Following the widespread trangression during the Upper Cretaceous with its peak in the late Campanian and early Maastrichtian, there followed over most of Northwest Europe a regional regression with the deposition of the late Maastrichtian and Danian ‘chalks’. Locally, here in South Limburg, the Upper Maastrichtian shows the characteristics of a transgressive sequence resulting from local downwarping along the major fault block area to the northwest. I wish to describe the features of this sequence as seen in the deposition of the Maastricht Chalk and Kunrade Chalk.
