Title

Pb and Nd isotope data for Tropic Seamount correlated Fe-Mn crust stratigraphy (NERC Grant NE/M011151/1)

Abstract

The file contains the validation data on certified reference material for Nd isotope measurement, the LA-MC-ICP-MS composite Pb isotope ratios and Nd isotope time series for Tropic Seamount, north-east Atlantic Ocean. The dataset spans a deposition history covering the last 75 Ma. The record was obtained by analysis of hydrogenetic ferromanganese crust samples recovered during the 2016 JC142 expedition of the MarineE-Tech project.

Quality and validity

Lineage

All powdered subsamples were leached in closed vessels using 2.5 M HCl on a hot plate overnight. Rare earth elements were concentrated using columns packed with Eichrom AG50x8 cation exchange resin, and Nd was then separated using Eichrom LN-SPEC resin. Nd solution isotope measurements were performed using a ThermoScientific Neptune Plus multicollector inductively coupled plasma mass spectrometer (MC-ICP-MS) coupled to a Teledyne-Cetac Technologies Aridus II desolvating nebuliser and an ESI SC-micro autosampler with PFA-50 nebuliser tip. Nd was corrected for mass fractionation using 146Nd/144Nd = 0.7219. Pb isotopes were measured by laser ablation (LA-MC-ICP-MS) on samples thin section by rastering a letterbox format ablation spot across the stratigraphy (See main text for details).
