Mg-Al skarn of the Skallevikhalsen on the east coast of Lutzow-Holm Bay, East Antarctica
P(論文) The genesis of skarns that accompany crystalline marbles in the Skallevikhalsen region on the east coast of Lutzow-Holm Bay, East Antarctica, is discussed on the basis of the mode of occurrence and mineral paragenesis. The marbles in question are usually accompanied by distinctly zoned nodules...
