Abstract

The location of the Canary Archipelago, at the east edge of the North Atlantic, a few hundred kilometres from the West African coast. has For years posed a serious difficulty in understanding the complex interaction between long-lasting volcanic activity and one of the oldest seafloor basements (>150 Ma) on earth. Many different hypotheses have been proposed in the lost two decades to understand the genesis of the Canary Archipelago. There is anincreasing acceptance to explain the archipelago as the product of the slow passage of the African plate over a mantle hotspot. In rival tectonic models, stretching and thinning of the lithosphere would determine the islandsas independent volcanic blocks. We review recent geophysical and geological evidence supporting a mantle plume origin for the Canary Islands, based on the recognition of crustal thickening by mafic intrusions produced by theinteraction between the mantle plume and the old oceanic lithosphere beneath the Canary Archipelago.
