Abstract:
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 the three-stage evolution of the Steens Basalt magmatic system, by elucidating mantle source components that contributed to magma generation, as well as crustal processes that modified the magmas during ascent through and storage within the crust prior to eruption.
