Objectives and Content
The course gives an introduction to sedimentology and sedimentological methods. The course commences with an overview of weathering processes and their importance in forming sediments and sedimentary rocks. The following topics will subsequently be covered: sediment transport, depositional processes, sedimentary textures, mineral composition, classification and formation of the most important sediment types, depositional environments, and sedimentary basins.
The exercises will focus on how sediments and sedimentary structures are formed, and how to identify various sedimentary rocks and their depositional environment.
A 6 days field course in southern Spain in late October where the student will be introduced to sedimentological field methods and various sedimentary deposits, and how these might signal climatic conditions, sealevel changes and basin development.
On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
- can explain what a sedimentary basin is
- can explain the difference between physical and chemical weathering
- can explain the connection between weathering, erosion and sediment composition
- has basic knowledge of principles in fluid dynamics relevant for transport and deposition of sediments
- can explain how the different sedimentary structures are formed
- can explain how sediments are transformed into sedimentary rocks
- can explain the difference between how siliciclastic sediments and carbonate sediments are formed
- can explain why diagenetic processes operate differently in siliciclastic and carbonate deposits
- can explain the formation of various carbonate deposits
- can explain the formation of various evaporite deposits
- can explain the formation of shales, sandstones and conglomerates
The student will learn how to
- use precise geological terms in describing and discussing sedimentary structures, textures and processes.
- identify the main types of sedimentary rocks such as mudstones, sandstones, conglomerates, limestones and evaporites
- interpret sedimentary processes based on the composition of the rock and sedimentary structures
- identify the depositional environment (i.e. continental; shallow and deep marine)
- identify sedimentary deposits that are characteristic of various types of sedimentary basins
- will acquire a basis for further studies in sedimentology and sequence stratigraphy
- can conduct fieldwork in accordance with the HSE regulations at GEO/UiB
