Bąk, K., 1989. In the case of planation surfaces in the Białka drainge basin in the High Tatra Mountains (W sprawie poziomów zrównań w dorzeczu Białki w Tatrach Wysokich). Folia Geographica, Series Geographica-Physica, 21: 93-115.

Summary: Development of the preglacial relief of the Tatra Mountains remains continually an open question. The paper is a successive attempt of searching the problem, particularly on possibility of reconstruction of preglacial levels, which are conditioned by cyclic development in Neogene. Researches have been carried out in the Bialka drainage basin in the High Tatra Mts, on the area of nearly homogenous geologic structure. Correlation morphologic flatissements allows to distinguish 5 of valley levels as well as adequate ridge and slope levels. The average heights of these valley levels are: I: 2000-2080 m a.s.l., II: 1900-1980 m a.s.l., III: 1780-1820 m a.s.l., IV: 1580-1620 m a.s.l., V: 1140-1400 m a.s.l. These levels are fragments of part planation surfaces, which were glacially transformed during Quaternary. As a result of glacial erosion, the valley flatissements were lowered about 25-40 m in upper part of the drainage basin and in lower part - about 60-70 m. However, the magnitude is varied in particular valleys. Some of little flatissements have structural premises resulting from joint or fault fissures. Development of relief of the area could be influenced by neotectonic factors which were connected with older dislocation zones rejuvenation. The Dolina Pięciu Stawów Valley is a good example of tectonic retardation in development of relief accordingly to adjacent areas. Hence cyclic development of preglacial relief of the Tatra Mts, expressed by step-like partial planation surfaces which were formed during 5 successive fluvial-denudational cycles, have been disturbed as a result of differentiated neotectonic movements.
