Stable Isotope Geochemistry of Marine Sediments and Paleoenvironments
This community investigates the chemical composition of rocks, sediments, and waters to reconstruct Earth's past climate, ocean chemistry, and biological cycles.
The work centers on stable isotope analysis, particularly strontium, carbon, oxygen, and sulfur ratios, to trace the movement of elements through geological systems. Recurring subjects include manganese oxides, organic carbon preservation, and rare earth element distributions within marine basins. The research frequently examines specific regions, such as the South China Sea and the Pacific Ocean, to understand how iron and manganese minerals interact with organic matter. Methods rely heavily on mass spectrometry and isotope fractionation studies to decode the history of water-rock interactions and sedimentary processes.
The community represents 11.1% of all tracked research on strontium and 6.7% of manganese research, with 2,886 and 2,941 papers respectively.
This group comprises 22,060 papers, published primarily in Geochimica et Cosmochimica Acta, Chemical Geology, and Earth and Planetary Science Letters.
Recent work includes studies on redox-driven mineral associations in Mars, calcium isotope evidence for carbonate precipitation in river catchments, and the decoupling of cerium isotope fractionation in marine sediments.
