Kamacite is documented to contain significant trace element components.Įtch depth in sample references (a) NWA 13876 and (b) NWA 7160, after 60 min of etching with 0.1 mol dm −3 iodine as oxidizing agent. The Campo del Cielo sample for example is an iron-nickel meteorite entirely composed of iron-nickel rich mineral phases. They showed the capacity to classify chondrules of H3 chondrites petrographically into six widely disperse chondrules. The silicate matrix is made of chondrule forming olivine and pyroxene, with traces of plagioclase feldspar. Near Earth asteroids contain valuable platinum group metals and iron, nickel, and cobalt greater than that found on the Earth's surface.ĭiverse samples of chondrites contained iron-nickel alloys, iron sulfide and iron oxide minerals, while less abundant in iron-nickel-rich minerals with a higher proportion of iron sulfide. ![]() ![]() These metals can provide a local source of materials to establish a human settlement in space or other terrestrial bodies. These large metal-rich asteroids are parental bodies of iron meteorites and metal-rich carbonaceous chondrites. It is possible to establish viable extraterrestrial metal extractions, and the efficient use of local materials and resource recovery from space can significantly reduce the mass, cost, and environmental constraints of space missions. The scientists subjected the samples to chemical micro-etching experiments with iodine and iron (III) chloride as oxidizing agents in a deep eutectic solvent formed by mixing choline chloride and ethylene glycol. ![]() The chondrite samples contained silicates with metal-rich phases such as native alloys, sulfides, and oxides, of which, the metallic iron-nickel and troilite formed the most abundant metal-bearing phases in all three samples, with specific hues in the iron-rich meteorite. The team studied three types of meteorites, two chondrites, and one iron meteorite.
