Abstract

On the basis of analysis of the deposit forming the bottom of the Czyzowka river valley near Chrapanow on Sandomierz upland, the A. calls attention to significance of human activity in the transforming of the relief of the valley bottom. Above the fossil soil dated in the bottom at 11 000 380 B.P. and in the top at 5140 120 B.P., the A. found fragments of pottery from the late Middle Ages. It follows that the over six-meters thick series of the decalcified loessy silts covering the pottery has been accumulated for the last ca 500 years. These data from the Czyzowka valley as to the accumulation rate of valley deposits in modern times considerably exceed the corresponding values reported for the nearby Middle Vistula river valley or for the Subcarpathian river valleys. The A. discusses the effects of man's economic interference in environment on the vertical accretion of the alluvia and attempts to find the reasons for the peculiar intensity of that process.
