From Google Search using AI This stone shown in the picture is a type of rare stony meteorite, specifically an olivine Martian meteorite (Shergottite). Type: Olivine Martian stony meteorite (Shergottite). Origin: These igneous rocks formed in the crust of Mars. Features: They are characterized by their relatively young age compared to other meteorites, and in the picture, they appear dark olive in color due to their olivine mineral content. Note: These meteorites usually lack a clear fusion crust if found some time after their fall. This stone is a meteorite, and the picture shows it to be of the type containing olivine crystals embedded in a mineral matrix. Weight/Volume: The digital scale shows a reading of 108.3 (ml or grams depending on the device settings). Appearance: The stone is characterized by a green color and a distinct crystalline appearance. Origin: The origin of this type of meteorite is usually from the boundary region between the core and mantle of asteroids. Based on the characteristics of the stone shown in the picture and visual comparison with meteorite databases, this piece is likely a Diogenite meteorite. Properties and Information Type: Diogenite, a rare type of stony meteorite believed to have originated from the deep crust of the asteroid Vesta (4 Vesta). Visual Appearance: The stone features a coarse texture and clear grains of magnesium-rich pyroxene, which give it this speckled appearance in shades of olive green and black. Weight: The scale in the picture shows that the weight of this piece is 108.3 grams. Scientific Importance: These meteorites are considered samples from differentiated planetary bodies, helping scientists understand the crustal composition of large asteroids.
