Relative Role of Eustacy, Climate, and Tectonism in Continental Rocks
Relative Role of Eustasy, Climate, and Tectonism in Continental Rocks - The renaissance in stratigraphy over the last two decades has been largely driven by the belief that stratigraphic packaging is determined by allocyclic controls. An understanding of the controls on stratigraphy allows us to make better predictions

The Nuussuaq Basin of West Greenland is a Late Cretaceous-early Tertiary extensional basin, related to the opening of the Labrador Sea and Baffin Bay. An extensive Early Paleocene valley system was incised following a period of active faulting and uplift of the basin. The paleovalley system is exposed along the south coast of the Nuussuaq peninsula and includes five broadly synchronous valleys that embrace sandstones assigned to the Quikavsak Member. The valleys are 1-2 km wide and up to 190 m deep. The valleys were incised during a major relative sea-level fall and were cut into Cretaceous and earliest...
