We present whole-rock major and trace element compositions of dykes and lavas from the Masirah Ophiolite (Oman). The data cover several sites within the two ophiolite nappes that are exposed on Masirah Island off the south-east coast of Oman and were collected during a 2018 field campaign as part of MJ's PhD project. The samples are fairly primitive and variably altered basalts that follow MORB differentiation trends and have varying degrees of immobile trace element enrichment. Together with crosscutting relationships observed in the field, these data show that D-MORB and E-MORB magmatism was contemporaneous at the Masirah palaeo-MOR spreading centre. The interpretation and discussion of these data form part of a manuscript submitted to Geochemistry, Geophysics, Geosystems.
