- 論文の詳細を見る
Metabasites in the Cape Omega area, the westernmost part of the Prince Olav Coast, are classified into two types, I and II. Type I contains clinopyroxene and Type II does not. Bulk chemical compositions of both types are characterized by the abundance in alkalies, especially (Na)_2O. The presence or absence of clinopyroxene is controlled by the bulk chemical composition, especially by the mole ratio of CaO/(FeO^*+MgO+MnO). Hornblende in Type I is characterized by the abundance of Si and (Al)^<VI> and poverty of Ti and K compared with that in Type II. The petrological and mineralogical characteristics of metabasites of the region from the Prince Olav Coast to Lutzow-Holm Bay show a systematic change, suggesting that the region has undergone westward progressive metamorphism.
