Quaternary mapping

The assignment is to prepare a quaternary map of an area in Flanders that corresponds to a topographic map on a scale of 1/50.000. The quaternary deposits are represented by means of a profile type map on which both the lateral distribution and the vertical upbuilding of the quaternary deposits is shown. By representing also the vertical variations of the facies a 3D view is indeed created. To make this aspect possible on basis of a 2D, in fact a sheet of paper can only represent two dimensions, a number of vertical profiles are introduced which are then a reflection of the different geological sequences found in the area. These vertical profiles are named special profiles types.
