Nomenclature and classification of the basement metamorphic and plutonic rocks around the Lutzow-Holm Bay region, East Antarctica
The report discusses the usages and terminology of petrological terms used in the previous papers concerning the basement metamorphic and plutonic rocks around the Lutzow-Holm Bay region, East Antarctica. The terms are classified into the following categories : (1) Lithology (mainly based on chemica...
