Lemuel Jhon S Libres Janice Putian Sta Fe Lopez If your pocket gets empty your faults will be many FAULT FAULT FAULT FAULT FAULT A fracture along which there has been displacement of the sides relative to one another. Regional Strain. Types of Fault and the Principal Stresses. Fault Rocks. Gouge: non-cohesive, fine grained. Breccia: coarse angular fragments. Cataclasite: cohesive fragments. Fault Melt (pseudotachylite):. Chapter 6. Folding. Faulting. The buckling of a rock layer that was once horizontal. Buckles or folds appear on the landscape.. The main type of folds are:. Anticlines. Synclines. Faulting is the result of the movement of the earths plates. Faults occur where there is stress along a weak point in the earths crust.. What is a Fold?. A fold is a bent rock layer or series of layers that were originally horizontal and subsequently deformed.. Due to compression forces.. They are most visible in rocks that have layers.. Folding. When Earth’s crust bends, folds occur. Folding occurs under compression when forces act towards each other, such as when plates collide. . Folding & Faulting. Definitions. Compression. and Folds. The illustration shows an east-west cross section between the Allegheny Structural Front and North Fork Mountain. The topographic feature called Germany Valley sits atop the geologic structure called the Wills Mountain Anticline. Westward directed compressive forces associated with the . Folding. When Earth’s crust bends, folds occur. Folding occurs under compression when forces act towards each other, such as when plates collide. . Folding & Faulting. Definitions. Compression. Mr Boland . Geography. The earths crust is divided into layers. But because the earths plates are convergent, neutral and divergent the layers of the earths crust have been changed and deformed.. The three types of deformation are. Lemuel Jhon S. Libres. Janice Putian. Sta. Fe Lopez. If your pocket gets empty your faults will be many.. FAULT. FAULT. FAULT. FAULT. FAULT. A fracture along which there has been displacement of the sides relative to one another.. Faults form in rocks when the stresses overcome the internal strength of the rock resulting in a fracture. A fault can be defined as the displacement of once connected blocks of rock along a fault plane. This can occur in any direction with the blocks moving away from each other. Faults occur from both tensional and compressional forces. Lecture 11 – Brittle faulting. Geol 244 – structural geology. Lecture 11 – Brittle faulting. Types of Faults – Anderson’s theory.

LED BY PROFESSOR DONNY HUTTON The North Cornwall/Bude coastal section contains probably the best exposed, most accessible and spectacular fold structures seen in western Europe.

There are three types of stress: .
