DESCRIPTION - summary of the module content
AIMS - intentions of the module
An overview of the causes and mechanisms of naturally occurring deformation within the lithosphere and the recognition, nomenclature, formation, representation and analysis of the principal types of geological structure, and their implications for applied earth science and earth resources engineering.

SYLLABUS PLAN - summary of the structure and academic content of the module
Term 1 Data collection/representation (Weeks 1-2): Measurement and representation of orientation data; introduction to stereonet projection Stress (Weeks 3-4): definitions. Origins of lithospheric stress. Stress at a point; principal stresses; tensor notation; deviatoric, mean and hydrostatic stress. Equations for σn and σs under plane stress conditions; representation of 2D state of stress using a Mohr circle. Concept of effective stress. Methods of in-situ stress determination Deformation (Weeks 5-6): components of deformation; homogeneous versus heterogeneous deformation; continuous and discontinuous deformation. Longitudinal strain and angular shear strain parameters. Volume changes. Principal strains, strain ellipsoid and strain ellipse; special types of strain ellipsoid and Flinn plots. Pure shear and simple shear. Progressive deformation. Strain analysis; circular and elliptical markers, lines, centre to centre technique Rheology (Weeks 6-7): experimental evidence for influence of T, P, strain-rate, fluid pressure, anisotropy and composition upon rheology; problems of extrapolating to lithosphere Deformation mechanisms (Weeks 8-9): grain boundary sliding, fracturing/cataclasis, diffusive mass transfer, and crystalline plasticity Term 2 Global tectonics (Weeks 1-2): geometry of structures, associations of sedimentary, igneous and metamorphic rocks in zones of divergent, convergent and strike-slip tectonics Fractures (Weeks 3-4): Experimental and theoretical studies of brittle failure • Joints and veins. Occurrence, geometry, terminology and significance Faults and faulting (Weeks 5-6): Occurrence, geometry, terminology and significance of extensional, contractional and strike-slip fault zones. Fault rocks (cataclasites and pseudotachylites). Evaluation of fault displacement. Neotectonics and seismicity Brittle-ductile and ductile shear zones (Week 7): Occurrence, geometry, terminology, sense of shear criteria and significance for fluid flow/mineralization. Fault rocks (phyllonites and mylonites) Folds and folding (Weeks 8-9). Occurrence, geometry, terminology and significance. Facing and vergence. Stereogram representation. Cleavages and lineations. Polyphase deformation. Refolded folds and interference patterns. Secondary cleavage fabrics and transposition Tectonic and structural controls upon igneous intrusion (Week 9): Sills and dykes; granitoid plutons • SW England case study: extensional, contractional and strike-slip tectonics, granite emplacement, mineralization and the development of sedimentary basins.
