Origin of ocean island basalts in the West African passive margin without mantle plume involvement
The genesis of hotspot magmatism remains controversial especially at continental margins such as offshore West Africa. Here, by analysing trace element and Pb isotopes of intraplate basalts, the authors conclude that their generation was caused by the melting of two fusible regions of subcontinental...
