Petrography and geochemistry for mafic and ultramafic rocks from Tonagh Island in the Napier Complex, East Antarctica: A preliminary report

The geology of Tonagh Island is divided into five geological units. The boundaries among the units are thrusts or shear zones. Tonagh Island is dominated by mafic to felsic layered gneisses.
