独居石

A soft silvery metallic element; a rare earth of the lanthanide series; it occurs in gadolinite and monazite and xenotime.

一种软质的银色稀土属金属元素，见于硅铍钇矿、独居石和磷钇矿中。

Tin, gold, ilmenite, zircon, monazite and kaolin, fire-resistant clay, and so have the potential for exploration.

锡、金、钛铁矿、锆英石、独居石及高岭土、耐火粘土等具有找矿潜力。

Cerium is one of the most abundant rare earth elements in both bastnasite and monazite.

铈元素在氟碳铈矿和独居石矿中天然丰度很高。

The monazite samples of various genetic types are taken fro m different localities in China and have been analysed by EPMA.

采用电子探针分析研究了花岗岩、伟晶岩和热液交代等三种不同成因的独居石微粒微区成分分布的特征。

According to U-Pb dating on xenotime and monazite, the mineralization took place during 112 to 97 Ma and last for at least 16 million years.

磷钇矿和独居石的U-Pb定年结果表明，成矿年代为112~97Ma，成矿作用可能持续了16Ma以上。

A gray lustrous metallic element of the rare earth group; is used in special alloys; occurs in monazite and bastnasite.

一种有光泽的灰色金属元素，稀土属，用于特殊合金中，见于氟碳锑矿或独居石中。

A soft yellowish-white trivalent metallic element of the rare earth group; can be recovered from bastnasite or monazite by an ion-exchange process.
