Stable Isotope Geochemistry of Sedimentary Basins and Marine Environments
This community investigates the chemical and isotopic signatures preserved in rocks, sediments, and water to reconstruct past climate conditions, trace the origins of organic matter, and understand the movement of elements through Earth's systems.
The work centers on measuring stable isotope ratios—particularly carbon, oxygen, strontium, and sulfur—within sedimentary basins, marine environments, and continental settings. Researchers frequently apply mass spectrometry to analyze trace elements and rare earth elements in organic matter, carbonates, and silicate minerals. A significant portion of the literature focuses on specific regions, including South China, the Pacific Ocean, and the China Sea, often examining how isotopic fractionation records environmental changes from the Iron and Bronze Ages through the last glacial period. The recurring themes involve linking isotope compositions to climate change, water cycles, and the geological history of basin formations.
The community constitutes a substantial share of research tracked for Strontium (10.3% of all Strontium research, with 4,011 papers here), Sulfur (3.6% of Sulfur research, with 3,348 papers here), and Iron (2.6% of Iron research, with 2,792 papers here).
The community comprises 63,912 papers, publishing most frequently in Geochimica et Cosmochimica Acta, Chemical Geology, and Earth and Planetary Science Letters.
Recent work includes studies on heavy metal toxicity in past biodiversity crises, calcium isotopic evidence for carbonate precipitation in river catchments, and the decoupling of cerium isotope fractionation in marine sediments.
