143Nd/144Nd and associated εNd measurements of tuffs, lavas and hyaloclastites from DSDP Leg 81 Site 555. The sample ID number includes the site number (555), core box reference (e.g., 65-1), and the depth from the top of a given core (in cm). The 143Nd/144Nd ratios and associated εNd values are corrected to an age of 55 Ma. Also provided are published 143Nd/144Nd and associated εNd measurements from Site 555 lavas73. Errors on discrete measurements are 2 and 1 standard error (SE).
