This course is devoted to understanding the environmental processes that form sediments and sedimentary rocks, and how we go about interpreting past environments and processes from the sedimentary record.
1. Clastic Rocks (>80%)
They are particles derived from the weathering and erosion of precursor rocks and consist primarily of fragmental material and are classified by grain size and composition. Clastic rocks are the most common i.e. mudstones (65%) and sandstones (20-25%)
What is a sedimentary rock? Sedimentary processes. Classification of Sediments and Sedimentary Rocks. Characteristics of sedimentary rocks. Sorting, Roundness. Sphericity. Color. Sediment maturity. Composition. Provenance. Sedimentary textures. Clastic Depositional Environments.
2. Biochemical Sediments and Sedimentary Rocks. (represents about 10 - 15% of sedimentary rocks)
Biogenic Carbonate Mineralogy. Limestone texture. Types of carbonate grains. Classification of carbonate rocks. Carbonate diagenesis. Carbonate Environments. Biochemical chert. Diatomite.
3. Chemical Sediments and Sedimentary Rocks.
Evaporite deposits. Evaporite precipitation order of seawater. Depositional environments. Ferrous deposits. Origin and transport of Fe. Depositional basins. Phosphorite deposits. Types of phosphorite deposits. Depositional environments. Siliceous deposits. Residual deposits.
4. Principles of Sedimentary rocks.
Principles of sediments is used to know more information about the characteristics of sedimentary rocks that are deposited in basins.
Principles of Sedimentary rocks can be classified into:
Principle of superposition
Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top.
Principle of original horizontality
The deposition of sediments in a horizontal way which is their relief angle.
Principle of lateral continuity
The layers of sediments extend in all directions If there is no any restrictions on their ways.
Principle of cross-cutting relationships
Any intrusive/cutting rock or layer is younger than the layers of sediments.
4. Sedimentary Structures
Sedimentary Bedding and Structure. Bedding patterns. Sediment transport mechanisms. Types of fluid flow. Types of sedimentary structures.
5. Plate Tectonics and Sedimentary Rocks.
6. Sedimentary basins.
Facies concept. Facies associations. Facies analysis. Facies model.
Mineralogy and Stratigraphy
