Steens Basalt Sr, Nd, Pb, Hf, Os, and O Isotopic Compositional Data

Nicole Moore, Anita Grunder, Wendy Bohrson, Richard Carlson & Ilya Bindeman
This dataset presents analyses of Sr, Nd, Pb, Hf, Os, and O whole rock and mineral isotopic compositions for a suite of basalts from the type section of the Steens Basalt at Steens Mountain in southeast Oregon, and other regional outcrops of the Steens Basalt. The Steens Basalt (~16.9 Ma) is the oldest and most mafic member of the Columbia River Basalt Group (CRBG), the world’s youngest continental flood basalts. These data help further characterize...
