An up to 180 m-thick debris avalanche deposit related to Ferrar large igneous province magmatism is observed at central Allan Hills, Antarctica. This Jurassic debris avalanche deposit forms the lower part (member m₁) of the Mawson Formation and is overlain by thick volcaniclastic layers containing a...
