[SMP35-01] Re-examination of metamorphic and geochronologic events in eastern Dronning Maud Land and Enderby Land, East Antarctica: current status and future perspectives
Keywords:Antarctica, Gondwana, supercontinent, metamorphism, geochronology
Archaean and Proterozoic pre-Gondwana history is preserved in the Napier Complex and the Rayner Complex in Enderby Land with the earliest geologic history traced back to >3.8 Ga (e.g., Harley and Kelly, 2007). Western Rayner Complex located between Lützow-Holm Complex and Napier-Rayner Complexes is key for the linkage between Gondwana and pre-Gondwana areas. All these areas were experienced granulite-facies partly UHT metamorphism.
This study will present our current understainding of the metamorphic and geochronologic evolution of these areas and the recent geologic field survey at Lützow-Holm, Western Rayner, Rayner and Napier Complexes during 2016-2017, and also future perspectives.
