锐钛矿

Electronmicroscopic examination shows that Ti-oxide (rutile or anatase) is replaced by brannerite, indicat-ing the metasomatic origin of brannerite.

在镜下观察到钛铀矿与钛的氧化（红或锐钛矿）成交代关系，说明钛铀矿是交代成因的。

The mineral assemplege of the deposit is composed of diaspore, kaolin, illite, chlorite, hematite, anatace and rutile with tourmaline, zircon, goyazite in less.
