Evidence of multi-phase Cretaceous to Quaternary alkaline magmatism on Tore-Madeira Rise and neighbouring seamounts from 40Ar/39Ar ages.

The Tore-Madeira Rise is a seamount chain located 300 km off the Portugal and Morocco coastsattributed to hotspot activity. U-Pb ages of lavas from the northern and central Tore-Madeira Rise rangebetween 103 and 80.5 Ma whereas 40Ar/39Ar ages from the central and southern Tore-Madeira Rise yield age...
