Iron-bearing Olenite

A variety of Olenite
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Na,Ca)(Al,Fe)3Al6(Si6O18)(BO3)3O3O
Colour:
Pale blue
A Fe-bearing "variety" of olenite. This material contains significant amounts of Fe at the Y site, and significant amounts of [4]Al (~0.4 apfu) instead of [4]B in the T site. Further, the O1 site (W site) is only or mainly occupied by O and not by OH. Thus, strictly speaking, this mineral is an Fe-bearing "oxy-olenite" (compare also darrellhenryite, which is chemically similar, but contains essential Li).

Originally described from Kuklík pegmatite, Kuklík, Central Bohemia Region, Bohemia (Böhmen; Boehmen), Czech Republic.
