Plate Tectonics

17. Location of Archaean Napier Complex, East Antarctica
Antarctic Ice Sheet

18. Recent zircon SHRIMP U-Pb data from other
area of the Napier Complex
Locali*es of >3600 Ma~ inherited/protoliths
Locali*es of c.3000 Ma~ protoliths
Locali*es of c.3300 Ma~ protoliths

19. Typical lithologies at Mt. Riiser-Larsen
Grt-Qtz-Fsp gneiss
(grani*c gneiss)
Opx-Qtz-Fsp gneiss
(tonali*c gneiss)
Grt-Sil gneiss
(peli*c gneiss)
Magne*te-Qtz gneiss
(meta-BIF)
Sapphirine-Osumilite gneiss
(Mg-Al-rich metasediments)
Mostly anhydrous mineral assemblages !
- responsible for granulite (~UHT) metamorphic condiDons

Sapphirine+quartz from Napier Complex
by Dallwitz (1968)

which indicates metamorphic T >1000ºC
based on the experimental constraints
