The Strand Fiord Formation is a Late Cretaceous volcanic component, located on northwestern and west-central Axel Heiberg Island, Nunavut, Canada. The formation contains flood basalts which are found on western Axel Heiberg Island at Dragon Cliff 300m (1,000feet) tall.
The Strand Fiord Formation contains columnar jointing units that are usually 1to in diameter. The formation is interpreted to represent the cratonward extension of the Alpha Ridge, a volcanic ridge that was active during the formation of the Amerasia Basin.[2] The Strand Fiord Formation is also part of the High Arctic Large Igneous Province.
