A substantial end cut of NWA 18497, an oxidized CV3 carbonaceous chondrite

NWA 18497 belongs to the CV group of carbonaceous chondrites, primitive stony meteorites that preserve solids from the earliest stage of the solar system. At 71.00 grams, this end cut carries a broad polished face crowded with chondrules in copper, orange, and tan tones set against a dark olivine-rich matrix, along with a pale gray inclusion of the type that ranks among the oldest dated objects known to science. The reverse keeps the natural weathered exterior, where chondrules stand out in relief across the surface of the stone.

The Meteoritical Bulletin lists NWA 18497 as CVox3 with a total known mass of 725 grams. It was classified by J. Garcia at ADARA in the Canary Islands and carried the workname BMD 038 during study.

Structure and features

The polished face reads like a map of the early solar nebula. Chondrules average close to 1.2 millimeters in the studied section and reach larger sizes, most showing porphyritic textures in which crystals of olivine and pyroxene sit within finer groundmass. FeO-poor Type I chondrules dominate the population. Between them runs the compact, fine-grained matrix, built from micrometer-scale olivine and opaque phases, which gives the cut face its dark background.

Near one margin of the face sits a pale gray inclusion with the irregular outline characteristic of calcium-aluminum-rich inclusions (CAIs), refractory objects that condensed before the chondrules formed. The classification work on this meteorite documents CAIs from submillimeter size up to almost a centimeter, including one measuring about 9 millimeters in the studied thin section, along with amoeboid olivine aggregates in the matrix. Thin light veins thread across the stone, a record of desert exposure. On the uncut surfaces, differential weathering has etched the matrix back and left individual chondrules standing proud, so the chondritic texture can be read on the natural exterior as well as the polished interior.

Discovery and provenance

The stone was purchased from an Algerian dealer in 2024 and carries the Northwest Africa designation applied to material recovered across the Sahara without precise find coordinates. Classification was performed by J. Garcia at ADARA, Petrography and Curation of Astromaterials, in the Canary Islands, Spain, with the submission made by Jose Garcia, and the entry is published in Meteoritical Bulletin no. 115. The type specimen rests at the Museo de la Naturaleza y Arqueologia (MUNA) in Tenerife, ADARA retains a thin section, and the main mass is recorded with Brian McDonald. The Bulletin records the meteorite as a find with a low weathering grade.

Scientific context

CV chondrites take their name from the Vigarano fall and are best known through Allende, the 1969 Mexican fall that became one of the most analyzed rocks in planetary science. The group is defined by large chondrules, an abundant dark matrix, and a high content of calcium-aluminum-rich inclusions. CV chondrites divide into reduced and oxidized branches, and NWA 18497 falls on the oxidized side, assigned following the metal and sulfide chemistry framework published by Gattacceca and colleagues in 2020.

The petrographic type 3 marks an unequilibrated stone whose minerals never reached a common composition through heating. In NWA 18497 that heterogeneity is strong: chondrule olivine averages Fa8.6 while matrix olivine runs near Fa50, and the sparse metal carries nickel near 66 weight percent. These values, together with the Type I dominated chondrule population and the presence of AOAs and CAIs, anchor the stone in the CV3 group.

Frequently asked questions

What does CVox3 mean?
CV identifies the group of carbonaceous chondrites, ox marks the oxidized subgroup based on metal and sulfide chemistry, and 3 is the petrographic type, indicating material that has changed little since it formed in the early solar system.

What is the pale gray patch on the polished face?
It has the form of a calcium-aluminum-rich inclusion, a refractory object that condensed from the solar nebula before the chondrules. CAIs are documented throughout this meteorite, including one about 9 millimeters across in the classified thin section.

How is an end cut different from a slice?
A slice is taken from the interior and polished on both faces, while an end cut preserves one polished face and keeps the natural exterior of the stone on the other side. This piece shows the interior texture and the weathered outer surface in a single specimen.

Will it respond to a magnet, and how should it be stored?
It gives only a weak pull, far less than an iron meteorite, since metal is sparse and partly oxidized. Handle it with clean hands or gloves and keep it in a dry environment to protect the polished face.

Collector significance

Few specimens compress as much early solar system history into one object as a CV3: chondrules that froze from molten droplets, fine dust that became matrix, and refractory inclusions older than the planets. At 71.00 grams, this end cut offers a broad polished face for display alongside the natural exterior of the stone. As of June 2026, the Meteoritical Bulletin lists this as 1 of 64 approved meteorites classified as CVox3. This specimen is offered by Treasure Coast Meteorite Co., IMCA Member #3323.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good

My new favorite shirts!
Fit Type: Regular Fit, Color: Grey, Size: Large
These are my new favorite shirts! I just ordered a 3rd. i wish there were more colors. Yes, the cotton is heavy-weight and I like that. They are just a bit warmer than regular dress shirts. The fit is excellent. I'm 5'9", 200lbs and L fits perfectly. Enough room without being blousy. The sleeves are long enough (finally!). (Most other 16.5/32-33 shirts always have sleeves that are too short). The fit/finish and detail is surprisingly good. They don't really shrink after washing and come out very soft. Not wrinkle-free, but that's ok since it means that the 100% cotton hasn't been dosed with chemicals. I expect they will wear very well over time.

Excellent value and has saved me from the sun!
Fit Type: Regular Fit, Color: White, Size: Large
I ordered this large mans shirt because it was 100% cotton and long sleeve. I am a woman and use it to protect myself from the sun walking my dog, very stiff at first, but comes out with several washes. I love the shirt!
