Ilmenite - chemeurope

Distinguishing features . Ilmenite is often recognised in many altered igneous rocks (which is most, to some extent) by the production of the white pseudo-mineral leucoxene.Often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimed ilmenite.
