samarskite

Samarsky-Bykhovets himself was not involved in the studies of samarskite and samarium.

The chemical element samarium was first isolated from a specimen of samarskite in 1879.

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

Yttrium is also found in samarskite and fergusonite.

Samarskite occurs in rare earth bearing granite pegmatites with other rare minerals.

During the analysis of the mineral samarskite he concluded that it does contain an element similar to niobium and tantalum.

Other minerals include samarskite and fergusonite.

The newly chosen name samarskite merely acknowledged the role of Samarsky-Bykhovets in granting access to the mineral samples.

Decipium was the proposed name for a new chemical element isolated by Marc Delafontaine from the mineral samarskite.

The mineral samarskite (samarskite-Y, samarskite-Yb and calciosamarskite), and chemical element samarium are named after him.

Also in 1879, the new element samarium was isolated by Paul Émile Lecoq de Boisbaudran from the mineral samarskite.

Samarium was named after samarskite which was named for the Russian mine official, Colonel Vasili Samarsky-Bykhovets (1803-1870).

Well-known minerals containing yttrium include gadolinite, xenotime, samarskite, euxenite, fergusonite, yttrotantalite, yttrotungstite, yttrofluorite (a variety of fluorite), thalenite, yttrialite.

In 1874, Per Teodor Cleve concluded that didymium was in fact two elements, and in 1879, Lecoq de Boisbaudran isolated a new earth, samarium, from didymium obtained from the mineral samarskite.

Further spectroscopic analysis between 1886 and 1901 of samaria, yttria, and samarskite by William Crookes, Lecoq de Boisbaudran and Eugène-Anatole Demarçay yielded several new spectroscopic lines that indicated the existence of an unknown element.
