| Lithological description | Thick pale yellow calcareous loess, finely laminated (Gullentops, 1954; Haesaerts & Van Vliet, 1974; Paepe & Vanhoorne, 1976). These sediments bear several tundra gleys. The bottom part of the member frequently show a deflation surface. Locally, a strong erosion phase is recorded, linked to the melting of the thick tundra gley ending the Vellereille Member (Harveng Soil). In the upper part of the member, the “Hesbayan loess” contains the Eltville Tephra (Haesaerts et al., 1981; Juvigné & Semmel, 1981; Meijs et al., 1983; Pouclet & Juvigné, 2009). |
| Age | Upper Pleistocene – lower part of Weichselian upper pleniglacial (lower part of MIS 2). |
| Thickness | |
| Area of occurrence | Middle Belgium, on plateau and slopes. |

Paratype: Harmignies (Omya Benelux and CBR chalk quarries; respectively at 50°25’08”N / 4°00’35”E and 50°25’13”N / 4°00’56”E);- Rocourt (ancient Gritten sand pit; 50°40’07”N / 5°33’45” E). |
