- Description:
- This dataset evaluates geologic trends in and controls on rare earth element (REE)-enrichment of coal in eastern Utah. 1945 bituminous coal samples from 68 mine, core, and outcrop localities from the Blackhawk Formation (n = 378) and Ferron Sandstone (n = 1567) in eastern Utah were geochemically evaluated using portable X-ray fluorescence (n = 1945) and inductively coupled plasma-mass spectrometry (n = 100) to quantify REE content. Using coal as a secondary REE source could bolster global REE production, leveraging existing coal infrastructure to alleviate CM supply chain bottlenecks and couple traditional coal geology with the innovative resource needs of the future.

- Description:
- This study aims to quantify rare earth element enrichment within coal and coal-adjacent strata in the Uinta Region of Utah and western Colorado. Rare earth elements are a subset of critical minerals used for renewable energy technology in the transition toward carbon-neutral energy. This data contains samples from seven active mines and seven stratigraphically complete cores within the Uinta Region, geochemically evaluated via portable X-ray fluorescence (n=3,113) and inductively coupled plasma-mass spectrometry (n=143) elemental abundance methods. Historical evaluations of geochemical data on Uinta Region coal and coal-adjacent data are sparse, emphasizing the statistical significance of this study’s analyses. These results support the utilization of active mines and coal processing waste piles for the future of domestic rare earth element extraction, offering economic and environmental solutions to pressing global demands.
