Extensional Fault Systems A- Evolutionary model illustrating progressive extension accommodated by block rotation above a low-angle extensional fault. B-Listric fault with hangingwall rollover anticline. Area and B are equal. C-Flat/ramp geometry of fault produces geometrically necessary folding in hangingwall
Force Force is a kind of mechanical action between different objects, it tends to change the shape, volume or movement state of the object with a force upon it. Force is a vector quantity, and thus possesses both magnitude and direction; it can be represented by an arrow whose length specifies the magnitude and whose
