oh apparently there is a #MeteoriteMonday here too, so here's my little buddy, a piece of nickel-iron that fell on Russia about a hundred years ago!

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 #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.

I've just discovered #MineralMonday and #MeteoriteMonday 😬

For #MeteoriteMonday and #MineralMonday, I present the Campo del Cielo iron #meteorite.

Campo del Cielo #meteorites originate from the Chaco province of Argentina. They have been known to indigenous peoples for centuries.

It was first analyzed by scientists in the 20th century and officially classified as a type IAB-MG, coarse octahedrite.

This fine example weighs approx. 11kg and is from the Galactic Stone & Ironworks collection. Not for sale.

For #MeteoriteMonday and #MineralMonday, I present these stony chondrites.

These are unclassified #météorites recovered from the Moroccan Sahara.

All of them have similar characteristics : wind polished rinds of desert varnish, little fusion crust remaining, and high iron content.

They are likely H-type chondrites of the H5 or H6 variety : highly equilibrated with few chondrules and prolific metal flecks in the matrix.

From the Galactic Stone & Ironworks Collection. Not for sale.

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 #MeteoriteMonday and #MineralMonday, this is the Sikhote Alin iron #meteorite.

On Feb 12th 1947, approx. 23 tons of iron #meteorites fell over the Sikhote Alin mountains in the far east of Russia. The brilliant fireball and deafening explosion was witnessed up to 200 miles away.

Sikhote Alin is a type IIAB coarse octahedrite.

The specimen shown here weighs 47 grams and is from the Galactic Stone & Ironworks Collection (not for sale)

For #MeteoriteMonday. This is a slice of Imilac pallasite meteorite.

#Pallasites are a stony-iron class of #meteorites that represent the mantle-core boundary zone of a large differentiated asteroid. They are composed of a mixture of nickel-iron matrix and olivine (peridot) crystals. Imilac pallasites are found in Chile's Atacama Desert.

This specimen is an 82g slice from the Galactic Stone & Ironworks Collection. Not for sale.
