Prof. Johann Diener
My main research interest is the development and application of mineral equilibria modelling techniques (THERMOCALC) to investigate metamorphic processes. Specific interests are the conditions and mechanisms of migmatisation and melt migration through lower-crustal rocks (with ongoing projects in the Namaqua Metamorphic Complex in South Africa and Namibia), and the interplay of physical and chemical processes during crustal reworking.
