Evidence of Glaciation at the Eocene-Oligocene Boundary From Greenland

Evidence for Eocene–Oligocene glaciation in the landscape of the East Greenland margin Authors: Bernard et al Abstract: Assessing the onset and extent of Northern Hemisphere glaciation is required to understand Cenozoic climate change and its impact on topography. While the onset of accelerated Cenozoic erosion is generally associated with the Quaternary at mid-latitudes, some high-latitude passive margins may have undergone earlier glaciation starting at 38–30 Ma or even 45 Ma.
