€ FysGeo 4200 - Case study in Physics of Geological Processes€
This course will involve a field, laboratory and/or simulation based case study. A specific geological problem will be investigated from start to finish using advanced quantitative methods. The course will include: Quantitative field observations including 3D mapping and collection of rock samples; Data analysis using e.g. image processing techniques; Interpretation of results in terms of relevant geological processes; Laboratory and numerical modeling of these processes; Synthesis and presentation of project results.
Autumn 2007 Theme: 'Fragmentation patterns and processes'
1. Introduction to geological problem:
Investigation of impact breccia associated with Gardnås Meteorite impact
2. Quantitative field observations:
Detailed mapping to characterize spatial distribution of damage at different scales, collection of field samples, photo-analysis.
3. Analysis of field data:
Damage intensity analysis. Image analysis of field photographs. Particle size and shape distributions of breccia fragments using image analysis of hand specimens and thin sections (SEM, probe). Core analysis (400m gardnås core).
4. Interpretation of results:
Comparison of results to theoretical fragmentation models. Estimate of energy associated with impact. Attempt to constrain strain rate, confining pressure, history.
5. Modelling:
Experimental and/or numerical modeling of fragmentation and impact processes
6. Reporting:
Short article summarizing background, methods, data analysis and interpretation of results, modeling of processes, integration of data and models, interpretation with respect to previous work.
