About AeschyniteHide

Name:

From the Greek αισχύνη ("aeschyne") for "shame", alluding to the fact that early chemists had difficulty with separations of titanium from zirconium in some samples.

Synonym of:

Aeschynite-(Ce), Aeschynite-(Nd), Aeschynite-(Y), Nioboaeschynite-(Ce), Nioboaeschynite-(Y), Tantalaeschynite-(Y)

A group of rare-earth, titanium, rarely niobium and tantalum oxide-hydroxide minerals. Localities listed are for undifferentiated members of the group.
The most commmon members are Aeschynite-(Ce) and Aeschynite-(Y).
