1937 A. L. Du Toit Our Wandering Continents iv. 62 A major geosyncline..traversing Bolivia, north and central Argentina, Cape, Weddell Sea, passing east of King Edward VII Land and through Edsel Ford land, crossing Tasmania and the eastern part of Australia to New Guinea... This feature, which seems to have played so vital a rôle during the evolution of Gondwana,..can conveniently be called the ‘Samfrau’ Geosyncline—a contraction of the words ‘South America—South Africa—Australia’.

1959 New Biol. 29 14 A further example of this type is the Samfrau geosyncline, of which Du Toit has suggested the remnants now occur in South America, South Africa, and Australia.

1971 M. H. P. Bott Interior of Earth vii. 202 Examples [of good fits of tectonic features on the assumption of continental drift] include..the fitting together of the Samfrau orogenic belt of Gondwanaland.
