Thermochronology data from Pearya Terrane, Ellesmere Island, North Canadian Margin ...
Thermochronology data suggest Eocene high-latitude rapid exhumation and topography formation. Enhanced exhumation of northern Ellesmere Island occurred ~67-59 Ma, ~55-48 Ma, 44-38 Ma, and 34-26 Ma. These exhumation periods largely correlate with changes of spreading rates and movement directions of...
