Heavy minerals, grain size distribution, and ice-rafted debris in the Greenland Sea during 44 to 30 Ma
The widely accepted age estimate for the onset of glaciation in the Northern Hemisphere ranges between 2 and 15 million years ago (Ma). However, recent studies indicate the date for glacial onset may be significantly older. We report the presence of ice-rafted debris (IRD) in ~44 to 30 Ma sediments...
