| Abstract: | The presence of the metamorphic high-pressure/low-temperature mineral association of lawsonite-sodic amphibole is reported at Cape Smith on Smith Island, located in the southwestern end of the South Shetland Archipelago. This association confirms the existence of a high-pressure/low-temperature metamorphic belt along the Pacific margin of the Antarctic Peninsula. This belt is considered to be the meridional prolongation of the metamorphic belt of similar metamorphic conditions known along portions of the Pacific margin of South America. |
