Quartair profile type map map sheet 33 Sint-Truiden

This map gives an image of the common Quartaire profile types on the map sheet. The map shows the sequence of most recent deposits. These deposits are aeolian, fluvial, tidal deposits or slope deposits. The planes of the quartar map represent the zones where similar successions of specific quartar layers (profile types) occur. On the thickness of the various constituent layers of a profile type, the additional isohypsen and isopacin maps and the additional texts should give indications. The quartar deposits in Flanders are lateral and vertically heterogeneous and vary greatly in thickness.
