Abstract:
Ocean island volcanoes constitute some of the most prominent and rapidlyformed features on the Earth’s surface. They are the direct result of a mass and
energy transfer from the Earth’s interior to the surface, making an ideal place to
study mantle/surface interactions. Additionally, islands and island chains are
some of the best places to study the processes of biological colonization,
evolution and speciation, especially when there is a fossil-rich geological record
to back studies based on modern biological communities. Thus, to understand
the geological evolution of oceanic islands and to recognize its main processes
and products is of key importance for someone developing research on
palaeogeography, palaeontology or palaeobiogeography on oceanic islands,
since one process is not independent of the other.
This workshop is intended to offer an overview on the main processes, structures
and products associated with each stage of the evolutionary history of oceanic
islands, with an additional emphasis on the role of biological colonization. The
workshop will also focus on examples from the Macaronesian archipelagos
(Madeira, Cape Verde and the Azores).
Aims and workflow:
At the end of this workshop, the participants should:
 Be able to identify the main stages of oceanic island evolution, their main
characteristics and controlling factors;
 Be able to identify the main eruptive styles and products, commonly found
on oceanic islands;
 Be able to identify some of the most commonly found sedimentary
deposits on oceanic islands;
 Have an overview on some of the differences and similarities between the
Macaronesian archipelagos.
This workshop will be structured through a series of lectures, practical sessions,
round tables and a field trip. In the final round-table, all participants will be
encouraged to show in PowerPoint presentations their fieldwork and their main
achievements and difficulties related with the main theme of the workshop: the
evolution of oceanic islands.
