摘要
Summarized in this paper is authors work on electron microprobe studies of platinum group minerals in China since 1964. Of the studied minerals, quite a number are new platinum group minerals discovered for the first time in the world. Those discovered for the first time in China fall into seven broad groups, including 253 varieties as revealed by electron microprobe analysis. L.S. Birks's method was adopted in electron probe quantitative analysis and correction.The authors suggest that it is appropriate to use the correction coefficients compiled by L.S.Birks in 1963 to quantitatively correct electron microprobe data on platinum group minerals.
