Students will examine the geological evolution of two geologically contrasting Greek islands: Syros (metamorphic) and Santorini (volcanic). The unit builds on previous field classes and will provide specific experience in describing and interpreting rock and deposit types they have not seen before.
The island of Syros is Fransciscan-type metamorphic terrane. This part of the unit will provide specific experience and develop skills in recognising and recording metamorphic assemblages and evidence of complex deformation associated with the subduction process. The Syros component of the unit is based around projects and evaluations in which field data that includes mapping and petrologic observations in metamorphic rocks are collected and then analysed to address specific questions about the metamorphic evolution of the island.
The Santorini component of the unit emphasises field and physical volcanology. It introduces, in a unique field setting of a flooded caldera with up to 300m cliffs, all the main volcanic rock types and facies, and several types of volcanoes. It also shows how to deduce the means and processes of eruptions from analysis of the ejected volcanic debris. The main aims are to: 1) introduce the field sedimentology, petrology/geochemistry and stratigraphy of typical volcanic rocks, and 2) analyse eruption dynamics and long-term volcano evolution.
On successful completion of the unit the student will be able to:
Fieldwork
There is no formal exam.
Before the unit students should look at rock collections in the School lab to review hand specimen identification of volcanic and metamorphic rocks, minerals and fabrics.
