An oxidized CV3 carbonaceous chondrite with a visible calcium-aluminum-rich inclusion

NWA 18497 is an oxidized CV3 carbonaceous chondrite, one of the most chemically primitive classes of stony meteorite. The cut face carries the texture that defines the CV group: abundant rounded chondrules set in a dark, olivine-rich matrix, together with a pale calcium-aluminum-rich inclusion, the kind of object that ranks among the oldest dated solids in the solar system. This specimen is a 15.64 gram end cut, with one face cut and polished to open the interior and the natural exterior retained on the reverse.

The meteorite was classified by J. Garcia at ADARA in the Canary Islands and is listed in the Meteoritical Bulletin as NWA 18497, CVox3, with a total known mass of 725 grams. Its workname during classification was BMD 038.

Structure and features

The polished face shows the two parts of the CV texture clearly. Well-defined chondrules, averaging close to 1.2 millimeters across and reaching larger sizes, sit packed within a dark, fine-grained matrix built mainly from micrometer-scale olivine and opaque phases. The chondrules run through shades of copper, orange, and tan, the result of low-level oxidation of dispersed metal and sulfides, while the matrix holds the dark gray to black background of the stone. Most chondrules carry porphyritic textures, with crystals of olivine and pyroxene set in finer material.

A pale, irregular calcium-aluminum-rich inclusion (CAI) is visible on the cut face. CAIs are refractory clumps that condensed from the early solar nebula before the chondrules formed, and the largest one recorded in the studied section of this meteorite measures about 9 millimeters. Amoeboid olivine aggregates, another early-formed component, are also present in the matrix. Fine fractures and thin light veins cross the surface, a record of the time the stone spent in the desert. As an end cut, the piece keeps one fully prepared face for viewing while the reverse holds its weathered natural crust.

Discovery and provenance

NWA 18497 was purchased in 2024 from an Algerian dealer and carries the regional Northwest Africa designation used for material recovered across the Sahara. It was classified by J. Garcia at ADARA, Petrography and Curation of Astromaterials, in the Canary Islands, Spain, and submitted by Jose Garcia. The classification is published in the Meteoritical Bulletin, no. 115. The type specimen is held at the Museo de la Naturaleza y Arqueologia (MUNA) in Tenerife, a thin section is retained at ADARA, and the main mass is recorded to Brian McDonald. The Meteoritical Bulletin lists the meteorite as a find with a low weathering grade.

Scientific context

CV chondrites are a group of carbonaceous chondrites known for large chondrules, a substantial dark matrix, and a high abundance of calcium-aluminum-rich inclusions. The best known member of the group is Allende, which fell in Mexico in 1969 and became one of the most studied meteorites in science. The group is divided into oxidized and reduced subgroups, and NWA 18497 belongs to the oxidized branch, recorded as CVox and assigned to the oxidized subgroup following the metal and sulfide chemistry described by Gattacceca and colleagues in 2020.

The petrographic type 3 records a primitive state in which the chondrules and matrix have seen little thermal change since they formed, so the original mineral chemistry survives. In NWA 18497 the chondrule population is dominated by FeO-poor Type I chondrules, with iron-rich Type II chondrules present only in small numbers. Olivine in the chondrules averages Fa8.6, the matrix olivine is far more iron-rich, and the dispersed metal carries a nickel content near 66 weight percent. Together these features place the stone in the CV3 group and give it a weak magnetic response. For background on how these stones are studied and named, see what is a chondrite and how meteorites are classified.

Frequently asked questions

What is a CV3 carbonaceous chondrite?
It is a primitive stony meteorite from the CV group, defined by large chondrules, a dark olivine-rich matrix, and abundant calcium-aluminum-rich inclusions. The 3 marks a low petrographic type, meaning the material has changed little since it formed in the early solar system.

What is the pale inclusion on the cut face?
It is a calcium-aluminum-rich inclusion, or CAI. CAIs are refractory solids that condensed from the early solar nebula and rank among the oldest dated materials in the solar system at about 4.567 billion years.

Is this specimen magnetic?
It contains dispersed metal and sulfides, so it shows a weak response to a magnet. It is far less magnetic than an iron meteorite or a metal-rich chondrite.

