One of only 13 IIE irons recognized

NWA 1929, Morocco

Found 2003

Achondrite, Howardite 14g

Howardites likely represent the regolith of the asteroid Vesta. These polymict breccias are thought to be formed by the mixing of eucrite crust with the upper mantle diogenite rocks by large impacts.

NWA 1955, Morocco

Found 2002

H/L3-4, 14g

This rare meteorite is currently the only one in the world classified as an H/L3-4. It is a breccia composed of fragments of both type 3 and type 4 material and the chemistry (iron content of the olivine and pyroxine, etc.), which usually gives a distinct grouping, was odd enough to not give a certain H or L typing to this strange specimen.

NWA 2388, Northwest Africa

The fresh fully crusted 81g mass was purchased from a Moroccan dealer in September 2004

Carbonaceous Chondrite CK6, 9.7g

This was only the second of eleven known CK6 specimens found.

NWA 2871, Northwest Africa

Found 2004/2005

Primitive achondrite, Lodranite, 4.6g

This was originally classified as an acapulcoite (and still is by the Meteoritical Bulletin Database). Both acapulcoites and lodranites come from the same parent body and are chemically and isotopically indistinguishable. Their only difference is in their average crystal grain size; acapulcoites less than 0.3mm and lodranites greater than 0.45mm. This stone has an average grain size of 0.6 to 0.7mm. The researchers who originally classified this rare stone mistakenly thought that the lodranite cutoff was 0.75mm when they submitted the original classification paper work on this meteorite.

NWA 516, Northwest Africa

Found 2000

Winonaite, 0.74g

This is 1 of only 20 approved meteorites classified as Winonaite.

NWA 725, Morocco

NWA 753, Sahara Desert near Kem Kem, Morocco

Found 2000

Rumuruti chondrite R3.9, 9.2g

This is one of only four approved meteorites classified as R3.9. Weathering grade is only W2 on this specimen making it one of the freshest R chondrites besides the type name Rumuruti.

NWA 800, Algeria/Morocco

Rumuruti chondrite R4, 6g

Total known weight 400g

This end piece is a beautiful example of an R-chondrite, clearly showing the typical breccia texture common to this type meteorite.

NWA 853, Er Rachidia, Morocco

Purchased March 6, 2001

Achondrite Ureilite, 6g

A single piece of 720g was found. Ureilites are composed of the pyroxene pigeonite and olivine in a carbon-rich matrix and are often shocked enough to contain diamonds. This specimen shows a carbon fiber-like refraction from the graphite under angled lighting.

Orgueil, France

Observed fall May 14, 1864

Carbonaceous Chondrite CI1, 1g

These very fragile and friable meteorites are the most primitive in terms of solar elemental composition, have the highest volatile hydrocarbons, and the highest content of water (17-22% of weight). They are chondrites that have no chondrules.

There are only nine CI1 specimens in existence, five falls including Orgueil, and four found in Antarctica.

Peña Blanca Spring, Marathon, Brewster County, Texas

Observed fall August 2, 1946

Aubrite, 138g

This stone meteorite fell directly into a spring, breaking into two pieces upon contact with the bottom of the pond. More than a dozen people witnessed the fall. This Aubrite is almost white, and very little metal is visible. The fusion crust is thin and cream-colored.

Discolored area lower left is from an old label.

Sahara Desert

EH3, 44g

This specimen was collected prior to the numbering of the Sahara EH3's.

St Genevieve County (extreme western part of county), Missouri

Found 1888

Medium octahedrite IIIF, 102g

This specimen is from the Oscar E. Monnig collection. St Genevieve County is one of only eight approved meteorites classified as IIIF.

Tambo Quemado, Leoncio, Ayuacucho, Peru

Found before 1950

Medium octahedrite, IIIB (IIIAB), 292g

When this meteorite was "discovered" by outsiders the locals demanded payment for its loss to them, which they received in the form of cement for their public school.

Tuxtuac, Zacatecas, Mexico

Observed fall October 16, 1975, but first fragments not located for several years.

Olivine-hypersthene Chondrite, Amphoterite LL5, 196g

Tuxtuac is an unusual LL group chondrite because it lacks veining and brecciation features. Metal iron occurs within the meteorite as small angular grains associated with troilite. Chondrules are clearly defined and come in several varieties with colors ranging from dark brown to tan.

This specimen has a fusion crust with regmaglypts, fractured surface discolored from the heat, and a beautiful polished surface.

Vaca Muerta, Taltal Dist., Chile

Found 1861

Mesosiderite-A1, 112g

Mesosiderites are thought to have formed when a silicate rich asteroid collided at high speed with a metal rich asteroid smashing together and mixing their content to form this unusual meteorite. Vaca Muerta is one of only six approved meteorites classified as Mesosiderite-A1.

This end piece shows the beautiful mixture of metal and stone.
