The bedrock of the Salo area in SW Finland is mainly occupied by granitoids. We dated five granitoids and two mafic volcanic rocks with single zircon method. The granitoids fall in two age groups, 1.86–1.85 and 1.83–1.82 Ga. Mafic plutonic rocks occur in both age groups. The volcanic rocks are 1.90 and 1.89 Ga in age. Further, the samples display two periods of metamorphic zircon growth at 1.86 and 1.83 Ga, synchronous with the granitoid magmatism.
