P(論文) A variety of Mg-rich silica-undersaturated aluminous gneisses containing sapphirine, spinel and corundum occur within the ultrahigh-temperature (UHT) metamorphic sequence at Tonagh Island in the Napier Complex, East Antarctica. They occur as blocks or pods in quartzo-feldspathic gneisses or ma...
