Magnetic phases in hemo&ilmenite: Insight from low

temperature of hematite in the Allard Lake sample shows that the Morin transition is absent. This can be explained by the presenceoftitanium in the hematite structure since as little as 1% Ti4+ can suppress the Morin transition below 10 K[Ericsson et al.,1986]. The magnetic hyperfinefield in the hemo-ilmenite sample is about 1–2%less than that of

Origin of the giant Allard Lake ilmenite ore deposit

Jun 01, 2010 1.. IntroductionAn ilmenite deposit (50.67°N, 63.67°W) was discovered in June 1946 in the Allard Lake area near a small lake named Lac Tio during the first aeromagnetic survey for ore exploration (Bourret, 1949).It is located 43 km northeast of Havre-Saint-Pierre in Quebec.Following two years of intensive drilling by Kennco Explorations, it has been continuously exploited since 1951 as an

Haematite has a canted antiferromagnetic structure with a Néel temperature, T N = 675°C ().The sublattice spins lie within the basal plane but are rotated by a small angle about [001], producing a weak parasitic magnetic moment perpendicular to the alignment of the spins (Dzyaloshinsky 1958).End-member ilmenite has an antiferromagnetic structure with spins parallel to [001] and a Néel
