Erosion, transportation and deposition of sediments; depositional environments and sedimentary facies. Mineralogy, texture and structures of sediments and sedimentary rocks. Tectonics of sedimentation. Mineral deposits associated with sediments and sedimentary rocks.
Sediments are the key recorder of earth surface processes and environments through time. This will be an integrated field, laboratory and lecture paper designed to link sediments to their respective processes and environments. A key focus will be an investigation of fundamental techniques available for describing and deciphering the process and depositional history of sediments, including the analysis of facies, textures, sedimentary petrography and physical properties of modern and ancient sediments. The paper will also investigate a series of depositional environments and indirect controls on their deposition (such as climate, sea level and tectonics). Course material will cover both terrestrial and marine sedimentary environments, processes and materials.

- ((GEOL 112 or GEOX 112) and (EAOS 111 or EAOX 111)) or (18 GEOL points and GEOG 101)
- GEOL 373
- Schedule C
- GEOL 273 is for students in their second year of a geology or equivalent degree. GEOL 373 is for students in their third year of a geology or equivalent degree.
- Teaching Arrangements
- Two lectures and one 3-hour laboratory per week.
Fieldwork: Two weekend day trips (back to back) along the South Otago Coast.
- Paper Structure
- The course has four elements:
- Fundamental processes in sedimentology (fluid theory, settling, wave theory, wind, ice and diagenesis);
- Depositional environments (alluvial fans and river systems, lakes, glacial and aeolian systems, clastic shorelines, deltas and shelves);
- Tools for sedimentary investigations (observation and description, facies analysis, textural analysis, sedimentary petrography, physical properties, sediment coring); and
- Controls on sedimentation ( direct - currents, waves, wind, density flows & settling, and indirect - climate, sea-level, tectonics).
Assessment is approximately an even split between internal (ongoing during the semester) and external (final exam). Assessments for GEOL 373 are set and graded differently to GEOL 273 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
