Hafnium isotopes in Eastern North American tholeiites of the Central Atlantic Magmatic Province
This file contains 176Hf/177Hf isotope measurements for a suite of Central Atlantic Magmatic Province (CAMP) magmas (201 Ma), focused on tholeiites from the Eastern North American (ENA) region and particularly southern ENA. When compared with published results for the same rocks, these samples form a shallow sloped array on a epsilon-Hf vs. epsilon-Nd diagram, where the low 143Nd/144Nd samples have more radiogenic 176Hf/177Hf than the terrestrial array. The least radiogenic samples in epsilon-Nd and epsilon-Hf also have relatively low 206Pb/204Pb ratios.
