NWA 17472 is one of 358 approved Martian shergottites in the world. This 65.00g full slice presents the complete cross-section of an evolved basaltic shergottite, with maskelynite accounting for approximately 40% of the visible surface and clinopyroxene grains showing the core-to-rim zoning that records igneous crystallization on Mars. The shock stage is published as high.

The specimen

This 65.00g full slice preserves the complete internal cross-section of the parent stone, maximizing viewable surface area without reducing the specimen to smaller cuts. Bright, reflective maskelynite zones contrast sharply with the darker pyroxene matrix across the full face of the slice, giving the piece immediate visual identification as shocked Martian material without magnification. Clinopyroxene grains averaging 300 to 500 microns are distributed throughout, with complex core-to-rim zoning visible under magnification: Mg-rich pigeonite cores mantled by augite and rimmed with ferropigeonite, recording the full igneous crystallization sequence from the Martian crust.

The two parent stones, 1.8 kg and 1.2 kg, were found together with weathered fusion crust. At 65.00g, this full slice is a substantial display-scale piece of that inventory, sized for presentation rather than micro-mount or reference collecting.

Classification and scientific context

NWA 17472 is classified in the Meteoritical Bulletin (MB 114, approved March 27, 2025) as Martian (Shergottite), purchased in Northwest Africa in 2024. Classification was performed by C. Agee at the Institute of Meteoritics, University of New Mexico. The type specimen, 20.9g, is held at UNM. MetBull fieldname CB-5.

The evolved basaltic shergottite designation places NWA 17472 in a well-documented group of Martian meteorites with pyroxene compositions comparable to QUE 94201, NWA 12335, NWA 12522, NWA 12908, NWA 12960, NWA 15910, NWA 16127, Ben Kesbes 002, and Socorro. Shergottites preserve basaltic textures formed in the Martian crust, providing direct samples of the planet's igneous history. To understand how Martian meteorites are identified and classified, see our Learn section.

The maskelynite present in this slice is diagnostic of the hypervelocity impact that launched this rock off the surface of Mars. Plagioclase feldspar subjected to shock pressures exceeding 30 GPa is converted to amorphous glass while retaining its original composition and grain morphology. Maskelynite grains here are thin and elongate with maximum lengths of approximately 1 mm, representing roughly 40% modal abundance. Clinopyroxene accounts for approximately 50% modal abundance. Published shock stage is high. Weathering grade is moderate. Minor phases include merrillite, titanomagnetite, ilmenite, and troilite.

Published geochemistry by electron microprobe (UNM): clinopyroxene Fs40.8±18.9Wo22.3±10.5 (Fe/Mn=34±4, n=10); plagioclase An55.8±5.1Ab43.4±4.8 (n=8). Martian origin is confirmed through oxygen isotope ratios distinct from Earth and Moon, trapped atmospheric gases matching in-situ measurements from Viking and Curiosity, and mineral chemistry consistent with Martian crustal rocks as established by spacecraft data.

Frequently asked questions

Is NWA 17472 officially classified?
Yes. NWA 17472 is approved in the Meteoritical Bulletin, MB 114 (approved March 27, 2025), as Martian (Shergottite), purchased in Northwest Africa in 2024. Classification was conducted by C. Agee at the Institute of Meteoritics, University of New Mexico.

What is maskelynite and why does it matter?
Maskelynite is plagioclase feldspar transformed into glass by shock pressures exceeding 30 GPa, without melting. Because only hypervelocity impact can generate these pressures, maskelynite is a diagnostic signature of the ejection event that launched the rock off Mars. It appears here as bright, reflective zones accounting for approximately 40% of the slice surface, with elongate grains up to 1 mm in length.

What does "evolved basaltic shergottite" mean?
Evolved refers to the degree of igneous differentiation recorded in the pyroxene chemistry. NWA 17472 shows clinopyroxene compositions comparable to a well-documented group of evolved shergottites including QUE 94201 and NWA 12335, indicating crystallization from a magma that had undergone significant iron enrichment relative to more primitive shergottites. Basaltic refers to the fine-grained igneous texture, as distinct from olivine-phyric or lherzolitic shergottite types.

How is Martian origin confirmed?
Through oxygen isotope ratios distinct from Earth and Moon, trapped atmospheric gases matching in-situ measurements by Viking and Curiosity, and mineral chemistry consistent with Martian crustal rocks established by spacecraft data. Shergottites match compositional data collected from the Martian surface by multiple missions.

Why choose a full slice over an end cut or partial slice?
A full slice captures the complete internal cross-section, maximizing viewable surface area for shock features and igneous texture. It provides superior display quality relative to partial slices while preserving more of the specimen's internal record than an end cut.

What documentation is included?
A certificate of authenticity from Treasure Coast Meteorite Co. (IMCA #3323) documenting classification and provenance, referencing the Meteoritical Bulletin entry for NWA 17472, MB 114.

Unbelievable toy for aggressive chewers
Color: Green Cactus
Great toy for aggressive chewers! I'm not one to hand out 5 star reviews but this one I 100% believe in. I bought the first one in 2023 and just replaced it because it broke. Now this is not a played with every once in a while, this was played with daily as it is his favorite toy. Very few toys last long but this one has went beyond my expectations. Could not be happier.

Not Recommended!
Color: Green Cactus
Be aware that with major chewers it is not durable. My dog tour right through it and was eating pieces off of it. Thankfully we got the pieces back out of his mouth but definitely not for tough chewers. Also only lasted 2 days in decent condition and was only used on the occasion throughout the day.

Not strong lasting
Color: Green Cactus
Didn’t even last 3 hours in my house. Too rubbery and our frenchie mix was able to bite pieces off and was trying to eat them. Don’t recommend as a super chewer or consider it durable

Very durable!
Color: Pink Cactus
One of the few actually tough chew toys for dogs who tear apart toys in seconds! My dog loves this thing and has yet to break into the rubber!

Withstands big dog
Color: Green Cactus
As a dog mom to two active pups, I’ve gone through a LOT of chew toys over the years and honestly, many of them just didn’t hold up. Some cracked, broke apart quickly, or became rough after only a short time of chewing. That’s why I was genuinely impressed with the MewaJump chew toy. Both of my dogs immediately loved it, and what stood out most to me was how durable it’s been compared to other toys we’ve tried. It’s held up really well with aggressive chewing while still seeming safe and comfortable for them to use. I also love that it keeps them entertained and engaged longer without constantly worrying about pieces breaking off. Definitely one of the better dog toys we’ve added to our home lately and Molly and Piper would agree.
