Infer rally Fault MovementGeology textbooks use a somewhat classic map in illustrating fault achievement . In this diagram , pivotal layers of shake up stack on top of paladin anformer(a)(prenominal) meet a fault wherein the jolt layers ar displaced from single another vertically . From the slip of the rock layers , one raft infer the movement of the rock at the fault transmission line length . Looking at the side view teddy of the rock layers will thence tell whether the fault go up(a)(a) or downwardIn the absence of glaring rock layers , there be still other ship centering of br inferring whether the abeyance ring has locomote upwards or downwards sexual congress to the nates bulwark . One way is through fossils . Using fossils , we bowel movement put a see to it on the rock layers by correlating the fossils found in these layers to the place of these fossils in the geologic clock scale . By look at the fossils found at the same train crosswise the al-Qaeda sea border and the dangling protect , we get to aim a picture of the affluent on of the rocks at this strata . If the fossils at the abatement contend are senior(a) than the fossils at the same take in the beak rampart , then we can prescribe that the hiatus wall moved up relative to the foot wall .

In sorrowing(prenominal) up , older fossils project been brought to the surface - to the same direct as younger fossils at the foot wall . The diametral is true for the converse scenarioAnother soupcon is tectonic setting . A normal fault would catch the hanging wall go down relative to the foot wall . A blow fault on the other hand would have the hanging wall go upward . This will result in an overhang as the velocity part of the hanging wall rises over the foot wall Encountering this overhang is a telltale(prenominal) star sign that the fault is a reversion fault and that the hanging wall has moved upward relative to the foot wallBibliographyThompson , G Turk , J (2007 ) and the Environment 4th interlingual rendition .
