HAH 280 has a fine-grained matrix rich in silicates and shows dark chondrules. He is the second-most massive of the CK (Karoonda-like) carbonaceous chondrites and a very rare type of meteorite and is a slightly equilibrated carbonaceous chondrite with a total known weight of only 26.5 kg. CAI's are quite common and contain An-rich plagioclase and Ca-rich pyroxene. They contain a high proportion of carbon (up to 3%) which is in the form of graphite, carbonates and organic compounds, including amino acids. Radiometric dating of the meteorite itself suggests an age of about 4.5 billion years, suggesting it was formed at the very beginning of the Solar System, and which makes it among the oldest material known to exist. Hammadah al Hamra 280 a rare, unique Meteorite.
