The geocomplex of closed depressions near Zduńska Wola
Languages of publication
Basic surface features of the Łask Interfluve near Zduńska Wola originated during the
Wartanian ice-sheet areal deglaciation. The ice-sheet waning resulted in formation of groups
of crevasse landforms such as kame plateaux, kame hillocks, kame terraces and melt-out
The post-Wartanian morphogenesis increased diversity of the relief by rejuvenation of
most of buried valleys, by cutting new valleys and raising the interfluve surface with aeolian
sheets and dunes. Sand and silt were deposited in melt-out depressions. The depressions had
initially functioned as closed depressions and had formed a local base level. They were
incorporated into a valley network presumably at the end of the Vistulian glaciation.
Blocks of dead ice melted gradually and it has led to the formation of flattenings in the
melt-out depressions bottoms. The flattenings are 2-3 m high and have short gentle slopes.
These slopes and the slopes of the melt-out depressions are cut with dells and basin-like
valleys. Few of the cuttings continue their direction as barely perceptible, shallow flat-floored
valleys drained by perennial or intermittent watercourses.
In the Holocene eight types of geocomplexes with stable matter and energy structure were
formed, as a result od natural processes. Man's influence has led to diversification of the
environment which can be represented by 19 types of present-day geocomplexes. The 19 types
are characteristic of all the melt-out depressions in the environs of Zduńska Wola, but they
display a unique mosaic in each depression. It is noteworthy that the depressions function as
groups of homolithic geocomplexes. Man-made changes in the depressions result from
agricultural land use
Artykuł przedstawia typologię i funkcjonowanie geokompleksów zagłębień wytopiskowych
na tle rozwoju paleogeograficznego zachodniego fragmentu Wysoczyzny Laskiej w okolicach
Zduńskiej Woli. Uwzględniono w nim naturalne procesy przyrodnicze i antropizację środowiska
związaną z użytkowaniem rolniczym.
