Edificios volcánicos en la Serie I de Fuerteventura: Rasgos generales del edificio central

Abstract

The Old Basaltic Series in Fuerteventura is formed by three main edifices: Northern, Central and Southern (or jandíaJ Edifices. The Central Edifice, a shield volcano, extends from El jable towards Valles Ortega area forming a semicircular shape around a large adjacet basin. The edifice is built up by dipping outwards thick basaltic flows piles in which pyroclastic are scarce. Three different subseries, can be distinguished within these piles: Lower, Medium and Upper Series, all separated by unconformities. A fourth active episode, the Late Series, filled the inner basin, and was clearly emitted after a large tectonic graben took place.
