Credit Points | 12.5 |
Coordinator | Assoc. Professor C J L Wilson |
Prerequisites | Earth Sciences 625-221 and 625-222 (or 625-211 and 625-212 in the 1996 Handbook). |
Semester | 2 |
Contact | 24 lectures (two per week), 24 hours practical work (two hours per week), and 4 days field work (held on weekends during the semester) |
Subject Description | Mechanical aspects of rock deformation; stress and strain behaviour of materials; descriptive treatment of strain folds and cleavage; examination of deformed rocks in the laboratory and in the field. Response of rocks to elevated temperature and pressure; the equilibrium metamorphic model and the facies concept; metamorphic rocks in thin section and in hand specimen; the relationship between mineral assemblages in metamorphic rocks and their conditions of formation. The evolution of pressure, temperature and deformation in orogeny. The acquisition, inversion and interpretation of magnetic, gravity and seismic data in tectonics contexts. Field mapping, including individual mapping projects. On completion of this subject, students should have acquired an understanding of the effects of elevated pressure, temperature and stress on rocks; be able to recognise, describe and interpret rocks formed as a consequence of these effects in the laboratory and in the field and understand the role of geophysical methods in establishing and testing tectonic models |
Assessment | A 2-hour end-of-semester written examination; a 2-hour practical examination or reports totalling up to 1500 words; a 5 page field report. |
