Ancient cratonic nuclei in East Antarctica: Research status, problems and prospects
The Archean cratonic nuclei in the East Antarctic Shield (Craton) occur mainly in the Napier Mountains, southern Prince Charles Mountains, Rauer Group and Vestfold Hills in the Indian Ocean sector, and are sporadically exposed in the Australian, African and Pacific sectors. These ancient nuclei with...
