About Aeschynite-(Y)Hide

Formula:
(Y,Ln,Ca,Th)(Ti,Nb)2(O,OH)6
Colour:
Pale yellow, yellow-orange, pale greenish yellow, black, brownishblack
Lustre:
Resinous, Waxy, Pearly, Sub-Metallic
Hardness:
5 - 6
Specific Gravity:
4.82 - 4.93
Crystal System:
Orthorhombic
Name:
For its relationship to Aeschynite-(Ce), with yttrium as the dominant rare-earth element. First named in 1906 as blomstrandine by Waldemar Christofer Brøgger, in honor of Christian Wilhelm Blomstrand [October 20, 1826 Växjö, Sweden – November 5, 1897 Lund, Sweden], professor of chemistry at the University of Lund, who did the chemical analysis. Brøgger had earlier published a crystallographic description of this material in 1879 from Urstad Feldspar Mine, Hidra, Vest-Agder, Norway but then without a chemical analysis. He first thought it to be identical with aeschynite (From Miask, which later was named aeschynite-(Ce)). Later, in his description in 1906 he states that the blomstrandine from Hitterö was a "Yttrium-Aeschynit".
The mineral was later renamed Aeschynite-(Y) by the IMA in 1987 following Levinson (1966).

The yttrium analogue of Aeschynite-(Ce).
The most common Aeschynite Group mineral.
