The petrography and structure of three small areas, the Nussbaum Riegel and the north and south sides of the Garwood Valley in the “Dry Valleys” region of Victoria Land, Antarctica, are described and discussed. The rocks are mostly pure or impure marbles plus lesser quantities of amphibolite, schist and quartz‐feldspar rocks, and mineral assemblages indicate that they have been metamorphosed under conditions of the amphibolite fades, and possibly, locally under conditions transitional to the granulite facies. In general they have not suffered retrograde metamorphism.
