Title

Zircon U-Pb Sediment provenance data for Miocene to recent sediments collected at Site U1521 during International Ocean Discovery Programme (IODP) Expedition 374 to the Ross Sea, Antarctica. (NERC Grant NE/R018219/1)

Abstract

This dataset comprises zircon U-Pb data on 11 samples, each containing ~90-150 individual grains. This method was applied to sediment samples from IODP Expedition 374 Site U1521 to the Ross Sea, collected on the RV JOIDES Resolution. Shipboard biostratigraphy and magnetostratigraphy suggests the samples are mainly early Miocene in age (McKay et al., 2019). The uppermost samples do, however, include younger Plio-Pleistocene sediments. Samples were measured using an Agilent 7900 laser ablation inductively-coupled plasma mass spectrometer (LA-ICP-MS) with a 25-35 µm pit diameter in the London Geochronology Centre at University College London.

Zircons from the <300 µm fraction were concentrated using standard gravity settling and magnetic separation techniques. Samples were then mounted in resin, polished and analysed using an Agilent 7900 LA-ICP-MS. Plešovice zircon (Sláma et al., 2008) was used as a primary standard to correct for instrumental mass bias and depth-dependent inter-element fractionation. Approximate U and Th concentrations were calculated by comparison with NIST 612 glass (Pearce et al., 1997). Data reduction of the time-resolved mass spectrometer data was performed using GLITTER 4.5 (Griffin, 2008). Ages younger than 1100 Ma were calculated using the 206Pb/238U ratio whilst older grains used the 207Pb/206Pb ratio. Data were filtered to exclude non-zircons based on zirconium concentrations and a -5/+15% discordance threshold was applied. Final data were processed using IsoplotR (Vermeesch, 2018).
