Abstract
The age of the Thunderstone granite, which is the pedestal of the Bronze Horseman monument to Peter the Great in Saint Petersburg, is dated at ~1595 Ma. This age was obtained by U-Pb dating of accessory zircon separated with a jewelry gravel from the biotite flakes. The study was carried out on a secondary ion microprobe SIMS SHRIMP-IIe at the Center of Isotopic Research of the Karpinsky Institution (Saint Petersburg). 15 local U-Pb isotopic analyses were performed on 12 zircon crystals. It is not yet possible to recognize the source of the Thunder Stone, since granites of the same age have not yet been found either in the Vyborg batholith (1665—1615 million years), or in the Salminsky batholith (1547—1535 million years), or in other granite intrusions located in the proximity of Saint Petersburg. Thus, the Thunder Stone seems to confirm the historically established idea about its uniqueness and hints that its homeland should be sought among the manifestations of the yet unidentified phases of Early Riphean granitoid magmatism in the nearest regions.
