  • Fuerteventura and Lanzarote islands were created by volcanic processes that took place on the western margin of the triassic rift basin developed during the initial opening of the Central Atlantic. Thick syn-rift deposits consisting mainly of salt-anhidrite, were soon substituted by a deep water paleogeography developed west of the distant shelf, of passive type, built on the african continental margin. Seismic lines and wells inthe area, allow us differentiating the extent, the approximated age and morphological characteristics of the volcanic products that, originated in Fuerteventura and Lanzarote, were intercalated within the sedimentary record of the basin as well as interpreting some of the peculiarities of the Jurassic and Cretaceous outcropping onshore Fuerteventura
