The formation contains [[flood basalt]]s which are found on western Axel Heiberg Island at [[Dragon Cliff]] {{convert|300|m||abbr=on}} tall.
The Strand Fiord Formation contains columnar jointing units that are usually {{convert|1|to|3|m|ft|0|abbr=on}} 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]].<ref>{{cite journal | last1=Ricketts | first1=B. | last2=Osadetz | first2=K.
