The process of volcanism will be examined using observations of volcanic features and deposits on the terrestrial planets and satellites and the basic principles of physical volcanology. Predictions made on the basis of the theory of magma generation, ascent, and eruption will be compared to the observations of the planetary geologic record of volcanism. Attention will be focused on the influence of different variables (e.g., gravity, composition, temperature, pressure, and atmospheric effects) on the landforms, modes of emplacement, and the geologic record of volcanism. The comparative historical records of planetary volcanism will be studied in relation to planetary thermal and geodynamic evolution. The approach will be two-fold: We will work systematically through the textbook (Principles of Physical Volcanology, Parfitt and Wilson) to gain a fundamental understanding of physical volcanology. In parallel the class will also consider the geological record and diversity of volcanic landforms and deposits on the terrestrial planetary bodies, commonly interlinked with the Chapter theme.
