Programa
This course is an introduction to quantitative structural geology using the concept of stress and strain. Main goal: to train participants in reading and quantifying deformation from natural rocks at all scales.
| Day 1 morning |
Introduction to the concept of strain. Behaviors of passive marker lines (rotation, length change) during ductile deformation (lecture: PowerPoint presentation). |
| Day 1 afternoon |
Exercises for strain quantification from constructed examples and pictures of deformed natural rock using measurements of length change and angular relationships (auxiliary material: compass, ruler, pocket calculator). |
| Day 2 morning |
Progressive deformation of natural rocks and three dimensional deformation. Emphasize is put on the resulting structures, e.g. extension gashes, flanking structures, rotated porphyroclasts and refold structures (lecture: PowerPoint presentation). |
| Day 2 afternoon |
Exercises deciphering progressive deformation from constructed and natural extension gashes, flanking structures and rotated porphyroclasts. Exercises on three-dimensional deformation structures (boudinaged folds, folded boudins and refold structures) and the limit of the concept of plane strain (auxiliary material: compass, ruler, pocket calculator). |
| Day 3 morning |
Introduction to the concept of stress, force balance and brittle deformation (lecture: PowerPoint presentation). |
| Day 3 afternoon |
Fault slip analysis of brittle deformed rocks using the stereonet (auxiliary material: tracing paper, stereonet, thumbtack). |
| Day 4 morning |
Microtectonics: Crystal plastic processes, ductile creep and cataclasites. An insight into rheology of geomaterials (lecture: PowerPoint presentation). |
| Day 4 afternoon |
Rheological experiments using analogue materials (auxiliary material: starch, plasticene). Exercises using optical microscopes (auxiliary material: thin sections, microscopes). |
| Day 5 morning |
Advanced topics on quantitative structural geology using Mohr Circles, Stress- and Stream- Functions (lecture: PowerPoint presentation). |
| Day 5 afternoon |
Quantification of natural stress and strain problems using various kinds of Mohr Circle constructions (auxiliary material: compass, ruler, pocket calculator). Computer lab using standard software (e.g. Microsoft Excel, Mathematica and/or MatLab). |
