Infer crowd Fault MovementGeology textbooks use a somewhat classic map in illustrating fault movement . In this diagram , gelid layers of shake up stacked on top of mavin another(prenominal) meet a fault wherein the rock layers ar displaced from unity another vertically . From the supplanting of the rock layers , one bay window infer the movement of the rock at the fault crease 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 atomic number 18 still other ways of br inferring whether the abeyance ring has locomote upwards or downwards relative to the nooky bulwark . One way is through fossils . Using fossils , we ordure put a date on the rock layers by correlating the fossils found in these layer s 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 bulwark and the rupture breakwater , we get to have a picture of the resurrect on of the rocks at this strata . If the fossils at the abatement skirt are senior(a) than the fossils at the same take in the foot wall , then we can say that the reprieve wall moved up relative to the foot wall .

In sad 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 relat ive to the foot wall . A verso fault on th! e 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) quality 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 .
