Attempt of lithostratigraphic correlation of tills in northeastern Poland and southern Lithuania

Stanisław Lisicki

Abstract


Six boreholes have been completed in the Polish-Lithuanian borderland. Samples of tills were collected to petrographic analysis of gravels 5-10 mm in diameter. Petrographic characteristics of tills were compared with lithotypes from central part of the Mazury Lakeland and the Augustów Lowland. Stratigraphic position of tills has been defined and then, the results were recalculated with application of the Lithuanian petrographic method. Comparative study indicated that there is no stratigraphic correlation between tills in southern Lithuania and northeastern Poland.
