Early Proterozoic U-Pb Zircon Ages from Basement Gneiss at the Solovetsky Archipelago, White Sea, Russia
ABSTRACT
The central region of the Neoarchaean Belomorian Mobile Belt (BMB) is, except for the Solovetsky Archipelago, largely covered by the White Sea. A newly discovered granitic gneiss outcrop on Solovetsky Island, Russia, enables a first age determination of the archipelago and evaluation of the hitherto poorly constrained central BMB. Zircons separated from the orthogneiss were analysed with SIMS-SHRIMP and LA-ICP-MS techniques. Both techniques yield a concordant U-Pb age of ca. 2.430 Ga, coinciding with ages of granitic intrusions in the BMB ca. 50 km west of the Solovetsky Islands.
