NWA 18448, a freshly classified brecciated eucrite from Algeria

This 34.20g full slice is cut from the 900g main mass of NWA 18448, a brecciated eucrite (HED achondrite) recovered from the Saharan region of Algeria and purchased in 2024. The specimen was scientifically classified by Jose Garcia at ADARA Petrography & Curation of Astromaterials in the Canary Islands and approved by the Meteoritical Society Nomenclature Committee on 10 March 2026, with publication scheduled for Meteoritical Bulletin 115. Brian McDonald (IMCA #3323) holds the main mass and authored the working designation BMD 036 during the classification process.

Structure and features

The polished face of this 34.20g full slice exposes a well-developed brecciated fabric and, notably, several distinct FeNi metal flecks across the cut surface. The largest is a circular metal-rimmed inclusion that catches direct light and creates a focal point on the slice, with smaller reflective grains scattered through the matrix. Visible metal of this prominence in hand specimen is uncommon for eucrites, where the metal phase is typically minor and finely disseminated; here the accessory metal identified in ADARA's analysis is conspicuous enough to study under direct lighting. The fine-grained clastic matrix carries a diverse clast population that includes dark gray to nearly black pyroxene-rich clasts, cream to yellow-tan feldspathic clasts, and composite mottled fragments. Clast sizes range from sub-millimeter grains up to several millimeters across the cut surface. Hairline fractures with light-colored mineral infill cross portions of the slice, reflecting the low weathering grade noted in the official classification. A portion of the original exterior is preserved along one edge, retaining a reddish-brown weathering surface. The ADARA petrography confirmed the constituent minerals as Ca-rich pyroxene, low-Ca pyroxene, plagioclase, and a silica polymorph, with accessory chromite, troilite, and FeNi metal. Mineral chemistry: low-Ca pyroxene Fs60.8±0.6Wo1.7±0.2 (FeO/MnO 28 to 30), Ca-pyroxene Fs25.7±0.3Wo44.4±0.3 (FeO/MnO 27 to 31), and plagioclase An83.4±1.3. The specimen carries a moderate shock stage and a magnetic susceptibility of 3.78 (log χ).

Discovery and provenance

The 900g single stone was recovered from Algeria and entered the meteorite trade in 2024 through a dealer in Africa. Brian McDonald acquired the main mass and submitted the material to Jose Garcia at ADARA Petrography & Curation of Astromaterials (Calle Dr. Joaquín Artiles, 36, AP 3. Agüimes, 35260, Las Palmas, Canary Islands, Spain) for petrographic and geochemical analysis. The 20.88g type specimen is deposited at the Museo de la Naturaleza y Arqueología (MUNA) in Santa Cruz de Tenerife, Spain. The Meteoritical Society approved the official name Northwest Africa 18448 on 10 March 2026, with the full writeup scheduled for Meteoritical Bulletin 115.

Scientific context

Eucrites are basaltic igneous rocks that crystallized in the upper crust of a differentiated asteroid parent body. Spectroscopic and isotopic evidence links the HED achondrite clan (howardites, eucrites, and diogenites) to asteroid 4 Vesta, the second-largest body in the main asteroid belt. Brecciated eucrites such as NWA 18448 preserve a record of impact processing on that parent body: an original basaltic lithology was fragmented by surface impacts, then lithified into a coherent rock by subsequent shock and burial. The mineral chemistry reported by ADARA falls within established compositional ranges for eucritic basalts, and the clastic matrix with mineral and lithic clasts is consistent with surface-derived regolith or fragmental breccia formation on the parent body. As of the Meteoritical Society's most recent count, NWA 18448 is 1 of 273 approved brecciated eucrites.

Frequently asked questions

What is a brecciated eucrite? A brecciated eucrite is a basaltic meteorite from a differentiated asteroid whose original igneous fabric was fragmented by impacts on the parent body and then re-cemented into a coherent rock. NWA 18448 displays this clast-in-matrix texture throughout the slice.

Where did NWA 18448 come from? The 900g single stone was found in Algeria and purchased in 2024 from a meteorite dealer in Africa. The HED parent body is widely accepted to be asteroid 4 Vesta in the main belt.

Who performed the classification? The petrographic and geochemical analysis was performed by Jose Garcia at ADARA Petrography & Curation of Astromaterials in the Canary Islands, Spain. The 20.88g type specimen is deposited at the Museo de la Naturaleza y Arqueología (MUNA) in Santa Cruz de Tenerife.

Is this specimen officially recognized? Yes. NWA 18448 was approved by the Meteoritical Society Nomenclature Committee on 10 March 2026 and is published in Meteoritical Bulletin 115. The full entry is searchable in the Meteoritical Bulletin Database.

What does "full slice" mean? A full slice is a complete cross-sectional cut taken from one face of the parent stone through to the other, exposing the entire interior fabric in a single continuous plane. It differs from an end cut or a partial slice, both of which preserve less of the cross section.

