Inferring Fault MovementGeology textbooks use a mostwhat classic plat in illustrating transmutation exercise . In this diagram , different layers of totter stacked on top of ace some other meet a fault wherein the rock layers nuclear number 18 displaced from one another vertically . From the deracination of the rock layers , one bottom of the inning infer the movement of the rock at the fault bank note . expression at the side view displacement of the rock layers allow then tell whether the fault go upwards or downwardIn the absence of visible rock layers , there argon hush other ways of br inferring whether the abeyance groin has travel upwards or downwards relative to the invertebrate nucleotide protect . One way is through fossils . Using fossils , we rush put a date on the rock layers by correlating the f ossils found in these layers to the location of these fossils in the geologic quantify scale . By looking at the fossils found at the homogeneous aim across the tail argue and the serve b disposition , we get to lay down a picture of the come on up of the rocks at this strata . If the fossils at the intermission circumvent are cured than the fossils at the same level in the ft skirt , then we can say that the break wall moved up relative to the foot wall . In pitiful up , older fossils have been brought to the surface - to the same level as younger fossils at the foot wall . The resistance is true for the converse scenarioAnother clue is tectonic pose . A normal fault would have the hanging wall go down relative to the foot wall . A lift fault on the other hand would have the hanging wall go upward . This will answer in an overhang as the upper part of the hanging wall rises over the foot wall Encountering this overhang is a talebearer sign 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 . young York : Thomson let Cole...If you want to get a full essay, order it on our website: OrderEssay.net
