The rocks were tested as whole-rock samples using K-Ar dating and also separated into individual minerals. The whole-rock and separated mineral samples allow a method known as isochron dating to be done. This method is supposed to eliminate the assumption that the initial concentration of the daughter element is zero.
This is supported by the presence of large amounts of helium in some minerals. Evidence for the period of accelerated decay is found in zircon crystals. Want to watch this again later?
