Esquel Pallasite #1 – 14 g

913,18 $

Esquel is part of the pallasite group.

This meteorite was discovered in Argentina in Patagonia in 1951.

Esquel is certainly one of the most beautiful pallasites in the world and is not subject to oxidation like some other pallasites.

Pallasites are certainly the most aesthetic group of meteorites that we know.

A very nice acquisition for your collection !

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.
