Montoume #5 – 128 g

17,83 $
An impactite is a terrestrial rock modified by the impact of a large meteorite.
These rocks contain an agglomeration of fallout dust and fragments.
The Rochechouart impactites were formed as a result of a meteorite impact about 207 million years ago in New Aquitaine in the Rochechouart district.
The impact crater of the Rochechouart meteorite is called “Astroblème” because it is no longer visible following erosion.
There are several types of rocks :
Les brèches de type Babaudus, riche en verre à texture fluidale et en vacuoles
The “breccias” of Montoume type, red because of their richness in iron, metal supposed to come from the asteroid.
The “breccias” of Chassenon type, debris of glass of greenish tint.
The “breccias” of Rochechouart type, contain little glass and are constituted of elements of varied size and lithology.

Lahmada 048 is an achondrite ureilite meteorite of only 59 grams discovered in the Western Sahara in a concentration area called Lahmada.

It was discovered on September 23, 2020 by Brahim Elguirah.

Lahmada 048 certainly contains diamonds in view of the difficulties to cut it.

The diamonds, which are rarely larger than a few micrometers in diameter, are probably the result of high-pressure shock waves produced by the collision of the parent body of the ureilites with other asteroids.

Allende CV3 #9 – 3,4 g

The Allende meteorite fell in Mexico in 1969.

It is often considered as the “Rosetta Stone” of planetologists, because it has improved our knowledge on the origins of our solar system. This meteorite was formed before our planet, in the very first moments of the solar system. It preserves in its heart the traces of the nebula which generated the Sun and its procession of planets.
