A valuable slice of a chondrite discovered in 2000, from the Sahara Desert in North Africa. The NWA 869 meteorite is a particularly recommended meteorite among stony meteorites. The NWA 869 meteorite is a stony meteorite discovered around 2000 in the Sahara Desert of Northwest Africa. Its characteristics are diverse, but what is particularly scientifically interesting is its origin and composition. Key Features: Classification: Classified as a chondrite (L3-6) stony meteorite. Chondrites are characterized by containing "chondrules," which are small, spherical particles formed when molten rock and metal rapidly cooled and solidified in the early solar system. Discovery Location: Large quantities have been found in Northwest Africa, particularly near the border of Morocco and Algeria in the Sahara Desert. The name "NWA" stands for "North West Africa." Composition: Primarily composed of rocks such as olivine and orthopyroxene. It also contains iron, giving it the property of being attracted to magnets. Origin: It is a regolith breccia, thought to have been formed by the collision and thermal bonding of fragments from multiple different meteorites. Therefore, it is characterized by the coexistence of different types of materials within a single stone. Scientifically, it is also called a "meteorite science classroom" because it contains such diverse information. History: The surface is often covered with a black, glassy layer called a "fusion crust," which is formed by the heat and friction of passing through the atmosphere when falling to Earth. The total amount discovered exceeds 2 tons, and it is estimated that it was scattered over a wide area by a large-scale meteorite shower.
