Most soils clearly belong to two different universa, and as a consequence there are two classification triangles, one for aeolean and one for the other sediments, with an overlap in the sand corner (Figs. 14 and 15, see also 'Bijlage' Ic).

This type of sandy clay was called "zavel" in Dutch and "sablon" in French. In the 14th century a small chapel in the sablon area was transformed into an important pilgrimage site where a miraculous statue of Our Lady was venerated.)
