Northwestern Pacific Fe-Mn Crust Chemical Composition Data

This dataset supports a study on the long-term evolution of seawater chemistry, focusing on geochemical and isotopic variations in marine environments. The dataset includes analytical results from Fe-Mn crust samples, covering major and trace element concentrations, as well as isotopic compositions of Os and Cu. These data were collected to investigate the influence of geological and environmental processes on marine geochemical cycles over extended timescales. The dataset is intended for researchers interested in geochemistry, paleoceanography, and isotopic studies. Files include: Data of main trace elements in Fe-Mn crust and Cu and Os isotopes.
