This dataset is an additional sample list, as an Excel spreadsheet, providing details of the major sample suites collected by Delia Cangelosi during SoS RARE and not added to the master spreadsheet (https://webapps.bgs.ac.uk/services/ngdc/accessions/index.html#item165705) It includes location details and descriptions for rock samples collected in China and Namibia. Most material is still held by the institutions that did the work, as recorded in the sample list.

Zeta potential measurements of the fluorcarbonate mineral parisite-(Ce), under water, supernatant and collector conditions. Zeta potential measurements can be used to indicate the surface behaviour of a mineral under different reagent conditions. Mineral surface behaviour is important in processing and extracting minerals from their host ore, which can be energy intensive. Parisite-(Ce) is a fluorcarbonate mineral which contains rare earth elements. Rare earth elements are important in a wide range of products from iPhones to wind turbines.

The data are related to the NERC's Security of Supply of Mineral Resources Catalyst Grant NE/L002361/1: MM-FREE - Mineral-Microbe interaction role in concentration and Fractionation of Rare Earth Elements and consist of: 1. document on the research priorities from an industry/stakeholders viewpoint to devise a strategy for building biomining into a real opportunity for mineral extraction of rare earth elements. 2. poster reporting literature review on "Using microbes to recover rare earths with low environmental impact"

Data from experiments on rare earth element leaching from ion adsorption deposits. Columns experiments of leaching from a Madagascar ion-adsorption soil. Six soil columns for two deposit types with different starting/operational conditions. Data reported are the volume, pH and conductivity, and the molar concentrations of each eluate fraction for the metals, ammonia and Cl.

This dataset comprises the structural and chemical characterization of the alkali roasting of Eureka Monazite carried out at the University of Leeds during the SoS RARE project (2015-2018). It includes structural data from X-Ray diffraction and Scanning electron microscopy of samples roasted with sodium bicarbonate, thermodynamic calculations for identification of the phases formed during roasting, cyclic voltammetry measurements of samples in a solution of choline chloride-ethylene glycol with a 1:1 molar ratio with 0,1 mol/L glucose and the chemical composition of the samples analysed by inductively coupled plasma spectroscopy.

Dataset for classification of rare earth element (REE) deposits in Europe.

Zeta potential measurements of rare earth element enriched apatite from Jacupiranga, Brazil under water and collector conditions. Zeta potential measurements can be used to indicate the surface behaviour of a mineral under different reagent conditions. Mineral surface behaviour is important in processing and extracting minerals from their host ore, which can be energy intensive. Apatite is a phosphate mineral which can become enriched with rare earth elements. Rare earth elements are important in a wide range of products from iPhones to wind turbines.

Neodymium (Nd) isotope data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, the normalised 143/144 Nd ratio, the eNd(0) and eNd (t) values for each sample, plus the associated internal errors for normalised 143/144 Nd ratio, the eNd(0). Rare Earth Element (REE) data measured from IODP Site U1556 comprises of detailed sample information including 3 depth scales, mass of fish debris dissolved for each sample, the concentration of Phosphorous (P) and Calcium (Ca) in ppm, and the concentration of REEs in ppb. Additionally, the concentration of REEs has been normalised to the Post-Archean Australian Shale (PAAS) using values from Pourmand et al. 2012 have been included. Ce anomalies have been calculated using 2 similar methods, plus other REE parameters: LREE, MREE, HREE, MREE*, HREE/LREE, and MREE/MREE*. Percentage Calcium Carbonate (%CaCO3) data from IODP Sites U1557 and U1558 including detailed sample information including 3 depth scales where possible, and weight percentage CaCO3 data.

This dataset contains bulk rock geochemical analyses of rock and soil samples from the Sokli carbonatite complex in northern Finland, generated as part of the SCREED: Supergene enrichment of carbonatite-hosted rare earth element (REE) deposits project. Full sample locations and descriptions are available at https://doi.org/10.5285/83819b57-4754-4da3-9336-955e817573ed. Samples were analysed between September 2024 and October 2025 to determine the chemical change on weathering, and the degree of enrichment of the REE relative to bedrock concentrations. The analysis were carried out by research teams from the School of Applied Sciences, University of Brighton.
