description Aioun el Atrouss Overview
Aioun el Atrouss is a meteorite classified as a diogenite that was observed falling in Mauritania in 1974. It is a coarse-grained orthopyroxenite, representing deep crustal igneous material from the HED parent body, which scientists have identified as the asteroid 4 Vesta. As an observed fall, it provides researchers with relatively unweathered specimens for studying the geological processes of differentiated asteroids. The meteorite is preserved in various institutional collections for ongoing planetary science research.
help Aioun el Atrouss FAQ
What type of meteorite is Aioun el Atrouss?
Aioun el Atrouss is classified as a diogenite, which is a coarse-grained orthopyroxenite. This means it is a type of achondrite meteorite composed of deep crustal igneous material.
Where and when did the Aioun el Atrouss meteorite fall?
The meteorite was observed falling in the nation of Mauritania in 1974. It is named after the specific locale where it was recovered.
Where does the Aioun el Atrouss meteorite originate from?
Scientists have identified the HED parent body as the asteroid 4 Vesta, which is one of the largest objects in the asteroid belt. This meteorite represents chunks of Vesta's deep crust that were blasted into space by impacts.
What is the scientific significance of diogenite meteorites like Aioun el Atrouss?
They provide rare, physical samples of deep crustal igneous material from a differentiated planetary body. Studying them helps scientists understand the volcanic processes that occurred on protoplanets early in the solar system's history.
