P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.

Abstract In the changing Arctic, permafrost thaw is shifting from gradual to abrupt. Although iron‐bound organic carbon (OC‐FeR) critically modulates permafrost carbon‐climate feedbacks, its decadal‐scale variability and response to this regime shift remain poorly constrained.
