Document Summary
Stress - force applied per unit area. Folds are features formed by plastic deformation. Faults are features formed by brittle deformation permanently deforms by breaking. Strike - horizontal line (intersecting of rock layer with a horizontal plane) in plane. Circular folds : folding about a central point. Basins - circular fold in which rock layers dip toward central point of point of folding folding. Anticlines - linear fold in which rock layers dip away from axis of horizontal layers folding. Synclines - linear fold in which rock layers dip toward the axis of folding. Hanging wall goes down relative to footwall. Hanging wall goes up relative to footwall. Special type of reverse fault called thrust fault a low angle reverse fault (dip of the fault place less than 20 degrees) - rocks are displaced large horizontal distance along a vertical fault. Left lateral or right lateral - rocks across fault appear to have surface is nearly vertical moved which way.
