How rocks being deformed

NettetTypes of Stress. Stresses fall into two categories: normal stress acts at right angles to a surface, and shear stress acts parallel to a surface (Figure 13.2). Normal stress is subdivided into compression, when the stresses are squeezing a rock, and tension, when stress is pulling it apart. Rocks undergo compression in regions where plates are ... NettetDifferent processes can deform rocks, the deformation is almost always the result of stress. This stress leads to the formation of fault and fold structures, both can either extend or shorten of the Earth's crust. Thick-skinned deformation specifically affects deep crystalline rock of the basement and may extend deeper into the lower crust.

NettetUnconformities are simply gaps (missing data) in the rock record, these gaps could indicate a variety of processes. Such as: erosion, deformation, or changes in sea-level.

NettetStages of Deformation. When a rock is subjected to increasing stress it passes through 3 successive stages of deformation. Elastic Deformation -- wherein the strain is reversible. Ductile Deformation -- wherein the strain is irreversible. Fracture - irreversible strain wherein the material breaks.
