| 651-4041-00L | Sedimentology I: Physical Processes and Sedimentary Systems | W+ | 3 credits | 2G | V. Picotti | |
| Abstract | Sediments preserved a record of past landscapes. This courses focuses on understanding the processes that modify sedimentary landscapes with time and how we can read this changes in the sedimentary record. | |||||
| Learning objective | The students learn basic concepts of modern sedimentology and stratigraphy in the context of sequence stratigraphy and sea level change. They discuss the advantages and pitfalls of the method and look beyond. In particular we pay attention to introducing the importance of considering entire sediment routing systems and understanding their functionning. | |||||
| Content | Details on the program will be handed out during the first lecture. We will attribute the papers for presentation on the 26th, so please be here on that day! | |||||

| Prerequisites / Notice | The grading of students is based on in-class exercises and end-semester examination. | |||||
| 651-4043-00L | Sedimentology II: Biological and Chemical Processes in Lacustrine and Marine Systems Prerequisite: Successful completion of the MSc-course "Sedimentology I" (651-4041-00L). | W+ | 3 credits | 2G | V. Picotti, A. Gilli, I. Hernández Almeida, H. Stoll | |
| Abstract | The course will focus on biological amd chemical aspects of sedimentation in marine environments. Marine sedimentation will be traced from coast to deep-sea. The use of stable isotopes palaeoceanography will be discussed. Neritic, hemipelagic and pelagic sediments will be used as proxies for environmental change during times of major perturbations of climate and oceanography. | |||||

| 651-4901-00L | Quaternary Dating Methods | W | 3 credits | 2G | I. Hajdas, M. Christl, S. Ivy Ochs | |
| Abstract | Reconstruction of time scales is critical for all Quaternary studies in both Geology and Archeology. Various methods are applied depending on the time range of interest and the archive studied. In this lecture, we focus on the last 50 ka and the methods that are most frequently used for dating Quaternary sediments and landforms in this time range. | |||||
| Learning objective | Students will be made familiar with the details of the six dating methods through lectures on basic principles, analysis of case studies, solving of problem sets for age calculation and visits to dating laboratories. At the end of the course students will: 1. understand the fundamental principles of the most frequently used dating methods for Quaternary studies. 2. be able to calculate an age based on data of the six methods studied. 3. choose which dating method (or combination of methods) is suitable for a certain field problem. 4. critically read and evaluate the application of dating methods in scientific publications. | |||||
| Content | 1. Introduction: Time scales for the Quaternary, Isotopes and decay 2. Radiocarbon dating: principles and applications 3. Cosmogenic nuclides: 3He,10Be, 14C, 21Ne, 26Cl, 36Cl 4. U-series disequilibrium dating 5. Luminescence dating 6. Introduction to incremental: varve counting, dendrochronology and ice cores chronologies 7. Cs-137 and Pb-210 (soil, sediments, ice core) 8. Summary and comparison of results from several dating methods at specific sites | |||||
