Fault and Joint Development

Foreword1. Brittle Fracture Introduction Stress Elasticity Strength of Brittle Material Influence of Petrology on Uni-axial Strength Influence of Environmental Factors on Brittle Failure Relationships between Principal Stresses at Failure Navier-Coulomb Criterion of Brittle Failure Griffith Criterion of Brittle Failure Crack Propagation Microseisms Time-strain Time-strain Mechanism in Semi-brittle Material Long-term Strength in Tri-axial Compression2. Faults Introduction Fault Nomenclature The Navier-Coulomb Criterion and the Angle of Fracture Dynamic Classification of Faults Anisotropy and Shear Failure Further Conditions of Strike-slip Faulting Structures Associated with Strike-slip Oblique-slip Faults Over Thrust Faulting and Pore-water Pressure Thrust Development in Fold Belts Faults in Sediments Due to Movement in the Basement Complex Criticism of Using the Brittle Failure Criteria in the Faulting Problem3. Joints Introduction Classification of Joints Relationship of Joints to Other Structures Surface Features Joint Movement Origin of Joints Joint Frequency Jointing in-folded Rock Pinnate or Feather Joints Inter-relationship of Joint Sets Jointing in Igneous Rocks Columnar Joints Sheet Joints Joints-brittle FracturesIndex
