Fluid Inclusions as Ancient Seawater Archives

We directly measure major, minor, trace elements, and isotopes in fluid inclusions trapped in marine halite.

• Techniques: LA‑ICP‑MS; cryo‑SEM‑EDS; microthermometry
• Targets: [Li], δ⁷Li, [Ca], [SO₄], Sr and trace metals
• Applications: secular seawater trends; hydrothermal vs. weathering controls
