You are viewing meteorite Ksar Ghilane 022 which was found in Tatawin, Tunisia in 2023, and is classified as an ungrouped achondrite, magnesium-rich clinopyroxenite with sulphite spheres!
This is without a doubt one of the most exciting meteorites to recently surface for several reasons, but mainly because there will soon be a paper published suggesting a possible link to a parent body to which a meteorite has not been previously linked, which will truly go down in history! So, this big question is, "what parent body?"
Phobos, the larger of Mars' two moons, measures 17 x 14 x 11 miles and orbits the planet three times a day. Having survived a near-catastrophic impact, Phobos is marked by numerous gouges from countless meteorite collisions. However, it is on a slow collision course with Mars, moving closer at a rate of six feet every 100 years. In about 50 million years, Phobos will either crash into the Martian surface or disintegrate to form a ring system.
Ksar Ghilane 022 has scientists intrigued, as it is very consistent with Phobos. from relative reflectivity to hydrogen content and stable isotopic dating, it’s essentially a perfect match. With that being said, as of today there is no way to know for certain that this would be indeed from Phobos, but there is enough data to suggest that it indeed is.
The physical characteristics of this meteorite show a lack of fusion crust, exhibiting mottled dark and light gray granular surfaces. The interiors consist of equigranular aggregates of light gray and white grains.
The specimen predominantly comprises nearly pure augite, accompanied by minor enstatite and accessory minerals like Cr-troilite, daubreelite, alabandite, and an Mn-Fe oxide phase. Enstatite occurs as small irregular inclusions or thin lamellae within the augite grains, and the varying macroscopic colors of the augite reflect different concentrations of sulfide inclusions. Additionally, some secondary calcite veins are present.
