| 摘 要： | 本文对prismatine(Prs)名称的来历作了简要介绍,指出kornerupine(Krn)系列中一个四面体位置上的B含量可变化于0和1之间(在22(O,OH,F)的分子式中),并伴随成分、晶体结构及矿物组合的变化。以 B=0.5为界划分可出两种不同的矿物:若B<0.5,为Krnss,包括两种情形:B=0,为无B之Krnss,0

| Abstract: | A brief history of the name prismatine has been given in the paper. It is pointed out that the B content in one of the
tetrahedrals of kornerupine varies between 0 and 1 (per formula unit of 22 (O, OH, F) ), being accompanied by the changing
mineralogical properties such as composition, crystal structure and mineral association at its occurrence. Two distinct minerals are
defined by the critic of B = 0. 5, i. e., kornerupine sensu stricto (Krnss) if B < 0. 5, including the boron-free (B = 0) Krnss
end-member, and prismatine if B > 0. 5. Accordingly, the analogue (B = 0. 89) near Zhongshan Station of China at East Antarctica
is prismatine which is unique in its abundance and occurrence even in the world. The corresponding Chinese names of the minerals
are recommended. |
