In cases where the sedimentation rate exceeds the uplift rate, growth strata are typically characterized as sequences, bounded by two or more seismic reflections, that thin toward the structural high. Growth strata are generally folded in one or more limbs of the structure. In this seismic section, growth strata thin onto the fold crest, with the lowermost growth units exhibiting the greatest thickness changes. (2-D seismic data, reprinted from Shaw et al., 1997).
