Abstract The basement in the Pointe Geologie Archipelago, around the French Dumont D'Urville station in Terre Adelie, comprises a metapelitic migmatitic complex with a 1.7 Ga metamorphic evolution differing from that generally found in other areas of the East Antarctic Shield. In Terre Adelie, although the oldest crustal precursors (Nd T DM model ages) are ca. 2.2–2.4 Ga old, inherited zircon SHRIMP ages are ca. 1.73–1.76, 2.6 and 2.8 Ga. The migmatitic evolution is restricted to a single event… CONTINUE READING
