Lithostratigraphy
Diest Formation
Rock name
Diestian ferruginious sandstone
Rock synonyms
bergsteen; ferruginious sandstone
Additional information
These deposits are assigned to the Diest Formation, but this has recently been questioned (Houthuys, 2014). In some cases, silex pieces are present in the stones. This variety is called 'Puddingstone of Ronse' or 'Poudinge de Renaix'
