Scientific paper

Many features of wide-angle reflection data have been attributed to finely-layered structure in the lower crust. Reflections with similar character, however, can be produced by small-amplitude 2-D random velocity variations. Finite-difference seismograms for a lower crustal model with isotropic random velocity variations match field data recorded at the Black Forest, Germany. At source-receiver offsets beyond about twice the target depth, waves scattered from a random zone produce the appearance of horizontal layering in wide-angle data. Lower crustal reflectivity patterns can thus be explained by models that have lateral and vertical random fluctuations rather than fine-scale layering.
