It is a chondritic type,^[4] but the samples showed unusual radionuclide profiles when analyzed in 1962: the Michigan State University sample was unusually high in potassium (higher than any other chondrite), rubidium (higher than any other meteorite), and caesium, while the Smithsonian Institution sample uniquely contained measurable amounts of Radium-226 and its decay products, suggesting contamination.^[3] Its age has been estimated at 4.64 billion years.^[5]
