Global context of magmatism and systematic description and quantitative interpretation of volcanic and plutonic rocks; phase equilibria and geochemical constraints on petrogenesis; physical processes of magma transport and eruption.

'Igneous Petrology and Volcanology' covers the systematic description and quantitative interpretation of volcanic and plutonic rocks within a plate tectonic framework. We emphasise examination of selected igneous suites in hand sample and thin section. You will learn to interpret phase equilibria, deposit characteristics, geochemical, textural, microtextural, and geochronologic features to interpret magma petrogenesis and controls on its emplacement at depth or eruption at the surface. Important mineral and geothermal resources are associated with igneous rocks, and the paper includes discussion of genetic relations between magmatic, geothermal, and ore-forming processes.

Paper Structure
  • Upper mantle structure, composition and partial melting; origin and differentiation of magmas at oceanic spreading ridge, rift and intraplate settings; trace element and isotope constraints on magma sources
  • Magma's physical characteristics, crustal magma transport, lava emplacement, effusive and explosive eruptions
  • One-day field trip to examine volcanic rocks of East Otago
  • Origin and differentiation of magmas in subduction zone settings; crustal partial melting; magma-related hydrothermal systems
  • Two-day field excursion to examine igneous rocks of the South Coast
Assessment is approximately an even split between internal (ongoing during the semester) and external (final exam).
Assessments for GEOL 364 are set and graded differently to GEOL 264 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