Collector significance

HED achondrites occupy a central position in serious meteorite collections because they sample the crust of an identified asteroid parent body. A full slice of a recently classified brecciated eucrite gives the collector both a study-grade specimen and a documented entry in the published Meteoritical Bulletin record. The visible accessory metal phase on the polished face gives this specimen unusual visual character for an eucrite and lends itself well to display under direct lighting. The 34.20g weight places NWA 18448 in a display-friendly range suited to both private collections and educational reference. Every specimen ships with IMCA #3323 dealer documentation. The full classification entry for NWA 18448, including geochemistry, petrography, and type specimen deposition, is available at the Meteoritical Bulletin Database (code 86559).

Extremely durable, dogs love them
Color: 2 PC-Beef-Red, Color: 2 PC-Beef-Red
I was looking for the toughest and most durable dog chew bone I could find and this is it. I have bought multiple other brands that claim to be very durable and tough for a very long time and this is the one for sure. The shower has described this phone accurately and it truly does last. I purchased this bone about 2 months ago. As you see from the photos attached, this is a very well made chew bone and my aggressive pitbulls can't tear it apart do they try. They never get tired of it and chewing it every single day for hours on and keeping them very occupied. I have two bones and three pitbulls that chew on it every day. It is so adorable and has an awesome flavor to it which I think entices them even more to want to chew on it. The durability and Lasting power is amazing to me with these tough chewers. I highly recommend this product to everyone out there. I will say only one negative and that is that the middle wraparound piece they were able to pull off but that is not a big deal because there is plenty of bone which was under that cover in the middle of the bone. There's a few mauled chips missing from the ends but the life of this bone is obviously going to be a long time which really surprised me. Give it a shot if you have heavy duty chewers and you will find how awesome this phone really is and it's durability and strength our second to none in my opinion.

My dog loves it.
Color: 1 PC-Beef-Red
My dog is a super aggressive chewer when it comes to toys. Anything that is soft he rips apart. This one has a wonderful squeaky sound that makes him happy and he enjoys the smell of it. This is a very strong material and definitely worth the price.

Durable!

Alright, here's a product review for those Tough Dog Toys: Finally, a Toy That Survives My Monster! - Tough Dog Toys Review As the owner of a determined (and I mean determined) large breed chewer, finding toys that last longer than five minutes has been a constant and often frustrating quest. I've gone through countless plush toys ripped to shreds, rubber toys with chunks missing, and even some "indestructible" toys that met their demise far too quickly. That's why I was both hopeful and skeptical when I came across the Tough Dog Toys, designed specifically for aggressive chewers and large breeds. Let me tell you, these bone-shaped nylon toys are living up to their name. My power-chewing Labrador has been going at this thing for days now, and I'm genuinely impressed. Where other toys have succumbed to his relentless gnawing, the Tough Dog Toy has held its own. There are some minor teeth marks, as expected, but absolutely no significant damage, no pieces torn off, and no signs of imminent destruction. "Almost indestructible" might actually be an understatement! The design is simple but effective. The solid nylon construction feels incredibly durable, and the bone shape is easy for my dog to grip and maneuver. It's also a good size for a large breed – substantial enough that he can really get a good chew going without it disappearing in his mouth. What I appreciate most is the peace of mind this toy provides. I no longer have to constantly supervise playtime, fearing that he'll ingest pieces of a destroyed toy. This feels like a safe and long-lasting option for even the most enthusiastic chewers. Pros: * Truly durable – stands up to aggressive chewing from a large breed. * Solid nylon construction feels virtually indestructible. * Safe design with no small parts to break off. * Good size and shape for large dogs to grip and enjoy. * Provides long-lasting entertainment. Cons: * May show some teeth marks over time (though this hasn't compromised its integrity). * It's a fairly hard material, so dogs who prefer softer toys might not be as interested. Overall: If you're at your wit's end trying to find a toy that can withstand your aggressive chewing large breed dog, I highly recommend giving the Tough Dog Toys a try. This bone toy has proven to be the most durable option we've encountered, offering excellent value for money and, most importantly, a safe and engaging chewing experience for your furry friend. Five out of five paws!

Very well made chew bone!
Color: 1 PC-Beef-Red
Great durable, very well made chew bone! Our dog usually tears up all his toys within a few minutes or sometimes hours after he gets them. He’s had this bone for a few days and it’s still in one piece. Except for the rubber that’s in the middle, he chewed up in a couple of days. I would definitely buy more chew toys made by this company! Well worth the money!

The rubber middle is not durable, it lasted less than 3 hours.
Color: 1 PC-Beef-Red
I bought this as I have bully/husky puppies (9 months old) and a pitt/doberman (9 years old). They are heavy chewers and destroy everything. I saw a video of this toy. The woman said that her dog chewed on it for a while (about 2 hours or so) she showed the ends visibly chewed, which I expect but it was holding up. The rubber middle seemed to hold up to. I received this yesterday. I had to take it away from them last night as they were chewing the rubber middle off. They had it maybe 3 hours. I didn't give it a lower star score as I will just cut the rubber off and give it back to them. So I was disappointed in the rubber middle not being more durable but the hard plastic it's made from is the strong material they need.
