Cechy osadów i rozwój sedymentacji w zagłębieniach bezodpływowych obszarów lessowych na przykładzie stanowiska Snopków (Płaskowyż Nałęczowski, wschodnia Polska)

Closed depressions are characteristic elements of the loess plateau landscape. They formed by suffosive processes occurring within initial depressions in the loess cover. Detailed study were conducted in the eastern part of the Nałęczów Plateau (Lublin Upland) in one of the closed depressions located near a multicultural archaeological site. In the closed depression the Holocene soil-sediment sequence of a total thickness 1,3 m were documented. The soil-sediment sequence filling the closed depression and its bottom-forming loesses were detailed physico-chemical and micromorphological analyses as well as C-14 dating performed. This allowed to determine of postglacial litho- and pedogenesis development in the closed depression. Four major phases of Holocene sedimentation were recognized, witch were correlated with human settlement activity from Neolithic to modern times.
