Planet Earth was formed 4,560 Ma and its differentiation into crust, mantle and core occurred shortly thereafter. Continuous magmatism in various plate tectonic settings, in combination with processes related to melting and magma differentiation, has led to the wide spectra of igneous rock distinctive of Earth’s crust. We learn to use phase equilibria and geochemical-isotopical characteristics of igneous rocks to achieve a deep understanding of these processes in different tectonic environments. We also learn the principles for absolute dating of minerals and rocks. In addition to lectures, exercises in microscopy, geochronology, chemical calculations and seminars will be undertaken. An excursion along the coast of SW Sweden, including visits to island in the Göteborg archipelago, will take place early in the course.
|In the field we will study rocks and discuss their petrology.||The impresseive McKenzie dyke swarm of Canada, which originated from a mantle plume 1275 Ma ago|
