Name of subject: Determination of Paleostress Tensors |
Instructors:
Prof. Branislav Trivić |

Status: Optional |
|
ECTS: 10 |
|
Prerequisites: - |
Course Objectives:
The objective of the course is to present contemporary methodologies of statistical interpretation and analysis of disjunctive structural features. The results will be coupled with mathematical and statistical analysis in order to understand their geological context. |
Learning Outcomes:
After completing the course student will be able to collect data on faults, shear joints and shear-zones geometries, their attitude and kinematics. Also, they will analyze relative chronologies of discrete intermittent movements along these structures, based on observed striation or other strain indicators. Finally, the student will offer their own interpretation of the analyzed data. |
Content:
