Geochemical and Sr-Nd isotopic study of charnockites and related rocks in the northern Prince Charles Mountains, east Antarctica: Implications for charnockite petrogenesis and Proterozoic crustal evolution

Charnockite plutons were intruded into Meso-Neoproterozoic (similar to 1000 Ma) high-grade metamorphic zone in the northern Prince Charles Mountains (PCM), East Antarctica, immediately after peak granulite metamorphism in the region. Detailed geochemical and Sr-Nd isotopic studies were carried out o...

Description
Summary:Charnockite plutons were intruded into Meso-Neoproterozoic (similar to 1000 Ma) high-grade metamorphic zone in the northern Prince Charles Mountains (PCM), East Antarctica, immediately after peak granulite metamorphism in the region. Detailed geochemical and Sr-Nd isotopic studies were carried out on these plutons and related rocks, which enables important constraints to be placed on the regional tectonic setting as well as the origin of igneous charnockites.
