    The sedimentary history of the upper Maastrichtian-Paleocene succession underneath the extensive Paleocene flood basalts in central West Greenland, supports models for the generation of flood basalt provinces in response to rising, hot mantle plumes. The rise of the North Atlantic mantle plume was associated with deposition of at least three sedimentary sequences; each associated with incision of submarine canyons and valleys. Relative sea-level changes were caused by plumerelated tectonics and generation of sequence boundaries was in general associated with catastrophic sedimentation and very rapid development of sequences. As such the late Maastrichtian-early Paleocene sequences record a spectacular and significant but rare geological event.
