Title of PhD: The stratigraphy, sedimentology and provenance of the Gwna mélange deposits of the Monian Supergroup, Anglesey and north-west Wales

Supervisors: Professor Ian Fairchild, Dr James Wheeley, Professor Paul Smith (Oxford University), Dr David Schofield (British Geological Survey)

Rosemary is undertaking research into the deposits of the Gwna mélange within the framework of the wider Monian Supergroup setting to establish the age and mode of emplacement of this controversial unit through sedimentological and chemostratigraphic methods. The Monian Supergroup was formed in the midst of a tectonic cycle responsible for the formation, breaking up and reformation of continental masses during early Earth history. As a result the diminutive island of Anglesey appears to consist of several terranes. A further aim is to correlate the mélange constituent lithologies with their provenance terranes in order to further deconstruct the palaeogeographic history.
