Quartair profile type card sheet 21 Tielt

This map shows the Quartaire profile types on the map sheet. The map shows the sequence of most recent deposits. These deposits are aeolian, fluviatile, tidal or slope deposits. The planes of the quaternary map represent the zones where similar successions of specific quaternary layers (profile types) occur. The thickness of the various constituent layers of a profile type must be indicated in particular by the additional isohypse and isopache maps and the additional texts. Quaternary deposits in Flanders are laterally and vertically heterogeneous and vary greatly in thickness.
