Learning Objectives
By the end of this teaching unit, the student will be able to:
1. Know and Understand (Basic Cognitive Level)
- Define key concepts in tectonics: stresses, deformations, tectonic forces, geological structures.
- Explain the origin of stresses and their effects on rocks.
- Differentiate between tectonic deformations (folds, faults, thrust sheets) and non-tectonic deformations (creep, landslides).
- Describe the structural elements of folds (hinge, limbs, axial plane) and faults (throw, fault plane, fault blocks).
- Classify different types of folds (symmetrical, asymmetrical, recumbent) and faults (normal, reverse, strike-slip).
2. Apply and Analyze (Intermediate Level)
- Analyze geological maps and cross-sections to identify tectonic structures (folds, faults, unconformities).
- Interpret deformation mechanisms based on field observations or models (e.g., sense of movement along a fault).
- Relate geological structures (thrust sheets, joints) to regional tectonic settings.
- Apply microtectonic concepts to describe small-scale deformations.
3. Evaluate and Create (Advanced Level)
- Reconstruct the tectonic history of a region using complex geological data (overlapping structures, cross-cutting relationships).
- Develop hypotheses on the structural evolution of an area by integrating concepts of continuous/discontinuous deformation.
- Write a structured scientific report based on the analysis of real-world case studies (practical work).
Specific Objectives for Practical Work (TP)
- Be able to read and annotate geological documents (maps, cross-sections, block diagrams).
- Master graphical representation techniques for structures (tectonic symbols, standardized legends).
- Defend tectonic interpretations orally/in writing using geological evidence.
Pre-requisites

- Stress and strain in the Earth's crust (brittle vs. ductile deformation).
- Major types of geological structures: folds, faults, joints.
- Introduction to geodynamic processes (subduction, continental collision, rifting).
2. Structural Geology
- Principles of rock deformation.
- Techniques for analyzing geological structures in maps.

Chapter 1 – Concepts of Stress and Strain
This chapter introduces the fundamental principles governing how rocks respond to tectonic forces. It covers the differences between force, stress, and strain, as well as the geological sources of stress that shape Earth's crust.
Chapter 2: Non tectonic deformation
This chapter examines Earth surface processes that cause rock and sediment deformation without tectonic forces. These are primarily driven by gravity, water, and weathering, shaping landscapes through gradual or sudden mass movements.
