Earths Sedimentary Rocks and Environments
This course includes theoretical and practical presentation of depositional environments and sedimentary processes, and their recognition in the rock record by using the sedimentologic and sequence stratigraphic techniques.
The topics of the course are organised to introduce Earth's sedimentary rocks and their environments of deposition in a logical progression:
1. Familiarisation with the concept of facies and facies models and their practical applications;
2. Familiarisation with sedimentary structures, how these relate to transport processes and their applications in sedimentary geology;
3. Provision of an overview of the principles of stratigraphy;
4. Introduction to the microscopic petrological description of sedimentary rocks.
- Semester 2 - 2017
On successful completion of the course students will be able to:
1. Demonstrate an understanding of the classification systems for sedimentary rocks;
2. Demonstrate an understanding of sedimentary structures and their importance in the interpretation of depositional environments;
3. Understand the concept of facies, facies models, facies associations and how these are related to depositional environments;
4. Demonstrate an understanding of facies models for continental (fluvial), marginal-marine (coastal, deltaic, estuarine) and marine (shelf and deep water) depositional environments;
5. Understand the role of climate, eustacy and tectonics in the development of facies and facies associations;
6. Understand provenance and transport processes of clastic sedimentary rocks;
7. Demonstrate a knowledge of the techniques for the characterisation of sedimentary rocks;
8. Present and interpret data from sedimentary grain populations;
9. Understand diagenetic processes and features in sedimentary rocks;
10. Demonstrate practical interpretive and descriptive techniques in sedimentary microscopy and petrography.
The objectives of the course are met by providing theoretical background on the controlling factors resulting in production, transport and deposition of siliciclastic sedimentary rocks resultant sedimentary structures. Facies analysis and sequence stratigraphic techniques are employed for the reconstruction of past depositional environments. The course content includes:
- The concept of facies, facies models and facies models and their practical application.
- Sedimentary structures and how these relate to transport processes and their applications in sedimentary geology.
- The principles of stratigraphy.
- Introduction to microscopic petrological description of sedimentary rocks.
Field-based and microscopy laboratories provide the necessary link between theory and observation and interpretation of ancient and modern sedimentary environments.
