Magmatic and metamorphic petrology of a fossil subduction zone on Syros, Greece

The island of Syros in the Cyclades is one of the few examples in Europe where a fossil subduction zone is well exposed. Cretaceous to Eocene peak metamorphic conditions reached 500°C at about 1.5 GPa total pressure. The aim of the project is to identify the nature of the protoliths, unravel possible primary lithostratigraphic relationships, and to date emplacement and metamorphic overprint ages. The long-term project involves extensive field work combined with U/Pb, Rb/Sr and Ar/Ar dating of magmatic and metamorphic minerals. Work is being carried out in cooperation with John Schumacher (Bristol University), Igor Villa (University of Bern), and Allan Kennedy (Curtin University, Australia). The project presently supports three diploma and one Ph.D theses at the University of Münster.
