It is a specialized course that deals with the study, analysis, and interpretation of tectonic structures and deformation at the small scale of observation, i.e., from the scale of a few meters (layer/fracture level), to the microscopic scale (mineral or mineral assemblage level). The main field of Microtectonics focuses on studying thin sections under the microscope, which are also an essential source of information.
Basic concepts and methods. The working framework of Microtectonics; Flow and deformation. Brittle, plastic and ductile deformation. Stress and strain; Deformation mechanisms. Pressure solution, Grain Boundary sliding Subgrain rotation, Grain Boundary migration; Foliations. Primary and secondary foliations observed in rocks. Bedding, Cleavage, Schistocity, Gneissic foliation; Lineations. Stretcing, intersection and crenulation lineation; Fault Rocks. Classification of fault rocks based on descriptive criteria. Cataclasites, Mylonites, Gneisses; Shear zones. Definition, Geometry and kinematics of shear zones; Structures in dilation sites. Porphyroblasts Veins, pressure shadows, pressure fringes, boudins; Sampling How to sample rock specimens and construct thin sections for a microscopic scale study.
