Rise and Fall of a Multi-sheet Intrusive Complex, Elba Island, Italy

Abstract

The western Elba igneous system is a prime example of a full range of emplacement styles at a single magmatic center, with successive generation of a nested set of multilayer laccoliths, a downward-developing amalgamated pluton, an extensive throughgoing dyke swarm, with a final collapse of the whole complex triggered by the overwhelming thickness of magma added to the uppermost crust in a short time.
