Resolving the age of the Haughton impact structure using coupled 40Ar/39Ar and U-Pb geochronology

Resolving the age of the Haughton impact structure using coupled 40Ar/39Ar and U-Pb geochronology

The Haughton Dome located on Devon Island, in the Canadian Archipelago represents a well-preserved, moderate-sized, complex impact crater. Previous age constraints for the 24 km-diameter impact structure have ranged from ca. 21 Ma to ca. 39 Ma. Herein, we present a coordinated microstructural and in...
