Web12.2 Folding. When a body of rock, especially sedimentary rock, is squeezed from the sides by tectonic forces, it is likely to fracture and/or become faulted if it is cold and brittle, or become folded if it is warm enough to behave in a plastic manner. The nomenclature and geometry of folds are summarized on Figure 12.5.

WebOct 17, 2024 · Reverse fault. A dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. This type of faulting is common in areas of compression, When the dip angle is shallow, a reverse fault is often described as a thrust fault. “Occurs where the “hanging wall” moves up or is thrust over the “foot wall””. Web4.2 Earthquakes Types of Faults. Faults are the places in the crust where brittle deformation occurs as two blocks of rocks move relative to one another. There are three major fault types: normal, reverse, and strike-slip. Normal and reverse faults display vertical, also known as dip-slip, motion.
