Pb isotope results of acid-reductive leaching of late Miocene bulk sediments from ODP Leg 161 Site 978. Uncertainties in the table are internal measurement uncertainties reported to 2 SE. One sample produced a strikingly different result; to confirm, a new measurement was performed on a new portion of sediment. An average value of these measurements is provided.
Age uncertainty for all values ranges from 6.12 Ð 6.62 Ma based on R. rotaria, see also section Methods ODP Site 978. For measurement repeated on this sample; average of analyses given.
