Magmatism and Metamorphose II

Abstract

This course represents the continuation of Magmatism and Metamorphism I and concerns the generation and evolution of igneous rocks as well as the metamorphism of igneous and sedimentary rocks as products of geodynamic processes operating within the Earth´s interior.

Objective

The course is a continuation and further deepening of the contents presented in Magmatism and Metamorphism I. This course combines petrography, geochemistry, experimental and theoretical petrology as well as petrophysics to assess fundamental igneous and metamorphic processes controlling the generation and evolution of igneous and metamorphic rocks in time and space. Here the following themes and relationships are presented and detailed: Principles of (1) chemical systems and reactions; (2) Intraplate magmatism; (3) the role of oxygen fugacity in Earth material´s cycles; (4) physical properties of magmas and their impact on magma segregation, differentiation, ascent and emplacement . A quantification of igneous and metamorphic processes (the latter mainly on meta-basalts) based on modal mineralogy, geochemistry, phase petrology and thermodynamic principles is assessed and further promoted in the accompanying homework and exercises.

Content

- Principles and fundamental understanding of chemical systems and reactions ("Schreinemaker") - Alkaline intraplate magmatism (hot spots and rifts) - Oxygen fugacity: Reduction and oxidation of Earth materials and the deep mantle - Structures and physical properties of melts and magmas - Metamorphism of basalts - LMI – Layered mafic intrusions – Example of magma differentiation
