This topic surveys structural geology from a complete view of recent plate tectonic movement through the use of modeling of ancient tectonic processes. The topic includes: stress and strain, folds, faults, joints, and fractures. It also describes several structural styles, including those that involve compressional, extensional, and strike-slip tectonics. Structures on non-tectonic origin and features involving gravity and salt tectonics are also explored in this topic.
