Module Learning Aims:

This module aims to develop an understanding of structures in three dimensions by introducing the principal means of presenting structural data, namely maps, cross sections and stereographic projections. The mapping component of the module aims to provide the basic background to geological cartography and how to undertake geological mapping at a variety of scales.

Module Content:

This module examines the geometries, kinematics and mechanics of rock deformation.  It also deals practically with the representation of three-dimensional structural data using maps, cross-sections and stereographic projections.  It also introduces the principles and methodology of geological mapping at a variety of scales including topics such as map projections, coordinate systems and Global Positioning Systems (GPS).

Learning outcomes:

On successful completion of this module students should be able to:

  • summarise the basics of rock rheology, the concepts of stress and strain, and the processes of brittle and ductile deformation
  • classify and identify rock fabrics, faults, fractures and fault zone rocks and describe and classify folds
  • give a detailed account of the principal features of compressional, strike-slip and extensional tectonic systems
  • confidently present and manipulate data using stereographic projection
  • confidently navigate and locate themselves in the field, use compass-clinometers correctly
  • produce their own base and geological maps using hand-held GPS, and outline the principles behind their construction.
