Tīmeklis2024. gada 31. marts · The Rb–Sr isochron age of quartz rhyolites coincides with the model age of primary U ores from the Vostok deposit (Golubev, 1991 unpub) and with the results of direct dating of the U ore process at the Shokpak deposit (Chernyshev et al., 1983), which is located beyond the BOC. Tīmeklis2024. gada 1. dec. · Most Rb resources of the deposit are hosted by the hydrothermal biotite in the veins and the related extensive biotite alteration zones, and Rb enrichment is accomplished by substituting for K in the biotite ( Han et al., 2024 ). These Rb ore bodies possesses an estimated reserve of 169000 t Rb 2 O.
