CEG2602 : Rock Materials: the petrology of igneous, sedimentary and metamorphic rocks

Semester 1 Credit Value: 10
ECTS Credits: 5.0


The aim of this course is to give students the opportunity to learn what is needed to describe rocks in terms of the materials from which they are made, and to understand the processes of their formation. As a single course it allows connections to be made between igneous, sedimentary and metamorphic processes, thus expressing a connection within the dynamic Earth system. The course will equip students for independent work, especially in the field description of rocks, and includes development of practical skills in observation (microscope work) and data interpretation that are important in the Earth Sciences at all levels.

Outline Of Syllabus

The course is based on the structure of a well-established text book (Blatt, Tracy and Owens ‘Petrology’), which is aimed at students at this stage. In three parts, the first and largest component introduces the rock forming minerals and the igneous rocks in which these are formed, in the context of the geological setting. This provides an opportunity to introduce simple phase diagrams, as well as quantitative methods of rock analysis and their interpretation.

The second component addresses the weathering of igneous rocks and the formation of sedimentary rocks, giving students the opportunity to classify and describe these as is done in the petroleum industry as well as more widely.

The third component addresses metamorphic rocks, and looks at how these are formed from sedimentary rocks (and some igneous rocks) in response to changes in pressure and temperature. Students will have the opportunity to learn geobarometry and geothermometry as tools used to determine the conditions of formation of these rocks.

All of this is in the context of the overarching paradigm of Plate Tectonics.

In addition to characterising minerals and rocks in hand specimen, thin section work will support lectures for all three components, supplemented by paper exercises that involve handling data and plotting graphs that are widely used to interpret rock compositions.

Teaching Rationale And Relationship

Lectures are required to provide a framework for the development of learning and acquisition of knowledge.
The practical classes are vital for the acquisition of the skills that the module needs. A student will use the practical skills gained from this module throughout their entire career. The practical sessions involve opportunities for relationship building and articulation of a problem, through informal contact with teaching and demonstrating staff, as well as with peers.
The work is focused on a substantial textbook, and students will be required to read around the subject to supplement work done in lectures and practicals.
