Objectives On the completion of this subject students will be able to describe and classify the common igneous and metamorphic rock types in hand specimen and thin section; review the behaviour of major and trace elements in natural magmas as a function of magmatic processes; understand the relationships between distinctive mineral assemblages and physical/chemical variables during metamorphism.
Synopsis This subject deals with the chemistry and physical properties of common igneous rock groups and their parental magmas. Behaviour of major and trace elements during crystallisation of natural magmas and simple analogues. Development of characteristic mineral assemblages and textures during metamorphism in varied settings. Relationships between distinctive mineral assemblages and physical and chemical variables during metamorphism.
