- ‘Some of the characteristic minerals found in kimberlite are olivine, pyrope garnet, enstatite, diopside, ilmenite, phlogopite, perovskite, magnetite, and spinel.’
- ‘Small anhedral pyrope garnets and ilmenite can be collected from the shallow pit that remains.’
- ‘Titanium resides principally in heavy minerals: ilmenite, rutile, anatase and sphene, whereas Zr is located predominantly in zircon.’
- ‘Garnets form large idiomorphic and sub-idiomorphic grains; the majority contain inclusions of omphacite, ilmenite, rutile, zircon, apatite and quartz.’
- ‘The pegmatite is composed of microcline, plagioclase and quartz with minor amounts of clinopyroxene, orthopyroxene, ilmenite and zircon.’
Early 19th century: named after the Ilmen mountains in the Urals + -ite.
