This group was deposited during the early [[Paleocene]] [[epoch (geology)|epoch]] and is subdivided into two formations: the [[Houthem Formation]] (lower) and the [[Opglabbeek Formation]] (upper). The group is named after the region of [[Hesbaye]] in the south of [[Limburg (Belgium)|Limburg]].<br /> <br /> The Houthem Formation consists of shallow marine [[sand]]y [[limestone]]s of early to middle [[Danian]] age (about 65-63 million years old). It is found in the province of [[Limburg (Belgium)|Limburg]] and the north of the province of [[Antwerp (province)|Antwerp]]. This formation also occurs in the [[Netherlands]], where it is considered part of the [[Chalk Group]]. The Opglabbeek Formation is an alternation of continental to lagunary clay, sand and [[lignite]] layers of early [[Selandian]] age (about 60 million years old). This formation only occurs in the north and east of the province of Limburg. Corresponding deposits in the Netherlands are divided with the [[Landen Formation]].<br /> <br /> The Hesbaye Group lies stratigraphically on top of older, [[Cretaceous]] formations, such as the [[Maastricht Formation]] (sandy limestone). The late Paleocene [[Hannut Formation]] (marine clays, sands and limestones) is normally lying stratigraphically on top of the Hesbaye Group.<br /> <br /> ==References==<br /> *Laga, P.; Louwye, S. &amp; Geets, S.
