Crustal structure of the Innuitian region of Arctic Canada and Greenland from gravity modelling: Implications for the Palaeogene Eurekan orogen

Abstract

New gravity observations collected over Ellesmere Island and Axel Heiberg Island have been integrated with existing Canadian and Danish data sets to produce a comprehensive regional compilation over the Innuitian Region of the Canadian and Greenland High Arctic. This compilation has provided quantitative assessment of the geometry of the plate boundary between northern Greenland and Ellesmere Island and crustal structures across the Cretaceous-Palaeogene Eurekan Orogen. A large amplitude linear gravity low - Nares Strait Gravity Low (NSGL) (
