Abstract
The isotopic–geochronological features of thorianite and baddeleyite from carbonatites of the Guli massif, located within Maimecha–Kotui province in the north of the Siberian Platform, are characterized for the first time. The economic complex platinum-group element (PGE) and gold placer deposits are closely related to the Guli massif. Similar geochronological data for thorianite (250.1 ± 2.9 Ma, MSWD = 0.09, n = 36) and baddeleyite (250.8 ± 1.2 Ma, MSWD = 0.2, n = 6) obtained by two different methods indicate that carbonatites were formed close to the Permian–Triassic boundary and are synchronous with tholeiitic flood basalts of the Siberian Platform.
