Abstract

Whole-rocks of three granites and a gneiss from the Västervik area, south-eastern Sweden, have a Rb-Sr age of 1750 ± 50 million years: (late) Svecofennian. Age measurements on three separated biotites disclose the imprints of younger, probably Gothian events, but a discordance exists between the K-Ar and Rb-Sr ages: 1465 ± 30 and 1380 ± 50 million years, respectively. A pegmatite yielded a Rb-Sr whole-rock age of 1425 ± 50 million years.
