For SdT-09-ash1 61 zircons were prescreened of which nine (15%) were young magmatic zircons; for SdT-09-ash5 66 zircons were prescreened of which eight (12%) were young magmatic zircons (see ‘'Methodology' – U/Pb dating of volcanic ashes’ section for explanation of the prescreening analysis routine).
