Chemical characteristics of fluorine-bearing biotite of early Paleozoic plutonic rocks from the Sor Rondane Mountains, East Antarctica
The chemical compositions of biotite grains have been determined for early Paleozoic plutonic rocks from the Sør Rondane Mountains, East Antarctica. The plutonic rocks are divided into three groups of the type-I granitoids, type-II granitoids and the Mefjell Plutonic Complex. Two types of biotite ar...

The chemical compositions of biotite grains have been determined for early Paleozoic plutonic rocks from the Sør Rondane Mountains, East Antarctica. The plutonic rocks are divided into three groups of the type-I granitoids, type-II granitoids and the Mefjell Plutonic Complex. Two types of biotite are found in the groups: pale yellow to dark green biotite in the type-I granitoids and brown to dark brown biotite in the type-II granitoids and the Mefjell Plutonic Complex. Mineral chemically, biotites from the type-I granitoids have higher SiO2 contents, F contents, and XMg values with lower TiO2 and Cl contents relative to biotites from the type-II granitoids.
