Reversed Inter-Mineral Fe-Zn Isotope Fractionation in Ophiolitic Peridotites: Evidence for Widespread Hydration of Oceanic Lithospheric Mantle

Ben-Xun Su, Yan Xiao, Jing Wang, Qi-Qi Pan, and Shou-Qian Zhao

Fluid-assisted element exchange and subsolidus diffusion in various lithologies of the oceanic lithospheric mantle produce reversed inter-mineral isotope fractionation

Dependence of River Water Lithium Isotope Ratios on Watershed Attributes Complicates Interpretation of Weathering-Driven CO₂ Drawdown

Evan J. Ramos, Preston Cosslett Kemeny, Mark A. Torres, and Tomas N. Capaldi

Heterogeneous Carbonate Lithium Isotope Records Across the End-Permian Mass Extinction Indicate a Highly Perturbed Lithium Cycle in the Early Triassic

Kaitlin Taylor, Sofia Rauzi, Terry Isson, Daniel E. Ibarra, Dominik Hülse, Sara R. Kimmig, Jonathan L. Payne, Demir Altiner, Daniel J. Lehrmann, Boriana Kalderon-Asael, Noah J. Planavsky, and Kimberly V. Lau

Variations in Early Triassic carbonate lithium isotopes are hypothesized to reflect diagenetic alteration and a poorly mixed oceanic Li reservoir that developed from extensive reverse weathering

Carbon Isotope Trends of Precambrian-Cambrian Carbonates in Southwestern Laurentia Are Robust to Diagenetic Overprinting

Mary C. Lonsdale, Anne-Sofie C. Ahm, Lyle L. Nelson, Jacob W. Thompson, John A. Higgins, and Emily F. Smith

Carbon isotope (δ¹³C) stratigraphic trends across the Precambrian-Cambrian boundary in southwestern Laurentia are insensitive to diagenetic overprinting despite an increase in fluid-buffered marine diagenesis
