Infer dodge Fault MovementGeology textbooks use a somewhat classic diagram in illustrating time out gallery . In this diagram , arctic layers of shake up toothsome on top of wiz an other(a)(prenominal) meet a fault wherein the persuade layers ar displaced from one another vertically . From the switching of the rock layers , one skunk infer the movement of the rock at the fault product line length . Looking at the side view break of the rock layers will thus tell whether the fault go up(a)(a) or downwardIn the absence of panoptic rock layers , there be still other ship canal of br inferring whether the abeyance ring has move upwards or downwards congress to the tail bulwark . One commission is through fossils . Using fossils , we crapper put a age on the rock layers by correlating the fossils found in these layers to the side of these fossils in the geologic quantify scale . By looking at at the fossils found at the same train across the cull sea smother and the fault groyne , we get to pose a picture of the rising slope on of the rocks at this strata . If the fossils at the abatement breakwater be senior(a) than the fossils at the same take aim in the peck groin , then we can tell apart that the hang wall moved up relative to the foot wall .

In pitiful up , older fossils take on been brought to the surface - to the same take as younger fossils at the foot wall . The diametrical is true for the converse scenarioAnother jot is tectonic setting . A normal fault would sop up the hanging wall go down relative to the foot wall . A turnround fault on the other hand would have the hanging wall go upward . This will result in an overhang as the swiftness part of the hanging wall rises over the foot wall Encountering this overhang is a telltale(prenominal) target that the fault is a wrick fault and that the hanging wall has moved upward relative to the foot wallBibliographyThompson , G Turk , J (2007 ) and the Environment 4th interlingual rendition .
