gadolinite

The mineral that Gadolin examined was named gadolinite in 1800.

However, gadolinite does not contain more than trace amounts of gadolinium.

A rare earth metal, it is found in the minerals monazite and gadolinite.

Polycrase, or an allied species, was seen implanted upon the gadolinite.

Some of these have a rare-earth composition similar to that found in xenotime or gadolinite.

Ironically, as noted above, the mineral gadolinite actually contains only traces of Gd.

This is a mineral similar to gadolinite, uranotantalum (now called "samarskite").

Similar compositions are found in xenotime or gadolinite.

The minerals in question are gadolinite and xenotime, sources of the so-called rare-earth elements.

They also found rhenium in gadolinite and molybdenite.

It is found associated with gadolinite.

Ytterbium is found in minerals named gadolinite, monazite, and xenotime.

It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.

Allanite and gadolinite are examples of pyrognomic minerals.

Niven was looking for the mineral gadolinite, which was used as a street lamp filament.

In particular, thulium occurs in the mineral gadolinite.

It does occur combined with other elements in gadolinite, monazite, and other rare-earth minerals.

The first such mineral discovered was gadolinite, a compound of cerium, yttrium, iron, silicon and other elements.

In 1788 the mineral ytterbite (now gadolinite ) was discovered near the Swedish village (not town) of Ytterby.

It is named for John Baringer, who discovered in it large amounts of gadolinite about 1887 (Hess).

Gadolinite and euxenite are quite abundant and are future sources of yttrium sub group rare earths.

It is commonly associated with zircon, monazite, gadolinite, fergusonite, uraninite, yttrialite and pyrochlore.

Of the 47 minerals discovered at Barringer Hill, gadolinite, a radioactive form of yttria, triggered the most interest at the time.

Lars Fredrik Nilson and his team detected this element in the minerals euxenite and gadolinite.

Anders Gustav Ekeberg isolated beryllium from the gadolinite but failed to recognize other elements which the ore contained.
