Abbreviation HNE
Parent unit
Child unit Pommeroeul Greensand Formation, Harchies Formation, Catillon Formation, Barquegnies Formation, Bernissart Calcuridites Formation
Lithological description Detriticfacies, more or less conglomeratic and glauconitic, with a siliceousopalinecement or with a carbonate cement, occasionally sandy, or highly glauconitic, sometimes marly, with many sponges (body fossils, spicules, cement with chalcedony, “spongolites”..). In this group all the lithological units formerly described as “meules” are assembled, from bottom to top:
– Pommeroeul Fm.: conglomerates and sands;
– Harchies Fm.: mainly conglomerates;
– Catillon Fm.: marls and sands;
– Bracquegnies Fm.: glauconitic conglomerates;
– Bernissart Fm.: granular limestones
Age The fossil assemblages indicate a Middle Albian to Early Cenomanian age.
Thickness May reach 150 m in subsiding zones of the western Mons Basin (Harchies).
Area of occurrence The western part of the Mons Basin. In the eastern part the Group is represented by facies with sands and glauconitic gravel with a chalcedony cement (“gaizes”). This Group is mainly known in abandoned mine shafts and boreholes.
Type locality The Harchies pit exposes most of the Group (Marlière, 1939).
