Syllabus
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

References
shear zone, its formation, rock textures, shear zone related features, Shear sense indicators.

folding. Grain scale deformation. Crystallization vs. Deformation, Rock microstructures.
