| Lithological description | The Zandvliet Member, introduced as a new member by De Meuter & Laga (1976), is as a fine-grained, glauconiferous and slightly clayey quartz sand. It is horizontally stratified and contains sandstones and siderite concretions. Characteristically and contrary to the other members of the Lillo Formation, it is decalcified and holds no shells or shell debris. |
| Age | No age information is available. |
| Thickness | Up to 15 m. Near the type section, a decrease in thickness results in an increased thickness of the underlying Merksem Member (Deckers et al., 2021). |
| Area of occurrence | Probably restricted to the northern part of the Port of Antwerp and nearby the villages of Zandvliet, Berendrecht and Stabroek. |
| Type locality | The type locality is the village Zandvliet, located north of Antwerp. The type section was in a temporary outcrop for the construction of the Zandvlietsluis north of the city of Antwerp (GSB 014E0153, 014E0154, 014E0155, 014E0156; DOV GEO-79/205-A, GEO-79/205-B, GEO-79/205-C, GEO-79/205-D; Figure 62 1). These were correlated with CPTs by Deckers et al. (2021; GEO-79/202-SIII; GEO-83/033-SXXXV; GEO-79/202-SVI; GEO-79/202-SVIII; see also Figure 62 2). Type geophysical borehole log is borehole Stabroek (GSB: 015W0216; DOV kb7d15w-B296) with the Zandvliet Member from 4 to 10 m depth (Figure 62 3). |
