Olivine tholeiites (8–10 wt. % MgO) from Krafla show significant correlations between major elements (notably Fe) and incompatible trace elements. In particular, the samples with the highest Fe contents are the most enriched in elements such as K, Ti, and light rare earth elements (LREE s ). The obs...
