Abstract

Considerable areas of south Poland are covered by loesses (Jahn 1950, 1956;Maruszczak 1972b, 1980; Jersak 1973). The content of carbonates in the mineralcomposition of these deposits varies from a few to over ten percent.The purpose of this paper was to determine the role of precipitation waters indecalcification of carbonate loesses on the example of the upper Sanna catchment area.Leaching of loess-like deposits is not discussed in this paper.
