Description

This course focuses on modern sedimentary environments, oceanography and marine organisms as a key to interpreting depositional environments, and the techniques and approaches that allow geologist to deal with geological time. The fundamental underpinning is stratigraphy, and using sedimentary features and fossils as palaeoenvironment indicators, with particular attention paid to New Zealand examples.

This course focusses on sedimentology and stratigraphy as a record of Earth’s changing landscapes, depositional environments, and climates through time.  Modern sedimentary environments are used as a key to interpreting the past, as are the techniques and approaches that allow geologists to deal with geologic time. The course opens with lectures and laboratory classes that introduce the principles of fluid flow, sediment transport, and sedimentary depositional environments and how these processes affect the texture and composition of sedimentary rocks. The course then moves on to carbonate sedimentology and oceanography, and the interpretation of carbonate environments. The interaction of biota with substrates is introduced with trace fossils and the preservation potential of different fossil groups. Students will learn how sedimentary features, along with fossils, are used to interpret past environments in Earth’s history.

The topics coved by this course are:
• Sediment transport processes and sedimentary textures
• Terrestrial and marine depositional environments
• Clastic and Carbonate sedimentology
• Basic principles of oceanography
• Use of microfossils in stratigraphy, and modern and ancient environment analysis
• Trace fossils in marine environments
• Sequence-, litho- and biostratigraphy.

Learning Outcomes

  • Goal of the Course - For students to be able to describe siliciclastic and carbonate sedimentary rocks and interpret depositional environments, then to apply these interpretations to understanding stratigraphic successions and how landscapes change through time.

    Learning Outcomes -  Students will:
  • Have developed an understanding of sedimentary processes occurring at the surface of the Earth.
  • Be able to classify and identify common sedimentary rocks in both hand specimen and under the microscope.  
  • Be able to use sedimentary and biofacies analysis to interpret ancient environments and to reconstruct palaeogeography.
  • Be able to interpret and correlate stratigraphic columns from a variety of data.
  • Be able to recognise and utilise important fossil groups used in NZ Cenozoic environmental interpretation.

      • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:

      Critically competent in a core academic discipline of their award

      Students know and can critically evaluate and, where applicable, apply this knowledge to topics/issues within their majoring subject.

      Employable, innovative and enterprising

      Students will develop key skills and attributes sought by employers that can be used in a range of applications.

      Globally aware

      Students will comprehend the influence of global conditions on their discipline and will be competent in engaging with global and multi-cultural contexts.
