Geological setting, composition and morphology of injective sandy bodies in Lower Permian deposits of the south part of Novaya Zemlya are described. Formation of these bodies is interpreted as a result of liquefaction of sandy beds and extrusion of the formed suspension into the host clayey sediments. This process was caused by high sedimentation rates in a prograding submarine fan environment fed with siliciclastics from the rising Urals orogene to the south of Novaya Zemlya.
