摘要
This paper describes in detail the method of separating Rb and Sr from black shale samples by using cation exchange resin 71-616×20, experimental conditions, and the procedure of preparing samples for Rb-Sr isotopic analysis by mass-spectrometry. Reported in this paper are also several groups of Rb-Sr isochron dates.
