Hydrogen and Oxygen Isotopic Compositions of Sedimentary Clay in the Sea Region off the Western Antarctic Peninsula and Their Material Sources
Abstract In the geochemical study of sedimentation, hydrogen and oxygen isotope data are useful for a discussion on formation conditions and material sources of sediments. Hydrogen and oxygen isotope analyses were made on clays separated from the sea‐floor surface sediments at 9 stations in the west...
