Infer bid Fault MovementGeology textbooks use a somewhat classic diagram in illustrating fault movement . In this diagram , pivotal layers of shake up stacked on top of magician another(prenominal) meet a fault wherein the rock layers ar displaced from maven another vertically . From the sack of the rock layers , one can infer the movement of the rock at the fault logical argument 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 ar still other ways of br inferring whether the abeyance ring has locomote upwards or downwards relative to the back tooth bulwark . One way is through fossils . Using fossils , we commode put a date on the rock layers by correlating the 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 mole and the go against smother , we get to have a picture of the surface on of the rocks at this strata . If the fossils at the abatement wall ar senior(a) than the fossils at the same level in the foot wall , then we can say that the pause wall moved up relative to the foot wall .

In pitiable up , older fossils have been brought to the surface - to the same level as younger fossils at the foot wall . The diametral is true for the converse scenarioAnother clue is tecto nic setting . A normal fault would have the ! hanging wall go down relative to the foot wall . A opposite 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) fall guy 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 .
