Infer gloriole Fault MovementGeology textbooks use a somewhat classic plat in illustrating fault movement . In this diagram , paired layers of shake up stacked on top of virtuoso(prenominal) another(prenominal) meet a fault wherein the rock layers ar displaced from superstar another vertically . From the switch of the rock layers , one mountain infer the movement of the rock at the fault strain 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 are still other ways of br inferring whether the abeyance ring has move upwards or downwards relative to the diffuse bulwark . One way is through fossils . Using fossils , we toilet put a date on the rock layers by correlating the fossils found in these lay ers to the location of these fossils in the geologic time scale . By looking at the fossils found at the same train across the foot sea beleaguer and the hanging bulwark , we get to have a picture of the mount on of the rocks at this strata . If the fossils at the abatement border are senior(a) than the fossils at the same level in the foot wall , then we can say that the hanging wall moved up relative to the foot wall .

In bereft up , older fossils have been brought to the surface - to the same level as younger fossils at the foot wall . The diametrical is true for the converse scenarioAnother clue is tectonic setting . A normal fault would h! ave the hanging wall go down relative to the foot wall . A throwback 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) attribute that the fault is a reverse fault and that the hanging wall has moved upward relative to the foot wallBibliographyThompson , G Turk , J (2007 ) and the Environment 4th edition .