How should the end cut be stored and handled?
Handle it with clean hands or gloves and keep it in a dry place. As a desert find that contains some metal, low humidity helps protect the polished face and limits any further rust.

Why this matters to a collection

A CV3 oxidized chondrite puts several of the oldest objects in the solar system into a single specimen: chondrules that formed as molten droplets, a matrix of fine early dust, and calcium-aluminum-rich inclusions that predate the planets. An end cut shows both a full polished face and the natural exterior of the stone, and a visible CAI makes the connection to the early solar system easy to point out. 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.

The series as a whole so far 5/25
Format: Kindle
I read reviews before going into this book and I don't agree with one of the more harsh ones on the main trigger she had. It is stated clearly in the forward and it wasn't as blase as it was made out to be. It definitely is touched on more and hasn't just been brushed off as the series goes I definitely would recommend reading it. It's a good series just be for-warned I like the series as a whole. The characters are awesome I adore the fmc shes cute and adorable but also a badass. Though there are a bunch of holes for her that I feel like just got left out. The guys are interesting and shout out to yall for not making Gage a dragon. I'm tired of the broody ones who don't wanna talk aboit what they are being Dragons. Ki is my favorite You can definitely tell if is written by 2 different people though because the phrasing just doesn't match up and wouldn't be something people that age says. And it flip flops between them. I feel like there's substance without substance. We are 4 books in and we don't really know much back story on literally anyone more than right under surface deep. There are definitely favorite MMCs which is kind of disappointing since some get shoved to the wayside. Specifically both of the best friends. They're basically useless and it's made obvious as the books go on. As well as all the men are ungodly self deprecating. I enjoy the plot line for the most part like I said I enjoy the series its different and refreshing. I do feel like the series is being dragged out though unfortunately. And the latest cliff hanger was just meh. So hopefully the next book is the last one.

Wow!
Format: Kindle
This book was awesome! Seraphina and her family have moved to a new town. Her family is a bit... odd. She grew up learning how to protect herself from people who might hurt her. Bloodshed is a daily occurrence with her brothers and parents during their practice sessions, and it’s all fun and games unless you need to hide a body. Sera’s family is very close, and she’s been homeschooled most of her life. But in this new town she is going to start regular school as a senior at the local high school. Unfortunately, things at her school aren’t all they seem to be. Or perhaps more than they seem to be. Sera has her own demons to deal with, and she’s terrified her new friends will learn about her weird family and other issues and drop her like a rock. It turns out they have their own secrets as well. This story ends on a bit of a cliffhanger and I can’t wait to read the next one! This book is well written and well edited. The heroine is spunky and has a great heart and wicked sense of humor.

Great start
Format: Kindle
I loved this book! It's funny but still deals with tough themes, like chronic illness, a serial killer on the loose, and a dash of self-harm. The guys are interesting and distinct, we don't know too much about them yet. It does end on a really terrible cliffhanger but on the bright side the next book is out and I believe the series is complete. I have enjoyed both of these authors separately and this is a great team up!

Fudge!
Format: Kindle
Titles aren’t my strong suit. Sorry not sorry. That ending has me completely frustrated book two isn’t out yet. Just throwing that out there. First thing first, this is a high school book where the lead is under 18. Yea yea she’s about month from being an adult, but I can’t say I would’ve even opened the file if I’d realized. It’s not a smut fest or anything, but there is sexual tension as each party figures out their emotions. That being said, it’s a good book. There are some troubling parts, like how the supes come into their powers at 13, but most of those are dealt with in a way that makes sense. Kian is the exception. His whole arc pisses me off, especially since no one stepped in. Reflecting back on real world situations, ten or so years ago, I can see it happening, but it still makes me sick. Which, I’m sure was the whole damn point. For the most part, Courting Darkness is a fun read. I found myself laughing along with most of the set up. By the time it started getting serious, I’d grown to like the characters enough it held an impact. I’ll be adding book two to my list for when it comes out.

Intriguing
Format: Kindle
An intriguing story that played out slowly while introducing some unique characters. The story became quite fascinating to read as these same characters provided startling revelations to their lives. As their relationships evolve, more drama and mystery is revealed adding to my fascination. I can’t wait to read more.
