Geology of the Sandercock Nunataks in Enderby Land, East Antarctica (Reports of the Japanese Antarctic Research Expedition)
The Sandercock. Nunataks (68°33'S, 52°07'E) are composed of several small nunataks which are tentatively named A, B, C and D. Nunatak "A" consists mainly of hornblende-biotite gneiss and Nunatak "B" of hypersthene-garnet gneiss and garnet gneiss. Nunatak "C" i...
