A complete, slightly oriented individual from the Mauritanian Sahara

NWA 18501 is an LL6 ordinary chondrite recovered as a complete, slightly oriented individual. This specimen weighs 6183 grams and carries fusion crust across roughly 65 percent of its surface, with well defined regmaglypts and contraction cracks formed during atmospheric entry. A single cut window marks where the classification sample was taken. It is the recorded main mass of the meteorite, held and offered by IMCA member Brian McDonald (IMCA #3323).

Structure and surface features

The crusted face shows the gentle doming and directional sculpting of a stone that held a stable attitude during part of its descent, together with thumbprint regmaglypts and shrinkage cracks that formed as the fresh crust cooled. About 65 percent of the exterior retains primary fusion crust, while the reverse carries the brown desert patina of its time on the ground, and one small sawn face exposes the interior where the type sample was removed. Internally the stone is a brecciated LL6, a recrystallized granoblastic matrix of olivine and low calcium pyroxene in which the original chondrules are largely absorbed, consistent with petrologic type 6 thermal metamorphism. Metal and troilite occur at the low abundance characteristic of the LL group. The petrographic report records a shock stage of S3 and a weathering grade of W2.

Discovery and provenance

The meteorite was found in 2025 at Gleib en Ndour, Mauritania, and purchased that year from a meteorite dealer in Morocco. Classification was carried out by J. Garcia, ADARA, with the type specimen of 20.29 grams deposited at the Museo de la Naturaleza y Arqueologia (MUNA) in Tenerife and a thin section held at ADARA. The entry was approved on 27 March 2026 under laboratory work number BMD 029.

Scientific context

LL ordinary chondrites carry low total iron and low metallic iron, the trait that defines the group. The type 6 designation reflects a high degree of parent body heating that equilibrated the minerals and erased most chondrule boundaries. Among classified stony meteorites, NWA 18501 is the only approved meteorite from Gleib en Ndour, Mauritania.

Frequently asked questions

What type of meteorite is NWA 18501?
It is an LL6 ordinary chondrite with a brecciated texture, a desert find from Mauritania.

How much of the surface has fusion crust?
Approximately 65 percent of the surface retains primary fusion crust.

Is it oriented?
It is slightly oriented, showing gentle doming and directional sculpting from a stable attitude during part of its flight.

Has the stone been cut?
A small sample was removed for classification, leaving one cut window. The piece is otherwise a complete individual and the recorded main mass.

Is it officially classified?
Yes. It is an official Meteoritical Bulletin entry (MB 115), classified by J. Garcia, ADARA.

Collector significance

Complete individuals that keep most of their fusion crust and show orientation features are valued as display pieces because they present the meteorite close to how it fell. As the recorded main mass of NWA 18501, this stone accounts for the bulk of the recovered material from this find. As a Premium Specimen, this stone qualifies for our white-glove delivery service, a fully insured, personal handoff arranged directly with the buyer at an approved domestic or international location. The full classification is published in the Meteoritical Bulletin entry for NWA 18501.

Finally, a non-toxic chapstick!
So I typically make my own products at home using beef tallow. But I was in dire need of chapstick, and just didn't have any time or energy to do it, so I came across this brand on Amazon and had to try. I love it! Not only is it HUGE, but it is unscented, it's glides on perfectly and my lips feel super moisturized for hours. As with all tallow products, you have to be super careful about letting this stuff sit in the heat. So if you were planning on keeping it in your purse or car, it'll definitely turn into a ooey gooey mess. I keep mine in my nightstand in an air-conditioned room, and even then it gets a bit too warm on our hot 103F Summer days. Nevertheless, I recommend to those who are looking for a non-toxic chapstick that super moisturizing.

Tried the wife’s stuff, and it’s a better tool for the job.
Husband review: The wife ordered this stuff for herself, skeptical about what’s in a lot of cosmetics. I always went straight for good ol’ Carmex; but I tried it once because I was too lazy to dig around for mine. This stuff is sometimes a better tool for the job. I service swimming pools and work outside in the sun, so I sometimes struggle with dehydration & get cracked lips occasionally. I put this on before bed, and it lasts all night so I wake up better off. It’s not medicated (what she wanted), but it’s hydrating. So while I still occasionally use Carmex at work, reapplying a few times to get damaged cracks together, I use this to maintain & finish the job overnight where the other stuff would have just evaporated within an hour. Another thing: it’s soft, where chap stick would pull on a sore/crack, this stuff goes on an into damaged places like a lubricant.

Very moisturizing but no honey flavor and can get greasy
The product is very moisturizing, that's for sure. Tube is large which makes for a messy application on a warm day. Was fine when temp dropped to 77 as shown in picture. Better to dab on with your finger regardless imo. No honey scent or flavor whatsoever which is greatly disappointing. I checked multiple times that I didn't accidently order a plain one. Had a faint meaty scent which is barely noticeable (I'm okay with that knowing it's all natural versus something with chemicals) but then it shouldn't be called "honey glazed". Would have been 5 stars if i wasnt misled and it was advertised as plain (or indicated that you don't taste the honey but it's there to neutralize the tallow flavor), also it could use some (more) beeswax to make it more stable. Suggest re-marketing it in a round tin as an all around balm and making a smaller tube with more beeswax for a lip balm. Versus a traditional lip balm, would recommend this product if you are okay with the nuances noted above.

What changed in the formula?? Now a chemical smell. 😕
What changed?? I got one in the fall and LOVED it more than any lip balm ever! But I just got two more (one for my car and one for my bag) and it has a strong chemical smell. I’ve used it for a week, hoping the smell would fade somehow, but it hasn’t. I would love an answer from the company about what changed. And please change back to the original formula! It was lovely, smooth with a slight sweet taste from the honey. The first one was 5 stars, and now I would say 2 at most, so I tried to average it at 4 stars (with hope for a change).

Warning!!! Contaminated!!!!
This is the second time I've ordered this lip balm. The first time, the lip balm was great, unscented and worked well, so well that i ordered another to keep in the car. I ordered the same one, just 3 ingredients - tallow, beeswax, and honey. Except this one is contaminated with some kind of chemicals! It leaves an awful taste that permeates my whole mouth. It's like chemicals or strong perfume and kind of stings! Not only am i disappointed but I'm furious because my child used it first! We still have the awful taste in our mouths and I'm concerned what kind of chemicals we might have just been exposed to.
