• DETAILED DESCRIPTION

The Al Haggounia 001 meteorite – enstatite chondrite from Western Sahara The Al Haggounia 001 meteorite was discovered in 2006 near Al Haggounia. It was initially classified as an aubrite (an enstatite-rich achondrite), but subsequent studies reclassified it as an incompletely melted and vesicular impact melt belonging to an EL-type enstatite chondrite. Mass and surface characteristics This meteorite is particularly known for its mass. Approximately 3 tonnes of material have been found scattered over an area of about 40 km. Fragments vary from a few grams to several tens of kilograms. The outer surface often appears rusty brown due to significant terrestrial alteration, a sign of long exposure to terrestrial environmental conditions. Composition and structure From a mineralogical perspective, Al Haggounia 001 is mainly composed of enstatite and plagioclase, with the presence of troilite, graphite, daubréelite, oldhamite, silicon-rich kamacite, and schreibersite. Its porous structure and the presence of yellow sulfur spots indicate extensive alteration.
