OBJECTIVES
- Participants in this seminar will become familiar with the tectonics of folded and thrust belts, as well as the kinematic models of folds related to faults, enabling them to interpret these structural styles.
CONTENTS
- Folded and Thrust Belts (FTB): Introduction. Nomenclature of structures within an FTB: Types of folded and thrust belts. Thin-skinned and thick-skinned thrusts. Formation mechanisms (Coulomb wedge) and zoning of an FTB. Out-of-sequence thrusts (OST). Foreland basins and their utility for understanding the deformation history of the FTB.
- Thrust Systems: Imbricated systems. Duplex systems. Triangular zones.
- Geometric and Kinematic Models of Folds Related to Faults. Fault-bend-folding. Interstratal shear. Fault-flexure folds with simple and pure shear. Fault-propagation folds with constant thickness, fixed hinge (non-constant thickness), area-balanced, and transported folds.Detachment folds.Fault-propagation folds of triangular shear. Key parameters of the trishear model
- Stereographic Projection. Diagrams of maximum circles vs. pole diagrams. Obtaining the axis of a fold. Calculating the axis and axial plane of a fold. Cylindrical vs. conical folds. Contours using Schmidt's method and Kamb's method. Kinematic indicators. Calculation of P and T axes
