Lecture Topics
I. Organization, Scope, Goals of Course, Requirements.
II. What is Structural Petrology? Fabrics: Key to mechanisms; Key to linking laboratory mechanical behavior to nature. Concept of Rock Fabric: Fabric elements, subfabrics, homogeneous vs heterogeneous domain, isotropy and anisotropy, penetrative or pervasive deformation. Fabric Data and Statistics: representation techniques, analysis
III. General Rock Behavior Deformation Mechanisms, Mode of Failure, Mechanical Behavior Subsurface conditions - effective pressure, temperature, time, fluids Brittle - ductile transition Relative strength and ductility Deformation Mechanism Maps Overview of Deformation within the Crust and Mantle
IV. Deformation Mechanisms, Recovery, Healing and Recrystallization Mechanisms Resulting microstructures, textural evolution, mechanical behavior evolution Elasticity and Residual Stress in Rock Theoretical Inelastic Strength Flaws in Rocks Brittle Mechanisms Fracture - microscopic, submicroscopic views Intra, Inter, and Transgranular Microfractures Macrofracturing and Faulting Cataclastic Flow Macroscopic Fault Fabrics Stress Corrosion Cracking, Healing and Sealing Fluid-assisted Diffusional Processes Pressure Solution, Stylolite Development, Veins Crystal Defects Crystal Plastic and Solid-state Diffusional Processes Dislocation Glide Twin Glide Folding Crystal Plasticity and Diffusional Processes (Cont.) Recovery Internal Recovery Polygonization Recrystallization Dislocation Creep Textures, fabrics Micromechanics of Flow Laws Defect Chemistry and Deformation Hydrolytic weakening Diffusion Creep Self-diffusion Grain Boundary Sliding Texture Piezometry Deformation during phase transformations Mixed Mechanism Deformation Polyphase and spatial distributions Series and parallel mechanisms Foliation Development Episodic Deformation, stress and strain cycling
