Radiocarbon age of organogenic sediments in Lake Jasień subglacial channel and their paleogeographical significance

Florek W., Pazdur A.

Geochronometria

2000

Vol. 18

41-46

The dating of 26 deposit samples taken from the Lake Jasień subglacial channel and from its immediate vicinity made it possible to determine when the floor set of peat deposits, commonly occurring at the bottoms of lakes and peat bogs, was formed. Spatial and altitude differentiation of replacement time of the palustrine-peaty accumulation by the limnic accumulation gave a chance to settle the range of Lake Jasień reach changes and their chronology. Also the dating of peat layers in top parts of the organogenic sets filling the hollows neighbouring the lake served this purpose. The attempts to use the gyttja dating to solve the stratigraphic problems of investigated area have failed.
