The results of the Soviet geological mapping program in the Prince Charles Mountains (Australian Antarctic Territory) are presented as the first major publication of the Soviet mapping program from 1983 and 1991. Except for a map of Else Platform, the maps published in this paper represent all maps completed by the 28th to 35th Soviet Antarctic Expeditions in the Prince Charles Mountains. The maps cover four suggested tectonic provinces, the Beaver Belt, Lambert Province, Fisher Belt and Ruker Terrane. The four terranes show a continuous increase in metamorphic grade from south to north. The Ruker Terrane is of a greenschist and lower amphibolite facies metamorphic grade, the Lambert Province consists of retrogressively metamorphosed Beaver Belt granulite and prograde metamorphosed greenschist of the Ruker Terrane and the Beaver Belt consists of high grade granulite. The Fisher Belt is a greenstone belt which is interpreted to be thrust later against the Lambert Province. Rock‐types of all four terranes as shown on the maps are discussed and an up‐to‐date summary of the work completed by the Soviet Antarctic Expeditions in the Prince Charles Mountains is given.
