High-resolution LA-MC-ICP-MS Pb isotope data (65.5 - 63 Ma) for Tropic Seamount, north-east Atlantic, and Matlab and R processing scripts for cyclostratigraphic analysis (NERC Grant NE/M011151/1)

The excel table presents the high-resolution LA-MC-ICP-MS Pb isotope data (± 2S%) produced for the Paleocene interval of Fe-Mn crust core sample 085_004 recovered in 2016 during the JC142 expedition to Tropic Seamount for the MarineE-Tech project. A detailed description of the sample can be found in Josso et al., 2019 and 2020. The Scripts data are Matlab and R readable file presenting all scripts and built-in functions used during the processing of the data to demonstrate the presence of astronomical imprint on the cyclicity of the Pb isotope ratios.

Statement: The Pb isotope data was generated by laser ablation and analysed on a Neptune MC-ICP-MS at the British Geological Survey. Data were acquired in continuous transects using a letterbox format (2*150 µm) ablation spot rastering perpendicular to the sample layering at 2 µm/s with one integration every 0.262 seconds. Data were normalised to Nod-A (Baker et al., 2004) as the primary reference material and the data output at the integration level for plotting as a continuous profile. Nod-P, JMn-1 and an in-house material (HRM) prepared from a homogenised quantity of Fe-Mn crust from Tropic Seamount, were analysed during the same sessions to validate the results by comparison to published and/or in-house results determined by solution calibration.
