Abstract (in english)
   The method which correlates tills on the base of petrographic coeffiecients, used for tills from Polish Lowland, cannot be directly applied in the Sudetic Foreland. Petrographic analysis of tills has several limitations in this area. Many crystalline rocks from Fennoscandia and from bedrock of the Polish Lowland and the Baltic Sea are very similar to the rocks of Sudety Mts. and Sudetic Foreland. Moreover, gravels deposited by Sudetic rivers many kilometres to the north from mountain range have been also redeposited by Ice Sheets. A content of local Sudetic or Carpathian material in glacial deposits reached 70%. Poorly rounded quartz grains from local crystalline rocks and well-rounded grains from Palaeozoic Sedimentary rocks predominate in local material. There are also rocks that are very difficult or even impossible to classify to one of the groups (local or Scandinavian).
   Scandinavian material consists less then 10% of Mezopleistocene alluvial gravel and if it will be not correctly identified the deposits could be classified as Eopleistocene or Pliocene. Correct determination ofprovenance of gravel material is very important for petrographic analysis of till and alluvial deposits in Sudetic Foreland. Only such an analysis which take into account differentation of local rocks gives us a possibility for lithostratigraphic correlation
