Nowe stanowiska laminowanych osadów jeziornych na Pojezierzu Kaszubskim

摘要: New sites of laminated lake sediments in Kashubian Lakeland. A b s t r a c . Annually are very valuable source paleoecological information because they provide precise timescale calendar years and limited post-depositional disturbances. They formed specific conditions that enable not only the formation but also preservation lamination, hence rarely occur. The goal was to find lakes with annually Lakeland which can new high-resolution paleoenvironmental paleoclimatic data for this part Europe. Based on statistical analyses including catchment geology topography, morphometric basin features hydrological parameters, pre-selection 22 water depths ranging from 15 35 m carried out. Gravity cores (30–90 cm long) were obtained 18 these during field survey 2006. split lengthwise, photographed digitally examined carefully. Four studied show distinct alternations pale dark laminae. For three (Kramsko Duze, Kramsko Male Borowo Wielkie) such laminations restricted sections only. Lake Suminko deemed most promising site its covering entire taken core. In all cases, biochemical varves developed spring/summer layers composed autochthonous carbonates fall/winter made organic detritus minerogenic particles.
