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.展开更多

Christite was discovered as a new mineral in 1977 in the Carlin-type gold deposits, Nevada, U. S. A. by A. Radtke et al. The christite discussed in this note occurs in a high-grade Tl ore deposit, Guizhou Province and has been reported for the second time in nature.展开更多
