The MexiDrill core was dated using a range of methods, including radiocarbon. Samples of sediment were pretreated (acid-only) at the 14CHRONO Centre according to established protocol, and measured using Accelerator Mass Spectrometry (AMS). The plain-text file lists the uncalibrated AMS radiocarbon dates, with the following columns: UBA ID, date submitted, MexiDrill sample ID, radiocarbon age, and lab error.

We undertook U-Pb analysis - both high precision ID-TIMS and high spatial resolution LA-MC-ICP-MS – to determine the age of the Wensleydale Granite. This was done in order to resolve the ambiguity surrounding an earlier (1974) Rb/Sr age determination.

The dataset contains three subsets: 1) W isotope data for reference materials and geological samples, 2) Pb isotope data for reference materials and geological samples and 3) Mo isotope data for reference materials and geological samples. The data was collected over a period of about two years in two different laboratories (University of Manchester and University of Bristol) using multi-collector ICPMS techniques. A description of the methods used to obtain the W and Mo isotope data can be found in Willbold et al. (2011) and Willbold et al. (2016). The determination of the Pb isotope data is detailed in Freymuth et al. (2016). The data of reference materials (standard solutions and geological reference materials) is used to assess the reproducibility and accuracy of the mass spectrometric setup at the time and used as uncertainty estimate for the geological sample data.

The data forms the basis of the paper Novella et al (2020 (https://doi.org/10.1016/j.epsl.2019.115973) and full interpretation can be found there. Basalt glass chips were supplied by Bramley Murton (Southampton) and the sample contexts are detailed in https://doi.org/10.1093/petrology/43.11.1987. New trace element data is provided for the clean basaltic glasses (all reported in ppm). The Vanadium isotope composition (del51V) is also reported for these chips. Uncertainties in these analyses are provided as 2-sigma. Updated estimates of the ferric iron content of these chips also provided, based on recalibration of the data reported by Shorttle et al 2015 (https://doi.org/10.1016/j.epsl.2015.07.017).

This dataset contains major, trace, and volatile element contents, and sulfur isotope ratio data measured in silicate glasses found in volcanic rocks from the Central American Volcanic Arc.

UKCCSRC Call 2 Project C2-189. The data, which was produced as a result of a UK CCSRC Call 2 funded project, consists of the GC-MS characterisation results for the products collected from the rejuvenation tests of degraded amine sorbents from carbon capture and related model degradation compounds. The examined amine-based sorbent samples included one heavily degraded industrial MEA solvent, one degraded solid-supported polyethyleneimine sample and 6 model MEA degradation compounds (N-(2-Hydroxyethyl)-ethylenediamine, glycylglycine, 2-Oxazolidinone, 1-(2-Hydroxyethyl)-2-imidazolidinone, 1-(2-Hydroxyethyl)-imidazole, N-Acetylethanolamine. Novel reductive approaches, which were investigated as a potential means for rejuvenating the degraded amine sorbents and where the samples for characterisation were produced, included catalytic hydrogenation, hydrous pyrolysis and hydropyrolysis with platinum, nickel and molybdenum as the catalysts used. The dataset also contains some preliminary CO2 absorption test results for a degraded MEA solvent before and after rejuvenation with hydrous pyrolysis using a continuous reactor. Full technical details of the research are contained in the final report submitted to UK CCSRC.

Sample locations and geochemical data from the Aurora Ni-Cu-PGE magmatic sulphide deposit, Northern Bushveld Complex, South Africa. Samples were taken from two boreholes on the La Pucella farm, courtesy of Pan Palladium Limited. This data contains petrological photographs; scanning electron microscope element maps and identification of platinum group minerals and precious metal minerals; and trace element concentration of ore minerals. This data was collected as part of the TeaSe consortium NERC grant in order to determine the concentration and hosting of critical and precious metals in various types of ore deposits and barren rocks from different geological environments. This data was collected and interpreted by researchers at Cardiff University and is used in a paper, available at https://doi.org/10.1016/j.oregeorev.2019.02.008.
