Title

Neodymium isotope, REE, and Percentage CaCO3 data from IODP Expedition 390 and 393: South Atlantic Transect

Abstract

Neodymium (Nd) isotope data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, the normalised 143/144 Nd ratio, the eNd(0) and eNd (t) values for each sample, plus the associated internal errors for normalised 143/144 Nd ratio, the eNd(0). Rare Earth Element (REE) data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, mass of fish debris dissolved for each sample, the concentration of Phosphorous (P) and Calcium (Ca) in ppm, and the concentration of REEs in ppb. Additionally, the concentration of REEs has been normalised to the Post-Archean Australian Shale (PAAS) using values from Pourmand et al. 2012 have been included. Ce anomalies have been calculated using 2 similar methods, plus other REE parameters: LREE, MREE, HREE, MREE*, HREE/LREE, and MREE/MREE*. Percentage Calcium Carbonate (%CaCO3) data from IODP Sites U1557 and U1558 including detailed sample information including 3 depth scales where possible, and weight percentage CaCO3 data.

Lineage

Nd isotope data was generated using the Thermo Scientific Neptune multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) at the University of Southampton. The measured 143Nd/144Nd isotopic ratio is normalisation to the 146Nd/144Nd ratio of 0.7219 and a subsequent correction using the 142Nd/144Nd ratio of 1.141876 to minimise column chemistry fractionation effects. REE data was generated from an aliquot of the each sample used for Nd isotopes. Major and REE concentrations were measured using an Agilent 8800 Triple-Quadrupole ICP-MS (ICP-QQQ-MS) at The Open University. %CaCO3 data was generated by the AutoMate with CM5015 coulometer at the University of Southampton.
