Deep beneath volcanoes lie magmatic systems where magma is formed and evolves. These systems are directly related to plate tectonics and the structure and chemistry of the Earth. This course will study these systems – how they are formed, and why they evolve, as well as what they lead to; volcanic eruptions. This course will use rock specimens, thin sections and geochemistry to study igneous rocks and processes, and will link these processes to the wider tectonic controls on magmatic systems, as well as to metamorphic rocks that are often seen in conjunction with magmatic systems.
