📸Meteorite Recon (Oum Dreyga).

Spent way too long just admiring this one. Those green-gold crystals are olivine (gem-quality peridot) suspended in nickel-iron, formed at the core-mantle boundary of a shattered asteroid ~4.5 billion years ago. Wild that you can hold a cross-section of a dead planet's interior.

Backlit, they glow like stained glass. Anyone else completely obsessed with pallasites? Which locality is your favorite — Seymchan, Brenham, or Sericho?

That is meteorite "Chelyabinsk" at a field. It was found 2015 year.

P.s. I learn English, i decided write and read the Reddit) I think meteorites that interesting.

On 27 August 2026, thieves took most of the Bronze Age gold from the Museum of Villena in Spain, in about four minutes. Two iron pieces from the hoard were not taken: a bracelet (about 32 g) and a small cap covered in gold.

A 2023 paper in Trabajos de Prehistoria (Rovira-Llorens, Renzi & Montero-Ruiz, open access, CC BY) argues both are very probably meteoritic iron. The interesting part is the nickel: the bracelet's first sample (a flake of surface rust taken in 2007, measured in 2010) came back at 2.8% Ni, which was read as "too little nickel to be meteoritic iron". A 2013 resample a little deeper, under the rust, gave 5.33% Ni. The corrosion layer had been losing nickel. Ni/Fe and Ni/Co ratios then plotted with iron meteorites, and both pieces carry more than 400 ppm germanium.

I made a video that goes through the theft timeline and the analysis, if anyone wants the long version: https://youtu.be/SFH7zXhmv-Q

Happy to be corrected on any of the geochemistry.

Been admiring this etched Muonionalusta piece — the crisscross lattice is just unreal when you think it took millions of years to form as the nickel-iron cooled in space. Still blows my mind that you can't fake this on Earth.

What's everyone's favorite iron meteorite for that classic pattern — Muonionalusta, Gibeon, or something rarer?

I liked where it looks like it was almost cut in two.

pallasite meteorite

My dad just passed away and I inherited this meteorite piece. Do I need to do anything to protect it from rust (or anything else?). It was just displayed in his living room, but I live in a much more humid climate than he did. Any suggestions appreciated.

76 years on planet Earth.
Zambia’s first witnessed fall meteorite.
Classified as L6 OC.
This specimen is a broken-off fragment of a larger piece from Dipper Co. meteorites— IMCA 8120.

I didn’t think to post this on Reddit. But, pew pew meteor! What makes it green?

Well, I’ve found my long-lost slice of (probably?) Seymchan, and I’m afraid it looks as if it’s been in the bottom of a box for 25 years or so in accidental and un-climate-controlled storage in coastal Florida.

This is probably because it’s been in the bottom of a box for 25 years or so in accidental and un-climate-controlled storage in coastal Florida.

I want to send it off for whatever the heck can be done for it. Anyone here up for the challenge? If no, does anyone know of such a service?

Okay, thanks for your time. I hope everyone is doing well.

And, wow, does it ever look rough.

A beautiful Lunar meteorite, classified as a Troctolitic Anorthosite.

A group of falconers discovered this fall while looking for birds along the Egyptian-Libyan border. A fairly large recovery by lunar meteorite standards, with some pieces showing some really neat inclusions when sliced!

My little Nantan nugget

Organized my meteorite and fossil collection.

I'm not entirely sure which meteorite it is. Genuine watches use Gibeon, but I'm reasonably certain the replicas don't. Muonionalusta would be the obvious choice, but it's possible they could be using Aletai slices without inclusions, or something else cheap and available? Does this look like a Muonionalusta to anyone?

Did anyone else see something in the sky over Surrey tonight around 7:45 PM?

I saw what looked like a bright green ball with a tail moving toward the south. It was visible for maybe 2–3 seconds and then disappeared.
It looked like a meteor/fireball to me, but I’m wondering if anyone else saw it or captured a video. Anyone know what it was?

Denader 002:

Classification: Ungrouped achondrite

Found: 2024, near Gao, Mali

Total known weight: approximately 514 grams

Weathering/Shock: Moderate weathering, high shock stage

Denader 002 is a rare albite-rich achondrite recovered in Mali in 2024. This meteorite exhibits a texture of green pyroxene and olivine crystals set in pale albite feldspar, accompanied by scattered chromite and iron metal grains — a mineral assemblage consistent with a differentiated, once-molten crustal rock rather than a primitive chondrite. It is currently classified simply as "ungrouped achondrite," meaning it doesn't fit cleanly into any of the established achondrite groups (HED, angrite, aubrite, etc.).

The scientifically interesting part of Denader 002's story isn't really the stone in isolation — it's the company it keeps. Over the past several years, meteoriticists have identified a small but growing cluster of ungrouped, plagioclase-dominated achondrites that share an unusual bulk chemistry: feldspar contents in the 60–80 vol% range (sometimes nearly pure albite or anorthite end-members), roughly 20% ortho- or clinopyroxene, and accessory silica polymorphs, phosphate, chromite, troilite, and FeNi metal. A recent survey of this group explicitly lists Denader 002 alongside Erg Atouila 001, Erg Chech 002, GRA 06128/06129, Nema 001, and several Northwest Africa specimens (NWA 6698/16789, 15820, 11575, 11119) as members of this emerging class.

It's worth being precise about terminology here: these are not "paired" meteorites in the strict sense (fragments of one fall, split by atmospheric breakup or recovered as separate stones from the same strewn field). They were found in different places and years — Denader 002 in Mali (2024), Erg Atouila 001 and Erg Chech 002 in the Algeria/Mali Sahara region, Al Bir Lahlou 001 in Western Sahara (2021). Rather, they're grouped scientifically because they appear to represent a related family of silica-rich, feldspathic crustal rocks — possibly sampling similar kinds of early differentiated parent bodies, even if not the same one.

Just wondering if this would be potential real meteorite and and is it worth it?

I know nothing about meteorites and how to tell its authenticity.

Any potential guidance would be appreciated.
