Zusammenfassung:<正> U-series isotopic tracing is one of the important techniques for investigation of magmatic process. In the natural 238U radioactive series, 238U and 234U are isotopes not fractionated during the partial melting and fractionation crystallization. That is to say, the radioactive ratio (234U/238U) will keep being unity in both
