Resumen
New K-Ar mineral dates from calc-alkaline granitoids of the Archipiélago Cabo de Hornos, in the southernmost tip of South America, range from 97 to 117 Ma. This confirms that the early Cretaceous was a period of major plutonic activity in the region and expands previous radiometric information on the Patagonian Batholith concerning migration of intrusion foci with time.
