A new subdivision of crystalline Fennoscandian erratic pebble assemblages (Saalian) in the Central Netherlands

Abstract

The inland-ice cap in the Saalian in the central part of The Netherlands caused the formation of glacial basins and ice-pushed ridges and the deposition of till as well as glaciofluvial and glaciolacustrine material (Drente Formation). Crystalline assemblages of pebbles in these deposits, especially in till, are discussed and a new subdivision based on the Fennoscandian area of origin is introduced. The composition of the indicator pebbles made it possible to distinguish various deposition areas as the effect of one inland-ice cap.
