A bi-partite Ferdynandovian succession from Lukow, Eastern Poland:a new palynostratigraphic approach

摘要

The paper presents a new approach to the Middle Pleistocene lacustrine deposits at the Lukow site (Lukow Plain, E Poland). The results of pollen analysis document a rarely found complete Ferdynandovian pollen succession with evidence of two warm periods of intergla-cial rank and two cold ones. New geological and palynological data are presented and interpreted against a background of earlier research by Ruhle and Sobolewska from 1969, including a comparison with the nearest complete Ferdynandovian succession at Zdany (Siedlce Upland) and with the stratotype section of Ferdynandow. The proposed division of the Lukow sequence into two warm periods separated by a succession typical of glacial periods has been based on a new division of Ferdynandovian pollen succession applied for the first time to the Podgorze B1 pollen profile. Two warm units and the intervening cold one in the Lukow pollen sequence correspond to the climatostratigraphical units Ferdynandovian 1 and 2 separated by the cooling/glaciation (Ferdynandovian 1/2) and can be related to the Cromerian Complex.
