Abstract
In the two-dimensional discrete element modeling of displacement of sedimentary layers caused by faulting within the basement, we attempted to move a rigid basement as if it were an elastic basement by controlling its motion through application of dislocation solutions. An advantage of our modeling procedure is that we can discuss displacement fields of sedimentary layers in connection with fault parameters. We simulated displacement fields of the sedimentary layers by means of our modeling procedure and found that our simulated fields are different from the fields obtained in rigid basement models and are dependent on the selected fault parameters.
