Ilmenite is an economically important and interesting mineral. It is named for its place of discovery (such places are called type localities) at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called"magmatic segregation".

Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.

Rob Hargraves worked on hemo-ilmenites from the Allard Lake area, Quebec for his Ph.D. thesis in 1959 and returned with great interest to these samples in relation to the concept of lamellar magnetism. Because the hemo-ilmenite ores produce large negative magnetic anomalies that can only be modeled with a significant remanent component, they are good analogs for the newly discovered Martian ...

Layers of apatite, magnetite, and ilmenite-rich gabbro also occur in the Sept Iles intrusion in Quebec (Namur et al., 2010, 2012). Other ilmenite-rich deposits may be essentially massive oxides (e.g., the Big Island massive hemo-ilmenite dike that crosscuts the Allard Lake anorthosite) and their origins are controversial (see below).

1. Introduction [2] The hemo‐ilmenite ores from the Allard Lake area, Quebec, have been of interest for their magnetic properties since the 1950s [Hargraves, 1959a; Carmichael, 1961].Nearly 50 years later, Hargraves' interest was rekindled in these rocks with the discovery of magnetic anomalies on Mars and with the concept of lamellar magnetism [Robinson et al., 2002, 2004].
