The depositional environments of the Maastricht and Kunrade Chalks (Maastrichtian) from the type area of Limburg, Netherlands

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.
