Description
Summary:Cape Ryugu, Oku-iwa Rock and Telen are located along the Prince Olav Coast and the Lutzow-Holm Bay region, East Antarctica, where crystalline basement rocks are found to occur extensively. Geological field observations in the three areas by the geologists of the 19th Japanese Antarctic Research Expedition in 1977-1978 are described, and the geological maps of the areas are presented. The basement rocks exposed in these areas are chiefly biotite gneiss, garnetbiotite gneiss, biotite-hornblende gneiss, and siliceous gneiss with subordinate amounts of metabasites, granite, pegmatite and aplite. The foliation plane of gneissosity or banded structure of the metamorphic rocks is monoclinal in general, while folding structures are observed in some places.
