摘要：
Two distinct mesozonal lithotectonic units are defined in Terre Adelie: a western metasedimentary migmatitic unit formed during a Palaeoproterozoic thermal and tectonic event, and an eastern meta-igneous unit, which underwent a longer evolution, starting during late Archean times. These units were tectonically joined between 1.7 and 1.5 Ga (basement cratonization). No Pan-African imprint was detected. The previous regional syntheses may be questioned as they assumed a major Late Archean granulite event and the extension of a Pan-African prograde metamorphic gradient.
