The late-Proterozoic Allard Lake ilmenite deposit is located in the Havre-Saint-Pierre anorthosite complex, part of the allochtonous polycyclic belt of the Grenville Province. Presently the world's largest Fe–Ti oxide deposit, it had a pre-mining amount in excess of 200 Mt at grades over 60 wt.% hemo-ilmenite. The main ore body is a funnel …

The Lac Tio hemo-ilmenite ore body crops out in the outer portion of the 1.06 Ga Lac Allard anorthosite, a member of the Havre-Saint-Pierre anorthosite suite from the Grenville province of North America. It is made up of ilmenitite (commonly with more than 95% hemo-ilmenite) associated with noritic lithologies and anorthosite. The present study compares …

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 …

Ilmenite, otherwise called manaccanite, is a titanium-iron oxide mineral with formula: FeTiO3. It is a noteworthy wellspring of titanium. Typically thick and tabular, its crystals sometimes occur as thin lamellae (fine plates) or rhombohedra.. It can also be massive, or occur as scattered grains. Intergrowths with hematite or magnetite are ...
