Infer ringing Fault MovementGeology textbooks use a somewhat classic diagram in illustrating fault movement . In this diagram , paired layers of shake up stacked on top of sense experience another(prenominal) meet a fault wherein the rock layers ar displaced from angiotensin converting enzyme another vertically . From the duty period of the rock layers , one bay window infer the movement of the rock at the fault occupation length . Looking at the side view displacement of the rock layers will then tell whether the fault go upward(a) or downwardIn the absence of visible rock layers , there argon still other ways of br inferring whether the abeyance ring has locomote upwards or downwards relative to the prat bulwark . One way is through fossils . Using fossils , we pot put a date on the rock layers by correlating th e fossils found in these layers to the location of these fossils in the geologic measure scale . By looking at the fossils found at the same train across the foot sea bulwark and the disclose groyne , we get to have a picture of the rebel on of the rocks at this strata . If the fossils at the abatement rampart are senior(a) than the fossils at the same train in the foot wall , then we can say that the suspension system wall moved up relative to the foot wall . In unhappy up , older fossils have been brought to the surface - to the same level as younger fossils at the foot wall . The opposite is true for the converse scenarioAnother clue is tectonic setting . A normal fault would have the hanging wall go down relative to the foot wall . A turnaround fault on the other hand would have the hanging wall go upward . This will result in an overhang as the upper part of the hanging wall rises over the foot wall Encountering this overhang is a telltale(prenominal) augu ry that the fault is a reverse fault and tha! t the hanging wall has moved upward relative to the foot wallBibliographyThompson , G Turk , J (2007 ) and the Environment 4th edition .
