The Miocene stratigraphy of Belgium
|The classical nomenclature on the Miocene stratigraphy of Belgium has been made up by De Meuter & Laga (1976).
It is divided into the following units:
:: The Edegem, Kiel, Antwerpen and Deurne Members are present in the Antwerp area.
:: The Zonderschot, Genk, Houthalen and Dessel sands are found more to the east, in the Campine area and Limburg.
|However, after the publication of this stratigraphy, new units have been found, which have to be placed into this scheme :|
|The Breda Formation is found only in a boring near the Dutch border, the other deposits have been found in the Antwerp area or to the east, in the Campine area.
All these Miocene stratigraphic units have a rather uniform lithological outlook. They consist of black to greenish gray sands or claeyey sands with a large glauconite content, except the Heterocetus Sand and sandstone, Genk and Dessel sand, which have another color and are less glauconitic.
| Louwye (2000), Louwye et al. (1999,2000) studied dinoflagellate cysts of the classic stratigraphic units and succeeded in placing them in the international time scale. It appear that nearly the whole Miocene is present, but not in a continuous section, only as short intervals. Furthermore, the different Miocene Sands seem to be not synchronous in their whole range. |
The Antwerp and Zonderschot Sand Members are lateral equivalents.

|New faunistic and stratigraphic observations were presented by Marquet (1997, 1980, 1991, 1997, 1998), Marquet et al. (2002) and by Bosserlaers et al. (2004)|
