Abstract
The Precambrian evolution of south-western Sweden is reviewed concisely to provide a background for the dating of the Varberg charnockite. It is shown that the alleged Gothian and western Pregothian regions pass continuously into each other. In the west, the oldest dated rocks have ages around 1700 Ma. An older (Svecokarelian?) basement may be present in the eastern parts of the region. Basic magmatism, metamorphism and the relationship between orogenic and anorogenic events are discussed.Keywords
