Course objectives:
Students acquire basic knowledge of igneous rocks and fundamental igneous petrogenetic processes.
Students develop basic skills for the independent identification, determination and classification of igneous rocks using standard petrological techniques.

Course content (syllabus):
1) Basic concepts: structure of the Earth, data sources, pressure and temperature changes at depth, igneous activity as part of the rock cycle.
2) Physical and chemical properties of magma. Polymerisation. The role of volatiles. Igneous cycle.
3) General anatomy of a volcanic system from source to surface. Forms of igneous bodies. Volcanism.
4) Igneous rock forming minerals. Textures and structures. Mineralogical classification systems.
5) Hybrid and chemical classifications. Application of geochemical data. Igneous rock series.
6) Thermodynamics in igneous systems. Phase diagrams, melting and crystallisation of magmas.
7) The mantle as the source of basaltic magmas. Melting mechanisms of the mantle in relation to geotectonic setting. Partial melting.
8) Processes that influence the primary composition of magma: differentiation, assimilation, mixing.
9) Igneous activity at divergent plate boundaries. Processes associated with mid-ocean ridges. Formation, structure and composition of the oceanic crust.
10) Igneous activity at convergent plate boundaries I. Anatomy of the subduction zone. Subduction-related processes. The role of subduction zones in the generation and evolution of the Earth's crust.
11) Igneous activity at convergent plate boundaries II. Ocean island arcs. Volcanic arcs.
12) Igneous activity in collisional settings.
13) Granites. Classification. Modes of occurrence.
14) Within-plate igneous activity. Oceanic islands. Basaltic provinces.
15) Continental rifts. Alkaline magmatism within plates.
