About Eucolite
Formula:
[N(1)N(2)N(3)N(4)N(5)]3[M(1.1)M(1.2)]3[M(2.1)M(2.2)M(2.3)]3-6[M(3)M(4)]Z3[Si24O72]Θ4X(1)X(2)
A variety of Eudialyte group (being optically negative).
First described as a new mineral by Scheerer (1847) from near Barkevik, Langesundsfjord, Vestfold, Norway. The name is dervived from the greek for "easily satisfied", because the mineral was more satisfied with more Fe instead of Zr, as opposed to wöhlerite:
Today it would probably be regarded as a variety of ferrokentbrooksite and not eudialyte s.s.
