Ieper Group
The Ieper Group is a group of rock strata in the subsurface of northwest Belgium. The group is subdivided into three marine formations, all formed during the Ypresian, a single age of the geologic timescale. Both age and group are named after the West-Flemish town of Ypres, for which the Dutch name is "Ieper".
The three formations of the Ieper Group are:
The Ieper Group lies stratigraphically on top of the Landen Group and below the Zenne Group. Unlike the Zenne Group, the Ieper Group can also occur in more southern parts of Belgium, for example in the Mons Basin.
