... occurred at 311 ± 12 and 261 ± 3 Ma. Whole rock geochemical data suggest the Yangzhuang rhyolite (YR) and the felsic tuff members of the underlying Tarbagatay Group are the sources of Be and U. The Sr and Nd isotope data suggest the first stage of Be mineralization formed from Yangzhuang rhyolite-derived...
