Abstract

The fossiliferous glacio-marine sequence of the “Pecten conglomerate” (=Low Head Member of the Polonez Cove Formation) of King George Island contains numerous pelecypod shells ofChlamys anderssoni (Hennig), which sometimes form lumachelles. These allochthonous coquinas, often with intraclasts, can be interpreted as storm deposits (tempestites). Their mode of distribution in the deposits of the Low Head Member suggests that sedimentation of this sequence was episodically interrupted by storm-generated energy events resulting in resedimentation of the biota assemblages.
