  • Mineralogical data relating to carbonate-bearing fluorapatite from the Bukusu, Catalao II, Sokli, Kovdor and Glenover carboantite complexes. Report on the data is here: Broom-Fendley, S., Siegfried, P.R., Wall, F. et al. The origin and composition of carbonatite-derived carbonate-bearing fluorapatite deposits. Miner Deposita 56, 863-884 (2021). https://doi.org/10.1007/s00126-020-01010-7.

  • 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.

  • This dataset contains Sequential extraction analyses of rock and soil samples from the Sokli carbonatite laterite, 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 different mineralogical hosts of the REE and their behaviour on leaching. The analysis were carried out by teams from the School of Applied Sciences, University of Brighton.

  • Database of samples collected or utilised in the project SCREED: Supergene enrichment of carbonatite-hosted REE deposits. Samples were collected from Sokli (Finland), Miaoya (China), and Longonjo (Angola) carbonatite complexes. Archival materials were also collected from the Mushgai Khudug (Mongolia), Tomtor (Russia), and Dong Pao (Vietnam) carbonatite complexes. Samples were collected either as field grab samples, with locations determined by handheld GPS, or from archive drill core provided by Sokli Oy, Finland and Pensana Ltd., Angola. Samples were collected through weathered carbonatite materials into the upper bedrock. Samples from Sokli and Lonjongo specifically targeted REE-enriched, thick (40-100m) lateritic materials from sites undergoing active mineral exploration for supergene REE resources. Samples from Miaoya targeted incipiently weathered materials, including clays from a carbonatite-syenite complex, to characterise early stages of weathering and contrasting weathering styles. Samples from Tomtor and Dong Pao represent REE mineralised material from additional lateritic REE deposits. The samples were acquired by teams from the School of Applied Sciences, University of Brighton and Camborne School of Mines, University of Exeter, with the assistance of staff from Sokli Oy (Finland) and Pensana Ltd. (Angola), and collaborators from the China University of Geosciences and the Institute of Geology, Chinese Academy of Geological Sciences (China).

  • Analyses of archive rock and soil samples from the Mushgai Khudug (Mongolia), Dalucao, Miaoya and Lizhuang (China) rare earth element deposits. Data characterise mineralogy, bulk rock geochemistry and sequential leaching experiments on laterite, weathered rock and soil overlying carbonatite related REE deposits. The data was collected to determine enrichment and depletion of the REE relative to bedrock, the mineral host of REE and the ease of extraction.

  • This dataset contains Electron microprobe analyses of monazite, rhabdophane, crandallite and pyrochlore from the Sokli carbonatite laterite, 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 changes in mineral chemistry during weathering. The analysis were carried out by teams from the School of Applied Sciences, University of Brighton and Camborne School of Mines, University of Exeter
