy labelled as coming from Churchill in Somerset, England had already been examined by the great Swedish chemist Jakob Berzelius (1779 –1848). If this information is correct, then the Lauchentyre location is the second UK occurrence and the first for Scotland. However, J. G Goodchild states in a letter to the Geological Magazine in 1875 that wulfenite “has hitherto been recorded from only one locality in the British Isles, viz. Lackentyre (sic.) in Kirkcudbrightshire”, which may mean that the Lauchentyre / Lackentyre locality is the first UK occurrence. The mine itself proved to be unproductive and had already closed down prior to publication of the paper. Very little evidence of the mine can now be found on the ground today so the possibility of recovering more material is extremely remote. It may well be that the specimens in the collection of the National Museums Scotland are the only ones in existence from this important British locality. Since then other specimens of wulfenite have come to light from other Scottish localities though none have surpassed the Lauchentyre material. This specimen is from the Patrick Dudgeon Collection, in the National Museums Scotland.

H4D-FNHWulfenite, Baryte, Pyromorphite, Fluorite

Lantignié, Beaujeu, Rhône, Auvergne-Rhône-Alpes, France

Field of View: 55 mm
Largest Crystal Size: 12 mm

This image is a detail of a larger specimen (24 x 18 x 6 cm) showing 3 orange-brownish wulfenite crystals ranging from 7 up to 12 mm wide. Wulfenite crystals grow as secondary mineralization together with platy green pyromorphite and transparent fluorite cubes on orange baryte. Originally, the Lantigné deposit was mined mainly for massive fluorite and baryte. Centimetric wulfenite crystals from this area are not common and this sample is quite a good representation to show that "Wulfenite loves ... France too"!
This specimen was acquired thanks to Total-foundation credits, for the collection of the Muséum National d'Histoire Naturelle (France).

WTT-GXFWulfenite, Mimetite

Cerro Prieto, Cucurpe, Cucurpe Municipality, Sonora, Mexico

Dimensions: 6 cm x 5 cm x 5 cm

"Wulfenite loves... mimetite"

This aesthetic specimen of bright yellow-orange wulfenite covered partially with balls of orange mimetite is typical of the Cerro Prieto locality (Sonora, Mexico). It was added to the collection of the Musée des Confluences (Lyon, France) thanks to a donation by Alexis Chermette, who was a French geologist and specialist of fluorite.

LD8-16WWulfenite, Cerussite

Jianshan Mine, Ruoqiang Co., Bayin'gholin Autonomous Prefecture, Xinjiang, China

Dimensions: 20 cm x 10 cm x 10 cm

"Wulfenite loves... cerussite"

China entered the small circle of countries producing the best wulfenites at the end of the 20th century. It quickly found its place thanks to the beautiful crystals from the Jianshan Mine (Ruoquiang Co., Bayin'gholin Autonomous Prefecture, Xinjiang). They are bright orange to red, sometimes reaching 4 cm in length. Around 2010, this deposit was singled out by a discovery, small in number of specimens but important by its quality: flat crystals of orange wulfenite covered by cerussite, except for their edges. The contrast and the aesthetic are striking. This specimen from the Sorbonne University collection is the largest known to date.

G2V-9G2Wulfenite, Calcite

Multiple photos available
Ojuela Mine, Mapimí, Mapimí Municipality, Durango, Mexico

Dimensions: 24 cm x 11.5 cm x 8.5 cm
Field of View: 4 cm
Largest Crystal Size: 1.5 cm

"Wulfenite loves... calcite"

This specimen is composed of centimetric yellow wulfenite crystals partially covered with brownish-pink calcite, on top of a goethitic matrix. It was most likely acquired in 1969 or 1970 by the School of Mines and has been in the collection since, under the catalog number 15760.
This photo is a close-up on one wulfenite crystal (1.5 cm across) topped up with colored calcite crystals, giving this specimen an unusual touch, more typical of old timers than recent Ojuela Mine wulfenite specimens.
