Quaternary terraces of the Zelivka River

BALATKA, B., KALVODA, J. (2010): Quaternary terraces of the Zelivka River. Geografie, 115, No. 2, pp. 113-130. - This article presents the results of a geomorphological analysis of localities of Quaternary river terraces along the Zelivka River and its historical-genetic interpretation in light of the formation of the Sazava terrace system. In addition, the morphogenetic characteristics of the Zelivka Valley are presented and the fluvial sediments and terrace system of its river are described, including a chronostratigraphic correlation with other river terraces of the Bohemian Massif. Situational data concerning the Neogene sediments and Quarternary terraces of the Zelivka River, including correlation with the Sazava River's terrace system, are presented in Table 1. In accordance with current Quaternary stratigraphic classification, the entire system of terraces along both the Zelivka and Sazava Rivers corresponds mainly with the Middle and Late Pleistocene, since the Cromerian Complex up to the Weichsel periods. The erosion phase previous to the accumulation of the first terrace in the Zelivka and Sazava valleys belongs to the end of the Early Pleistocene. Older levels of fluvial sediments in the studied area, which are situated in a higher morphological position and which had previously been classified as Pliocene, have, therefore, been stratigraphically shifted into the Early Pleistocene.
