 Andorite
A stack of thin tabular andorite crystals comprise this thumbnail from the San Jose Mine in Oruro, Bolivia. Andorite is a lead silver antimony sulfide and is named after the Hungarian patron Andor von Semsey. Because he gave vast financial assistance to the Mineral Collection of the Hungarian National Museum, Professor Joseph Krenner named andorite and semseyite after him as a mark of his great respect.

 Boléite
This intergrown crystal pair of boléite (a lead copper silver oxychloride) comes from the Amelia Mine in the type locality of Boléo, Santa Rosalía, Baja California Sur, Mexico. I apologize for the poor photo, boléite crystals are typically so small (this one's 3 mm on edge) that I just can't photograph it properly. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen! | |
|
 Boléite
Once in a great while, a matrix specimen of boléite appears - this thumbnail's also from the Amelia Mine. Thanks to Alexander Falster's auction on eBay for the specimen! | | |

 Boléite and
Penfieldite This miniature of boléite and penfieldite, a very rare lead hydroxychloride, (larger image, right) on matrix is from the mid-2001 find at Sierra Gorda, Caracoles District, Antofagasta, Chile. Also, recent microprobe analyses of boléite have found that there's 0.36% potassium in its composition - the link under the image here reflects the change. Thanks to John Veevaert at Trinity Minerals for the specimen! |
|
| Row 6 |
|---|
 Boléite and
Penfieldite
Another boleite / penfieldite miniature - this on;es from the Margarita Mine, Sierra Gorda, near Antofagasta, Chile; my earlier specimen may be from the same locale. Thanks to Anthony Jones' auction on eBay for the specimen! |

|---|
 Boulangerite
A small plastic box of intergrown boulangerite needles from somewhere in Mexico. Ex: James F. Carryer collection. |
|
 Bournonite
Bournonite (lead copper antimony sulfide) is often called "cogwheel ore" because of its multiply-twinned radiating crystals. In England it's called endellionite from Endellion in Cornwall (its type locality). This miniature (with manganocalcite and quartz) comes from the Pachapaqui Mine in Bolognesi Province, Ancash, Peru. Bournonite is sometimes used as an ore of lead (42.5%), copper, or antimony. It forms a complete series with seligmannite, where arsenic replaces the antimony, and an incomplete series with soucekite where bismuth replaces the antimony and selenium replaces some of the sulfur. There's often a small amount of tin present as well. Thanks to Rick Green at Uniquely Crystalline for the specimen and the image! | |
|

|
 Cechite
When iron and manganese substitute for the zinc in descloizite (or the copper in mottramite) it becomes cechite - it's very rare and only occurs in tiny black crystals (one's ENE of the arrow), as in this hematite and calcite micromount from the type locality of Vrancice, Pribram, Bohemia, Czech Republic. Thanks to Tony Nikischer at the Excalibur Mineral Company for the specimen! | |
|
 Cerussite
Cerussite (lead carbonate) is an important lead ore. The crystals, like calcite, are doubly refracting. The fluorescence of the cerussites is interesting - it's a bright yellow but seems to be in either the center or bottom of each crystal rather than uniformly distributed! This one, with its accompanying orange barites and resting on a massive galena layer backed by limonite, comes from Mibladen, Morocco. Thanks to Rick Green at Uniquely Crystalline for the specimen and the image! | |
|
| Row 10 |

 Linarite
An old (Denver Mineral Show, 10 Sep 1978) miniature with big radial sprays of linarite - you don't see crystals like these very often! It's also from the Blanchard Claims (there's the typical galena, anglesite, fluorite association) and has an Earth Gems & Minerals (Turlock, California) tag. Thanks to Leigh DelRay's auction on eBay for the specimen and the images! | |

 Liveingite
A small cabinet specimen of liveingite (a lead arsenic sulfide) with realgar in matrix from the type locality of the Lengenbach Quarry, Binntal, Switzerland. It has a Ward's tag (which says "Rathite", but it also has a Robert E. Jenkins, II tag, who reanalyzed it). Thanks to C. Carter Rich's table at the 2004 Carnegie Gem & Mineral Show for the specimen! | |

 Maricopaite
This thumbnail of white radiating sprays of maricopaite (closeup), a lead calcium zeolite, and yellow mimetite comes from its type locality - Moon Anchor Mine, Tonopah, Maricopa County, Arizona. Thanks to Richard Dale's auction on eBay for the specimen and the image! | |

 Mendipite
A miniature of light-pink mendipite, lead oxychloride, (larger image, top right) in white hydrocerussite with micro green pyromorphite (larger image, bottom left) - the label has a confusing locality, either the Higher Pitts Mine (type locality) or the Merehead Quarry, Mendip Hills, Somereset, England. Thanks to auction on eBay for the specimen and the image! | |

 Meneghinite
Meneghinite's a rare lead copper antimony sulfide - this miniature comes from the Kalkan Quarry, Santa Cruz County, California. Most of the literature shows the copper content. It's a member of the aikinite group. |
|
 Mimetite
A miniature of mimetite (lead chloroarsenate) with a little bit of reasonably transparent wulfenite on limonite from Mapimi in Durango, Mexico. There's one colorless crystal of something (probably dolomite) riding on top. The mimetite fluoresces brownish-orange. The wulfenite habit here is atypical; it's almost equant cubes (closeup). Mimetite is dimorphous with clinomimetite. Thanks to Dave Hayward at Lucky Strike Minerals for the specimen and the image! |

 Mimetite
This beautiful miniature of bright (neon) orange mimetite on limonite is from the Rowley Mine outside of Theba, Maricopa County, Arizona. It's also got a couple of clear (so transparent, they're almost invisible - see closeup) yellow wulfenite crystals, and on the back, some barite blades. Thanks to Olympic Mountain Gems, Inc. for the specimen and the image! | |

 Mimetite
This extremely gemmy mimetite miniature is from the mid-2000 find in Hat Yai, Songkla, Thailand - I'm not sure what the matrix is (probably botryoidal goethite). Philipsbornite, a lead aluminum hydroarsenate, was also associated with mimetite from there. Thanks to Jeff & Gloria's table at the 2000 Carnegie Gem & Mineral Show for the specimen! | |

A small cabinet specimen of mimetite clusters on barite flowers from the San Francisco Mine in Sonora, Mexico. Thanks to Brian McManus's (Pebble Peddler) auction on eBay for the specimen and the image! |

 Mimetite,
var. Bellite
Bellite, or chromian mimetite, occurs here as red-orange to yellow (depending on the amount of chromium present) hexagonal microcrystals on matrix along with boléite (larger image, middle row, center), galena (larger image, middle row, right) and an unidentified dark green mineral (larger image, middle row, left). It's named after W. R. Bell, the Tasmanian prospector who first discovered this very rare mineral (in Tasmania) in 1910. This small cabinet piece is from the 2003 find in the Ponderosa Mine in Sierra Gorda, Antofagasta, Chile. It may, according to Tom Loomis of Dakota Matrix Minerals, become a mineral in its own right someday. Thanks to the House of Onyx for the specimen! |

 Mimetite, var.
Campylite
When mimetite occurs in orange botryoidal masses, it's called campylite - this beautiful miniature (it's much brighter than it appears here) is from San Pedro Corralitos, Chihuahua, Mexico. Thanks to Tom Klinepeter's auction on eBay for the specimen and the image! | |
