- 論文の詳細を見る
Several islands of the west of Langhovde composed of seven main islands and their neighboring islets are situated at 69°08′-69°17′S latitude and 39°24′-39°36′E longitude. The basement rocks exposed in this region are classified as follows : (1) metabasite, (2) pyroxene gneiss, (3) garnet-biotite gneiss, (4) garnet gneiss, (5) leucocratic biotite gneiss, (6) pegmatite. The gneissic rocks have been subjected to granulite facies metamorphism and are correlated with the Ongul Group of the Lutzow-Holm Bay System. Their folding axes in this region trend northwest like those in the Langhovde region.
