The Great Northern Peninsula of Western Newfoundland contains the Highlands, the largest external basement massif of the Grenville Orogeny in the Appalachian Orogen. This Precambrian basement is known as the Long Range Inlier, Long Range Complex or Basement Gneiss Complex, consisting of quartz-feldspar gneisses and granites that are up to 1,550 million years in age. The Long Range dikes are mafic in composition and have an age of about 605 million years.^[2]
