Most samples were disaggregated and washed over a 63 µm sieve, and the resultant fine-fraction (i.e.,<63 µm) and bulk samples were analyzed by conventional stable isotope techniques. Please note, that on 2017-06-09 it was discovered that the age values were given as "ka" alhough the values were "Ma". The data are now recalculated (x1000) to fit the unit.
