Unit 3053: Structural Geology Fundamentals

1. Introduction to Structural Geology

• Definition and scope of structural geology
• Importance of studying rock deformation
• Overview of geological structures: faults, folds, joints
• Forces shaping the Earth's crust: tectonic forces and stress fields

2. Stress and Strain in Rocks

• Definitions:
  • Stress: compressional, tensional, shear
  • Strain: elastic, plastic, brittle
• Stress-strain relationship and rock behavior
• Measurement and representation of stress and strain
• Factors influencing rock response: temperature, pressure, rock type

3. Rock Deformation Mechanisms

• Brittle deformation:
  • Characteristics and examples
  • Fracturing and faulting
• Ductile deformation:
  • Characteristics and examples
  • Folding and flow
• Influence of conditions on deformation mechanisms (depth, temperature, strain rate)

4. Faults and Faulting

• Definition and significance of faults
• Types of faults:
  • Normal faults
  • Reverse (thrust) faults
  • Strike-slip faults
• Fault characteristics: fault plane, hanging wall, footwall
• Processes of fault formation and movement
• Role of faults in crustal deformation and seismic activity

5. Folds and Folding

• Definition of folds and their significance
• Types of folds:
  • Anticlines
  • Synclines
