Understanding Atlantic ocean islands: contributions from geodynamics, lithosphere-asthenosphere structure and magmatism
Convener: Jaime AlmeidaECSECS | Co-conveners: Pablo J. Gonzalez, Ana Ferreira, Stéphanie Dumont
Ocean island archipelagos are outstanding natural laboratories in which we can explore the complex interactions between tectonic, magmatic and mantle processes at a wide range of scales, from mantle-lithosphere interactions to outcrop (or smaller) level observations without forgetting the possible influence of interplay with external forcing. Within the Atlantic Ocean, several such sites exist, such as Iceland, the Azores or the Canaries, each with its own unique setting, dynamics and evolution.

This session aims to bring together contributions from geological, tectonic, geophysical, geodetic and geodynamic studies of the Atlantic Ocean islands and archipelagos. We particularly welcome contributions that might have a new perspective or methodological approach that aim to understand the recent
Icelandic rifting unrest and eruptions, the 2022 Sao Jorge Island (Azores) aborted eruption and the 2011-2012 El Hierro or 2021 La Palma eruptions in the Canary Islands.

We also welcome studies or datasets documenting past activity based on geological or geophysical approaches in/around eroded shield volcanoes across the Atlantic islands.
