| Lithological description | The upper loesses are better preserved than lower loesses; they are spread all over Middle Belgium, reaching locally up to 15 m thickness on plateau. The sediments are either calcareous loess, in situ or reworked along the slopes, or decalcified. Several interstadial palaeosols are distributed through the whole formation. Several tundra gleys also occur as marker horizons. The upper part of the formation is affected by the pedogenesis of the Holocene Luvisoil. |
| Age | Covers the whole Upper Pleistocene with the exception of the Rocourt Pedocomplex (i.e. MIS 5a pro parte to MIS 2) (Haesaerts, 1974; Haesaerts et al., 1997; 1999; Frechen et al.,2001; Pirson et al., 2009). |
