|651-4231-00L||Basin Analysis||W+||3 KP||2G||S. Willett, T. I. Eglinton, M. Lupker|
|Kurzbeschreibung||The course discusses the formation and development of different basin types as part of lithosphere geodynamics. It introduces conceptual models and governing physics, with practical application to the study of basin evolution. Techniques for the analysis of subsidence and thermal history are demonstrated. Organic matter, petroleum play, and their biogeochemical investigation are examined.|
|Lernziel||Based on the introductory education and practical training during this course, each participant should be able to choose and apply approaches and techniques to own problems of basin analysis, and should be versed to expand their knowledge independently. |
In particular, each participant should:
- Develop an intuitive understanding for origin, dynamics, and temporal evolution of basins in a geological / geodynamic context;
- Acquire the necessary theoretical foundation to describe basin evolution quantitatively;
- Be familiar with geological and geophysical methods that are applied to obtain information about rock properties, structural geometry, and thermal and subsidence history of basins;
- Understand the burial and maturation of organic matter in basins, the development of petroleum play, and be acquainted with geochemical methods to study the evolution of biogenic carbon.
|Inhalt||The following topics are covered: |
- Introduction; classification schemes and types of basins; heat conduction; geotherms;
- The lithosphere; isostasy; rifts and basins due to lithospheric stretching; uniform extension model; modifications to the uniform stretching model; dynamics of rifting.
- Elasticity of the lithosphere; flexural compensation; geometry and analytical description of loads and the resulting deflection; foreland basins; their anatomy;
- Reconstruction of basin evolution; borehole data; porosity loss and decompaction; backstripping; subsidence curves; thermal history and its reconstruction;
- Petroleum play concept; organic production; source rock prediction and depositional environment; petroleum generation, expulsion, migration, alteration; reservoir and traps;
- Carbon cycle; maturation of organic matter; geochemistry of biogenic carbon; biomarkers; analytical techniques
- Overview of other basin types: effects of mantle dynamics, strike-slip basins.
Each week of the course is split in lectures and corresponding practicals, in which the concepts are applied to simplified problems.
Grading of the semester performance is based on submitted practicals (50%) and a final exam (50%). The exam will take place in the time slot of the last practical (18.12.).
|Skript||Lecture notes are provided online during the course. They summarize the current subjects week by week, and provide the essential theoretical background.|
