Structural Geology Theory
Scope Crustal deformation occurs through a wide range in scale. The manifestation of deforming forces leaves its signature in thousands of kilometers wide lithospheric plates, as well as in slip at the atomic scale of the crystal lattice of individual mineral grains. In the structural Geology theory course, the objective is to familiarize with the description, classification, and recognition of various geologic structures as well as study the processes responsible for the formation of these structures in the macro and micro scale. Course Content Introduction: Description and formation of beds/lithounits/formations/groups, concept of uniformitarianism, Attitude of Planes and Lines, Stereographic Projection. Rock deforming forces, revision of the concept of plate tectonics; a brief introduction to stress and strain; rheology. Fold: Geometry, nomenclature, Fold forms, Outcrop pattern in map, view in plan and section, stereographic projection, Scale of folding, congruous and incongruous folds, Classification of folds. Primary sedimentary structures : Nomenclature and genesis of only those primary structures that are used in the determination of younging direction of lithounits. Fault and Joint: Geometry, nomenclature and genesis. Slip and separation. Unconformity: definition, classification. Comparison of fault and unconformity. Foliations and Lineations; Morphology and types of foliations and lineations. Mesoscopic and microscopic characters of cleavages. Strain significance of cleavages. Mechanisms of cleavage development. Significance of linear structures. Geometry and development of boudinage structures. Tectonites. Stress and Strain. Shear Zones: Brittle and ductile deformation. Definition of |
