11.05.2015· Among the three basic groups of rocks (i.e., magmatic, metamorphic and sedimentary), magmatic rocks (volcanic or extrusive and plutonic or intrusive) cover most part of the solid earth surface, in which the major Fe oxides are magnetite and ilmenite, and to a lesser extent, hematite 9,10.

Ilmenite is an opaque accessory mineral in a wide range of igneous and metamorphic rocks, especially gabbroic varieties, where it is associated with hematite and magnetite as lattice-type intergrowths, and other minerals such as plagioclase and hornblende. Masses of ilmenite were found in several emery mines in the USA, Norway, Canada and Russia. Its principal use is as an ore of titanium.

In SEM images these small hematite lamellae are shown to have ilmenite lamellae. Magnetite, rutile needles, discrete pyrite and pyrrhotite are also present in AL20c. A late stage alteration with magnetite replacing hematite is commonly associated with sulfides. Magnetite is present also as elongate plates replacing some hematite. These alterations and accessory phases are reported from ...

Ilmenite is a black mineral with a submetallic to metallic luster. With just a glance it can easily be confused with hematite and magnetite. The differentiation is easy. Hematite has a red streak, while ilmenite has a black streak. Magnetite is strongly magnetic, while ilmenite is not magnetic. Occasionally ilmenite is weakly magnetic, possibly ...
