Abstract

All the significant preservable geologic features of the modern East African rift system and the preceding Karroo graben system are matched in the western margin of Australia. The match holds over three orders of magnitude, from the length of the systems (measured in 10³ km) to the width of individual grabens (50 km). In both regions, triple junctions are a dominant tectonic element and are spaced about 700 km apart. Interrift regions, such as Lake Victoria, are probably destined to become marginal plateaus after continental breakup.
