Objectives On the completion of this subject students will be able to characterise sedimentary processes and their products in marine and terrestrial environments; review the interpretation of past depositional environments and tectonic processes; describe and classify large and small scale structural features of deformed rock sequences; outline the structural makeup of orogenic belts; analyse the rheological properties of the crust and mantle.
Synopsis This subject consists of two units run in parallel; both are compulsory. (1) Sedimentation stratigraphy and biostratigraphy. Characterisation of sedimentary processes and their products in marine and terrestrial environments; interpretation of past depositional environments; relationships between depositional environments and tectonic processes; consideration of large scale stratigraphic relationships and changes in sediment types through time; biostratigraphic and palaeoecological inferences of fossil groups, emphasis given to Pre-Cambrian and Palaeozoic faunas. (2) Structural geology, tectonics and hydrogeology. Description and classification of large and small scale structural features of deformed rock sequences; relationships between geometry of structures, and applied stress fields; structural make-up of orogenic belts, the geometry of thrust-belts and extensional terrains in a plate tectonic framework; rheological properties of the crust and mantle; Naviour-Coulomb relations and faulting; ductile creep; crustal extension models; continental collision; deep seismic reflection results.
