A0U-PARAlbite-Anorthite Series, Fayalite-Forsterite Series

Morocco

Dimensions: 10 mm x 8 mm x 4 mm
Weight: 0.48 g

NWA 8687 lunar troctolite meteorite was discovered in 2014 and classified by C. Agee at UNM in 2014 as a monomict breccia composed mainly of light plagioclase and green olivine. End cut with polished cut face to show interior, which shows shock melt veins.

KUX-G07CI1 chondrite meteorite, Magnesite, Graphite

Orgueil meteorite, Orgueil, Tarn-et-Garonne, Occitanie, France

Dimensions: 3 mm x 2 mm x 2 mm
Weight: 40 mg

Small specimen of the Orgueil meteorite. Observed fall on 14 May 1864. Example of a primitive CI1 carbonaceous chondrite. These are fragile specimens which are composed of material from the original solar nebula. The white crystals are likely hydrated sulfates that formed after exposure to the moisture in the atmosphere, but probably help to cement the fragile porous primitive material together.

HKH-FKYL6 chondrite meteorite

L'Aigle meteorite, L'Aigle, Orne, Normandy, France

Dimensions: 28 mm x 17 mm x 3 mm
Weight: 3.48 g

Slice of L'Aigle meteorite. L6 ordinary chondrite which fell on April 26, 1803. Jean-Baptiste Biot from the French Academy of Sciences published a detailed study of the meteorite which established extraterrestrial origin for the first time. Scattered flecks of meteoritic iron are seen throughout the chondritic specimen.

T7F-T9QMeteoritic Iron

Alsace, France

Dimensions: 24 mm x 15 mm x 3 mm
Weight: 2.47 g

Slice of Ensisheim meteorite. Historically important LL6 ordinary chondrite, fall observed on November 7, 1492. This is the oldest meteorite for which specific date of the fall is known. Contains internal flecks of meteoritic iron.

CHC-GPVMeteoritic Iron

Sikhote-Alin meteorite, Paseka village, Primorsky Krai, Russia

Dimensions: 72 mm x 37 mm x 20 mm

130.1 gram specimen of Sikhote-Alin meteorite with nicely demonstrated regmaglypts, which are depressions caused by areas of metal ablation during extreme heating during atmospheric entry.

Black Beauty Meteorite

Morocco

11x10x6 mm, 0.82 grams. This is the end cut side of this Martian basaltic breccia, showing the shiny fusion crust. The cut side is shown in another photo uploaded. This was found in the strewn field of NWA 7034 and has been visually confirmed by Dr. Carl Agee at UNM and Dr. Laurence Garvie at ASU. I have also uploaded a photo of a slice of NWA 7034 separately.

Black Beauty Meteorite

Morocco

0.82 grams, 11x10x6mm. This is a specimen matching the NWA 7034 main mass, which is a unique Martian basaltic breccia. This fragment was found in the same strewn field and has been visually matched by Dr. Carl Agee at UNM and Dr. Laurence Garvie at ASU. This small specimen contain a characteristic "blueberry" (iron-oxide concretion specific to these meteorites), in addition to lighter clasts. I have also uploaded a photo of a slice of NWA 7034 separately.

0Q6-A9CMartian (basaltic breccia) meteorite

Multiple photos available
Northwest Africa 7034 Martian meteorite, Northwest Africa Meteorites

Dimensions: 70 mm x 80 mm x 7 mm
Weight: 19.21 g

I was fortunate enough, thanks Dr. Laurence Garvie (of the ASU Center for Meteorite Studies), to be given the opportunity to photograph this ASU collection specimen of the "Black Beauty" Martian basaltic breccia meteorite. This specimen is a slice from the main mass characterized by Dr. Carl Agee at UNM*. Some characteristics of the meteorite one can see here are dark rounded iron oxide spherical concretions (called "blueberries"), lighter colored igneous clasts, and gray teardrop shaped impact melts.

Morocco

Dimensions: 63 mm x 56 mm x 26 mm
Weight: 142 g

L type chondrite from a large strewn field in Northwest Africa, found in 2000. This is a half stone, and I have uploaded a back side view to shown the crust, as well as a view with lighting to highlight the metal flecks throughout the meteorite.
