The role of the ?Serie Porfirítica? as basement is known, as a consequence of the regional extension of the quartz porphyries in Patagonia. This would be a restricted concept of the word basement. Besides this aspect, it is of interest to note the leptometamorphic rocks seen on the coastal area of the Parque Nacional Tierra del Fuego (Tierra del Fuego National Park) and neighbouring areas. They could be regarded as the basement of the Mesozoic marine column.
