GEOL 101: Deformation: Modification of Rocks by Folding and Fracturing Stress – force applied to a rock per unit area o Types of Stress Compression – pushed together Tension – pulled apart Shearing moving sideways Strain – change in shape and/or volume of a rock body as a result of applied stresses Strength – ability of an object to resist deformation o Compressive or tensile Deformation of Rocks Folds and faults are geologic structures caused by deformation Structural Geology is the study of the deformation of rocks and its effects How do we measure Deformation? 1. Many rocks occur naturally in layers o Sedimentary rocks o Lava flows o Metamorphic rocks (foliated) 2. Many features within rock bodies are either planar or linear o Minerals o Foliation Strick and dip on a rooftop Dip – angle of steepest descent of the bed form the horizontal Strike – orientation of a horizontal line, at right angles to the dip direction Sample Exam Question Which mineral is commonly used to determine a metamorphic PT path? a. Calcite b. Garnet c. Muscovite d. Quartz
