For #MeteoriteMonday, I present this fresh example of the Oum Dreyga meteorite.

On October 16, 2003, Moroccan soldiers witnessed a fireball over the Western Sahara. They recovered #meteorites from the fall, which were analyzed and classified as H3-5 chondrites.

Example shown weighs 11 grams and is from the Galactic Stone & Ironworks Collection. Not for sale.

For #MeteoriteMonday and #MineralMonday, I present the NWA 11273 #meteorite.

NWA 11273 is a lunar feldspathic breccia that was blasted off the surface of the #Moon by an ancient asteroid impact.

The ejected material then fell to Earth as #meteorites. Nomads in the Algerian Sahara recovered the meteorites, which were then analyzed by scientists at the University of Washington.

For #ThinSectionThursday, I present the NWA 4723 meteorite.

NWA 4723 is the official Meteoritical Bulletin catalog name for a single large L3 chondrite stone recovered from the Saharan Desert in Morocco prior to 2006.

Photo shows a close-up of a single chondrule-like structure. It's unusual appearance resembles a face of some kind. What do you see?

For #MeteoriteMonday, this is the #Imilac pallasite.

Imilac #meteorites were first recovered out of Chile's Atacama Desert in 1822. It is a #pallasite type of meteorite that represents the core/mantle boundary of a large asteroid.

Specimen shown is a polished slice from the Galactic Stone & Ironworks Collection. Not for sale.

For #MeteoriteMonday, I present the NWA 791 #meteorite.

NWA 791 is a L5 chondrite recovered out of the Moroccan Sahara in 2001.

The NASA Ames Vertical Gun research team used this meteorite as a test target for high speed projectiles to better understand the impact dynamics of asteroid-like materials.

This specimen is a 9-gram slice that resides in the Galactic Stone & Ironworks collection.

Some #meteorite history for #MeteoriteMonday

In 1942, the legendary Harvey Nininger founded the American Meteorite Museum on the old Route 66 in Arizona.

It was the first such museum open to the public with a hands-on educational approach to meteorite science. It was open from 1942 to 1960. The remnants of the museum now stand as a desolate ruin.

Nininger's work was ground-breaking and he is considered the grandfather of modern #meteoritics and meteorite hunting.

For #ThinSectionThursday, I present the NWA 4910 #meteorite, also known as the "Begaa" meteorite.

This meteorite was recovered from the Sahara near Begaa Morocco in 1999. It was analyzed and officially classified as a LL3.1 chondrite. It is rich in chondrules of all types.

What is it?

Or, I guess I should say What are they?

Clues : they are meteorite-related and extremely rare. Not only is the type of specimen very rare, but the material itself is quite rare.

So, to recap : a rare form of a rare type of meteorite-related material.

I will post the answer later this week after they arrive in the mail.

For #ThinSectionThursday I present the NWA 1950 Martian #meteorite.

The NWA 1950 meteorite was recovered from the Atlas mountains of Morocco in 2001. It was analyzed by French scientists and classified as a "lherzolitic shergottite" of Martian origin.

For #MeteoriteMonday and #MineralMonday, I present the Sericho meteorite.

Sericho is a type of stony-iron #meteorite known as a #pallasite. Sericho meteorites were first recovered near the village of Habaswein in Kenya in 2016.

Pallasites are composed of a nickel-iron matrix with scattered olivine (peridot) crystals, and they represent the core-mantle zone of a large asteroid.

This specimen has been sliced, stabilized, and made into a pendant.

For #MeteoriteMonday this is the La Criolla meteorite.

La Criolla fell near Concordia Argentina on Jan. 06, 1985. A brilliant fireball in the sky was followed by multiple detonations. Approx. 45kg of #meteorites were recovered. Analysis revealed them to be L6 chondrites.

This specimen has fresh black fusion crust and weighs 62 grams. It is about the size of a small lemon. From the Galactic Stone & Ironworks Collection (not for sale).

For #ThinSectionThursday I present the SAU 008 Martian #meteorite.

SAU 008 was recovered from the Sayh al Uhaymir area of the Al Wusta desert in Oman. It is a basaltic shergottite that originates from the planet #Mars.

Shergottites are an igneous rock composed mostly of olivine, plagioclase, and maskelynite.

For #ThinSectionThursday, this is the Faith #meteorite. Faith is a H5 chondrite that was recovered from a Perkins County South Dakota farm in 1952.

The photo (first image) shows a textbook barred olivine #chondrule. I was so enthralled with this perfect chondrule that I decided to paint it (second image).

For #ThinSectionThursday, this is the Los Angeles 001 Martian meteorite.

It is a #shergottite that was recovered in the 1970s by a rockhound in the Mojave Desert. It was not recognized as a #meteorite until 1999. Los Angeles 001 originates from the planet #Mars and is one of the only Martian meteorites recovered in the USA.
