    • 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 ...
    • Globally elevated titanium, tantalum, and niobium (TITAN) in ocean island basalts with high 3He/4He 

      Jackson, Matthew G.; Hart, Stanley R.; Saal, Alberto E.; Shimizu, Nobumichi; Kurz, Mark D.; Blusztajn, Jerzy S.; Skovgaard, Anna C. (American Geophysical Union, 2008-04-17)
      We report evidence for a global Ti, Ta, and Nb (TITAN) enriched reservoir sampled by ocean island basalts (OIBs) with high 3He/4He ratios, an isotopic signature associated with the deep mantle. Excesses of Ti (and to a ...
