The mineralogy and mineral chemistry of low-grade rocks from the upper Pristley Glacier area are described to define the metamorphic zonation and P-T conditions of the Ross age metamorphism. Two metamorphic zones og increasing metamorphc grade have been distinguished: the ankerite and biotite zones. The metamorphic temperature ranges from 320 to 400 °C. The Ross metamorphism falls into the range of low-pressure metamorphism.

Abstract
The mineralogy and mineral chemistry of low-grade rocks from the upper Pristley Glacier area are described to define the metamorphic zonation and P-T conditions of the Ross age metamorphism. Two metamorphic zones og increasing metamorphc grade have been distinguished: the ankerite and biotite zones. The metamorphic temperature ranges from 320 to 400 °C. The Ross metamorphism falls into the range of low-pressure metamorphism.File in questo prodotto:
