BackgroundThe Adare Peninsula is a complex of overlapping shield volcanoes forming the northernmost volcanic pile of the Hallet Volcanic Province. Hamilton (1972) considered uneroded cinder cones at Cape McCormick to be of Holocene age, but similar-looking Antarctic cones have proved to be as old as Tertiary. Most Potassium-Argon dates for the Adare Peninsula range from 6-13 million years ago (Ma), but one possibly anomalous date of 1.14 Ma was obtained, and a sample from Cape Roget was dated at 2.27 Ma (LeMasurier and Thomson, 1990).
