  2. Igneous Rocks Textures and cooling history Rock names; compositional classification and mineralogical Origin of magmas; decompression, flux and thermal melting Gas content and viscosity; controls and consequences Water content; role in melting and explosive volcanism

  3. Tectonic environments • Basalts; MORB, OIB (intraplate), Flood • Basalts and LIPs, Subduction Zones • Know the controls on the production • of calc-alkaline versus tholeiitic • basaltic magmas • Understand layered intrusions and • processes of mineral accumulation • in a magma chamber

  4. Andesites and Granites; predominantly at subduction zones • Andesites; fractional crystallization versus contamination • Granites; fractional crystallization versus crustal melting • Understand Source, Path and • Evolution !!!
