| Sumario: | In the eastern part of the Bahìa Ushuaia outcrops dark schists pertains to the Yaghàn Fm. of the Lower Cretaceous, strongly deformed by Upper Cretaceous Andean compresional tectonics. They are intruded by a basaltic rock with tholeitic-calc-alkaline affinity with a prevalent lithology of the pyroxenites and monzonites. The aereomagnetic survey and magnetic measurements of rocks samples, integrated with the geological informations permitted to model a N-S cross section through the area. |
