Patterns and estimates of post-Rupelian burial and erosion in the Campine area,north-eastern Belgium

We have compiled a dataset containing information on patterns of burial and erosion that occurred during the last ca. 30 Ma in the Campine area, north-eastern Belgium. This area coincides with the occurrence of the Rupelian Boom Clay which is considered as one of the potential host formations for radwaste disposal. Patterns and estimates of erosion and sedimentation, based on geological and geomorphological data, from several locations within the Boom Clay outcrop and subcrop zone, show increasing burial in northern and north-eastern direction over the last 30 Ma. More southern areas have experienced erosion and denudation during some geological stages, usually in the order of several 10 m, up to 100 m at most at two discrete locations. During the Quaternary, erosion is a widespread phenomenon in the Campine area, except in the Roer Valley Graben. The obtained estimates of erosion and burial are compared and discussed in the context of the overall geodynamic evolution of north-western Europe.
