The Canary Islands Hot Spot
نویسنده
چکیده
The Canary archipelago comprises seven main volcanic islands and several islets that form a chain extending for ~ 500 km across the eastern Atlantic, between latitudes 27°N and 30°N, with its eastern edge only 100 km from the NW African coast (Figures 1 & 2). The Canary Islands developed in a geodynamic setting characterized by Jurassic oceanic lithosphere formed during the fi rst stage of opening of the Atlantic at 180-150 Ma and lying close to a passive continental margin on a very slow-moving tectonic plate – the African plate. In addition, the archipelago lies adjacent to a region of intense active deformation comprising the Atlas mountains, a part of the Alpine orogenic belt.
