GEOL 273/373 students examining an outcrop along the south Otago coastline near the mouth of the Clutha River. Students collect field data from a late Cretaceous-Eocene terrestrial and marine sedimentary sequence to develop a stratigraphic history of the region.
Students logging a section of exposed rock near the Wangaloa Domain along the south Otago coastline.
Details
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.

Professor James White - 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).
Practical work will be based around one field trip and laboratory modules that include modern sediment mapping, grain-size analysis, sedimentary petrography (grain mounts and thin-section), and measurement of physical properties.
Assessment is approximately an even split between internal (ongoing during the semester) and external (final exam). Assessments for GEOL373 are set and graded differently to GEOL273 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.- Teaching Arrangements
Two lectures and one 3-hour laboratory per week.
Fieldwork: Two weekend day trips (back to back) along the South Otago Coast.

- Students will leave the paper with an understanding of the Earth's sedimentary cycle, familiarity with the processes active within it and an understanding of how to extract and interpret the record of past environments that is held in sediments and sedimentary rocks.
