r/meteorites

I thought I could get away without stabilising this piece, but after some advice I'm going to give it a couple of weeks of electrolysis before I go any further

Classified as monomictic eucrite, don’t know why it’s like that in the photo, but the crust is so shiny in person, very glossy.

Daule is classified as L5 ordinary chondrite
Thuathe is classified as H3-4 ordinary chondrite
Lost City is classified as H5 ordinary chondrite

Left is an Indochinite from Vietnam, the one at the right is an Agni Manitite from Indonesia.

As what you can see, Agni Manitites share a bit of similarity with its fellow pseudotektite Saffordite from the US. They are commonly marketed and mistaken to be real tektites as they resemble one. My Agni Manitite resembles a Muong-Nong type of tektite if not backlit. Agni Manitites are volcanic glass, not impact related, in contrast to the real tektites, which are non-volcanic, but impact related.

This is the first meteorite I've added to my geology/mineralogy collection, although I've always been fascinated by them. Super excited about the clear Widmanstatten patterns. Tips on storing? Currently in a glass display cabinet.

Not sure where this one is from exactly but I welcome any guesses in the comments

What a privilege to write with these pens. They are such incredibly unique pieces!

Got a big slice of Aletai to make a replica Tutankhamun dagger.

Oued Sfayat : H5 Chondrite

Confirmed witnessed fall: May 16th, 2019

Location: Tindouf, Algeria (26°42.433’N, 6°9.766’W)

This piece is a great example of a late break up in ablative flight. Great flight shaped piece with outstanding rollover lipping and slight secondary crust. It may be a small piece, but it has a ton of character.

History of this fall: On May 16, 2019, a meteor was seen by a group of shepherds at 9:00 pm (local time) at the Dakhla camp in Tindouf, Algeria. The meteor came in at a low angle (about 30 °) from the west and was moving east at a relatively low velocity. A shockwave was felt as the meteor exploded, and a booming sound was heard near the camp. Hibballah, one of the shepherds present at the camp, went in search alone the following morning (May 17, 2019) for pieces of potential meteorites that may have fallen, by following the direction of the observed meteor trail and booming sound. That same day, Hibbballah recovered the first fragment, an 80 g freshly crusted individual in the area of Oued Sfayat, a river valley about 70 km to the east of the Dakhla camp. After finding this piece, Hibballah returned to the camp to tell his father Oueld Ennajm the location where he had found the first piece. Several days later, Oueld Ennajm and some shepherds traveled to Oued Sfayat and over the next few months went searching for more fragments. After searching between the end of May through the middle July in a 1-2 km area at Oued Sfayat, about 8 kg of freshly crusted individual fragments (mostly small stones of varying sizes between 10-60 g, with the exception of a few larger-sized individuals ~600 g) were recovered by Oueld Ennajm and the shepherds. Some of these recovered fragments were then later sold to Ahmed Chacha and Otman Sidi Ahmed. Later on, some of the purchased fragments (2.6 kg) were subsequently purchased by Youssef Bennani, who later sent some small stones in for analysis.

Of course who will forget about Murchison if we’re talking about historic mets? One of the most well-studied mets of all time. Aguas Zarcas is a much recent and therefore, pristine version of Murchison, fell in Costa Rica and hit homes and tore through the roof of a dog house! (Dog was ok)

Ivuna is the mother of all CI-type chondrites like Orgueil, Alais and Tonk, many more. Rare class and historic as well. Fell in Tanzania, 1938.

Vigarano on the other hand is the mother of all CV-type chondrites like Allende, some NWA and Dar al Gani mets. Italian meteorite, fell 1910, rare and historic like Ivuna.

Tagish Lake and Tarda are within a rare class of carbonaceous chondrites being ungrouped with an aqueous alteration at 2. They are extremely porous, sensitive to terrestrial weathering and crumbly.

A few years ago I got obsessed with one question: what's the oldest material a human can actually hold?
The answer is meteorite. Specifically Muonionalusta — formed 4.5 billion years ago. Before Earth existed. Before the Sun had planets.

When you cut and etch it with acid, something incredible appears — a pattern called Widmanstätten. It's a crystal structure that forms when iron and nickel cool at a rate of 1 degree per million years. You literally cannot fake it. No factory can replicate it. Each pattern is completely unique, like a fingerprint left by deep space.

I've been cutting this material and making it into rings, bracelets and pendants. Every time I etch a new piece and the pattern appears for the first time, it still stops me cold.

Here are some close-up shots of the pattern on recent pieces.

Happy to answer any questions about the material, the science, or the process.

334 grams! Butter my butt and call me a biscuit, it's beautiful. 😍

Anybody know if Amazon Prime now does Meteor delivery in phoenix?

Yeah yeah keep making fun of my intoxicated 1am grammar. N 51st Ave and US-10 is the direction and I'm S 39th Ave and Baseline.

So we are talking approximately a bearing of 322" or NorthWest to be specific from my vantage point. Star formation triangulation and trajectory calculation pinpointed the scatter field somewhere 8 Miles outside of Wickenburg, AZ.

It’s just under the size of a dinner plate. What a pain to take pictures of, it wants to reflect everything. I kind of like these iron only sections of pallasites. It’s like they don’t really belong 🤣
The other ones I really like are Gyarub Zangbo iron sections.

Just something magical about NWA 869.

Such beginner friendly specimens with a wide lithology. Actually is my first piece in my collection.

Could you identify if this is a meteorite?
Found in Japan.
