The Kaczawa sector of the marginal escarpment of the Sudetes Mts is 80-120 m high and separates upland denudation surfaces, probably Late Miocene in age, and flat foreland surfaces underlain by Cainozoic sediments. Genetically the scarp is related to the course of the Sudetic Marginal Fault. Scarp dissection by short, deeply incised valleys was the response to the Pliocene-Early Quaternary uplift of the Sudetes Mts relative to their foreland. Evidence for tectonic activity during the Late Quaternary is equivocal. Deformations of terrace levels have not been recorded whilst upper valley slope benches apparently cut off at the mountain front do not bear an alluvial cover.
