Hydrothermal vent complexes offshore Northeast Greenland: A potential role in driving the PETM
Continental rifting is often associated with voluminous magmatism and perturbations in the Earth's climate. In this study, we use 2D seismic data from the northeast Greenland margin to document two Paleogene-aged sill complexes ≥18 000 and ≥10 000 km2 in size. Intrusion of the sills resulted in...
