Summary. Laboratory seismic velocity measurements on rock samples from metamorphic terrains, coupled with geologic cross sections, provide the basis for synthetic seismic reflection profiles for various types of continental crust. Results from greenstone belts, mylonite zones and partial cross sections of continental crust indicate that lithologic heterogeneity and geometrical factors control crustal reflection characteristics.
