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).

Japanese-Style 4-Panel Screen Room Divider: Beautiful, But...
Color: Black, Color: Black
I really like this product, and would gladly recommend it. But there are a few things you want to know before buy: Likes 👍👍👍 - Looks great! See photos I shared. - Works as advertised: divides your space and provides privacy, with elegance and style. - Lightweight: It is super light and easy to move around. Dislikes 👎👎👎 - Flimsy: according to the dictionary, that means "light and easily damaged" 🧐 - Pricey: Anything is worth what you're willing to pay for it! But I think this should be $75 tops! - Shaky: You need to position it just right, or it could tip over really easily. I had to reposition mine because it almost got blown by a floor fan! True story 😅 - Print is on one side only which will bother some of you. I'm a recovering OCD 😂 My Verdict 🧐 - Despite its shortcomings, I like this thing, and I would buy it again! 😅 It has character and really adds to your space. So, now that you know what you're getting, you can make up your own mind! I've already bought mine 😉 Happy shopping 😊 Hope my review has helped you make a more informed buying decision 👍😊👋

Cute backdrop for videos and room separation
Color: Black
Bought this because sometimes you need emotional boundaries AND physical ones. Surprisingly sturdy, looks nice on camera, and makes a room feel more peaceful instantly. Side note I have 2 cats and 2 large dogs and it has took a couple of beatings but did not damage at all!

Transforming Space: A Tale of Two Stunning Room Dividers
Color: Black, Color: Black
The four-panel screen room divider is absolutely stunning! Unfortunately, the first one the FedEx driver delivered ended up at the wrong address. After notifying Amazon, they promptly sent me a “replacement” room divider through UPS, which arrived right on schedule. Now, I find myself with two beautiful dividers! They both enhance the aesthetic of my home. I informed Amazon that my first room divider magically appeared today in my building’s lobby. I’ve placed one of the new screen dividers in front of an old one, and the modern Roundhill divider really makes my older piece look outdated! The Roundhill screen divider is sleek, bold, and refreshing—I’m in love with it. The second divider serves a practical purpose by hiding my bulky grocery cart, fan, and vacuum cleaner. These items used to clutter my living room closet, making it difficult to access due to the abundance of coats I had stuffed in there. Now, all those items are neatly tucked away behind the elegant Roundhill four-panel screen divider, bringing a sense of order to my space. Thanks, Amazon! ♥️ Thanks, Roundhill! ♥️

Beautiful, Sturdy, Well Made, good Value for the money
Color: Black
I don’t know what the bad reviews are about. This is a beautiful, well made 4 panel screen. The screen print appears to be a standard print that is likely the same on every screen they produce (not hand painted by two different people). It is beautiful. Everything about it, including the colors and the screen print image on rice paper, is more lovely than the photos. The wooden frame (black) is solid and sturdy. The hinges are stable and well positioned. When people say lightweight it sounds misleading. It is lightweight enough to easily maneuver but this four panel screen is sturdy and stable. It is slim and tall so someone could conceivably bump into it and jostle it. But no more so than any number of other items in one’s home. I highly recommend this beautiful, lovely, fine piece of home decor. I purchased this as a divider between my work station (office) and my living room. Also, even though there was a slight dent in the package when it was delivered, it wasn’t a deep enough gash to damage the screen. When I pulled the screen from the box my first thought was just how study it is. So very pleased with this purchase.
