| Abbreviation | VdWi |
| Parent unit | Veldhoven Formation |
| Child units | |
| Lithological description | The Wintelre Member predominantly consists of grey-green to dark green clay, alternating with clayey sand. |
| Age | No datation is available in Belgium. The age is possibly still Chattian but certainly ranging into the Aquitanian. |
| Thickness | The thickness of the Wintelre Member is 66 m in borehole Molenbeersel, according to Table 1 in Dusar & Vandenberghe, 2020 (cf. Matthijs et al., 2016). The member is absent outside the Roer Valley Graben. |
| Area of occurrence | The Wintelre Member does not crop out, and appears to be only recorded in the subsurface north of the Grote-Brogel – Heerlerheide faults. |
| Type locality | The reference section in the Dutch well Veldhoven-1 (NAM-RGD, 1980, p. 51, encl. 32) in Veldhoven can be used as a stratotype: Wintelre Clay Member (interval 935 – 1047 m). [TNO-GDN (2022), http://www.dinoloket.nl/veldhoven-formation-nmvf]. Belgian parastratotype: borehole Molenbeersel; GeoDoc 049W0226, ground level +33 m; Lambert coordinates x 247660, y 207752, Wintelre Member: 774 – 840 m below ground level. |
| Alternative names | Veldhoven Member: Veldhoven Clay Member was the original name of this unit but subsequently became the name of the entire formation. In order to avoid confusion the name of the member was modified into Wintelre (de Lang, 2003). |
