Ilmenite is found in igneous and metamorphic rocks although it very rarely forms a major component of a rock.

What type of rock is ilmenite?

Ilmenite is a common accessory mineral found in metamorphic and igneous rocks. It is found in large concentrations in layered intrusions where it forms as part of a cumulate layer within the silicate stratigraphy of the intrusion.

Is titanium a igneous rock?

Most of the world's titanium is produced by mining heavy mineral sands. These sands occur down-gradient from exposed masses of igneous rock such as gabbro, norite, and anorthosite. These rocks contain titanium-bearing minerals such as ilmenite, anatase, brookite, leucoxene, perovskite, rutile, and sphene.
