TheBeardsley meteorite is ameteorite that fell inBeardsley, Kansas, on October 15, 1929.[1][2] Three samples were preserved, one collected the following day, atMichigan State University, and two collected two years later, at theSmithsonian Institution andArizona State University.[3]
It is achondritic type,[4] but the samples showed unusualradionuclide profiles when analyzed in 1962: the Michigan State University sample was unusually high inpotassium (higher than any other chondrite),rubidium (higher than any other meteorite), andcaesium, while theSmithsonian Institution sample uniquely contained measurable amounts ofRadium-226 and its decay products, suggesting contamination.[3] Its age has been estimated at 4.64 billion years.[5]
