Heavy rare earth elements (HREE) are critical for the transition to net zero in addition to being key to manufacturing defense technologies. Unconformity-related rare earth element (REE) deposits represent an important source of HREE, including key elements such as dysprosium (Dy) and terbium (Tb). Given the strategic importance of these critical minerals to the national economy, a national-scale mineral potential assessment h...

This research documents the paleoenvironmental evolution of Eighteen Mile Swamp on North Stradbroke Island (Minjerribah), Australia, from oscillating coastal lagoon into stable freshwater swamp over the last ca. 1600 years. We analyzed multiple sediment cores via physical description, acid sulfate soil assays, particle size analysis, diatom and pollen assemblages, photosynthetic pigment content, and Itrax XRF spectrometry, alo...
