Geochemical data from volcanic rocks drilled in deep sea drilling project (DSDP) leg 81 site/hole 555 in the Rockall Plateau of the northeast Atlantic Ocean

NdData.csv 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 lavas (from Macintyre and Hamilton, 1984). Errors on discrete measurements are 2 and 1 standard error (SE). XRF_PETM.csv Analysis of major and trace element compositions of volcanic tuffs from DSDP Site 555 in the northeast Atlantic. Note that Mg# = 100 x molecular MgO/(MgO + FeO), where FeO is assumed to be 0.9FeOT.
