Résumé

The remains of a lava delta occur within the volcanic succession called Serie I Media in the Anaga Massif, in the northeastern part of Tenerife Island (Canary Islands). The outcrop is located in the lower part of the ravine of Igueste de San Andrés, at about 90 meters high. The delta is formed mainly of flows of low viscosity basaltic lavas that cover pillowlavas, roughly resedimented pillow-fragment breccias, and hyaloclastites, in foreset bodies with high dips towards the S. The delta is covered by agglomerates constituted by fragments from the different facies of the delta and levels of lavas and subaerial pyroclasts, formed of small coastal strombolian eruptions.
