  • Evaluating mantle and crustal processes using isotope geochemistry 

    Saal, Alberto E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-09)
    Geochemical studies are fundamental for understanding how the dynamic Earth works and evolves. These studies place constraints on the composition, formation, age, distribution, evolution and scales of geochemically ...
  • Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic 

    Graham, David W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-09)
    The isotopic evolution of helium and lead in the Earth is coupled by virtue of their common radioactive parents uranium and thorium. The isotopic signatures in oceanic volcanic rocks provide constraints on the temporal ...
  • The isotope geochemistry of abyssal peridotites and related rocks 

    Snow, Jonathan E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-06)
    This dissertation studies several aspects of the formation of the Earth's oceanic mantle and crust, using a variety of geologic techniques, principally major elements, radiogenic isotopes and trace elements, but including ...
  • Stable isotope geochemistry of nitrogen in marine particulates 

    Libes, Susan M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-01)
    Isotope studies of nitrogen and carbon were undertaken to investigate the fate of particulate organic matter (POM) during its residence in the water column and after deposition on the seafloor. The processes focused on ...
