GK2 record combines archived Saha et al. (2021), Saha et al. (2019) and Saha et al. (2018a) data. BaCa & YCa values are identical (accounting for rounding) between datasets but SrCa record differs. The more recently published Saha et al. (2021) SrCa record was used for the GBRCD SrCa record.

Slices were pre-treated with 10% hydrogen peroxide for 48 hr to oxidise organics and subsequently ultrasonically rinsed and oven dried. Manually collected using a drill with a 2 mm diameter bit to collect a minimum of 12 sequential samples per annual band (8-12 samples per annual band as per Saha et al. 2018b). JCp-1 & analytical precision reported from Saha et al. (2021). See Saha et al. (2021) supplementary for all analytical precision results. Complete machine details as per Saha et al. (2021) is Thermo X-series II ICP-MS with a CETAC - 500 auto-sampler, electron spray PC3 Peltier cooled cyclonic spray chamber and SC-FAST injection loop. REEs measured.
