equivalent 1st year petrology course
Delivered over two semesters
This module aims to extend knowledge of the characteristics of igneous rocks and
metamorphic rocks, understand the applications of trace elements, stable and
radiogenic isotopes in their interpretation and to understand how these rocks
formed in relation to plate tectonics and Earth evolution.
By the end of this module, students should be able to:
1. identify common igneous rock types in hand specimen and using a petrological
microscope, and explain the basis of igneous rock classification
2. interpret igneous phase diagrams and explain the formation of igneous rocks in
terms of melting and crystallisation processes
3. explain the evolution of bulk rock chemistry as a result of melting, assimilation
and fractional crystallisation, and describe the use of trace elements and
isotopes in igneous petrology
4. explain the formation of textural features in igneous and metamorphic rocks
and how they are used to interpret geological history
5. describe the metamorphic changes in a range of rock types under a range of
physical conditions, the use of metamorphic phase diagrams to infer the
conditions of formation of a given mineral assemblage, and to interpret the
metamorphic history of an area in terms of a P-T-t path
6. discuss the relationship between magmatism, metamorphism and plate
tectonics
7. produce a report on the basis of data provided and interpretation of
observations
Classification of igneous rocks; melting and crystallisation process in magmas;
formation of igneous textures; trace elements and isotopes in petrology; formation
of basaltic, intermediate and granitic magmas; P-T, T-X, P-X diagrams; plotting
metamorphic rock compositions in AFM and ACF diagrams; basic chemical
thermodynamic controls on metamorphic reactions; metamorphism of pelites,
limestones and basalts; interpretation of metamorphic textures; tectonic
environments of metamorphism and relationship to magmatism and plate tectonics.
Practical work on the petrology of specimen suites from metamorphic and
magmatic environments and interpretation of data sets derived from igneous and
metamorphic rocks.
Lectures, laboratory practical classes, directed study and assessment.

Igneous and metamorphic rocks comprise the bulk of the continental crust.
Understanding the composition and formation of these rocks is important as they
preserve records of the evolution of the Earth and its tectonic regimes. This module
explores the origin of these materials and how they provide an insight into the
Earth's internal processes, a subject of ongoing scientific investigation and debate.
