Ilmenite deposits occur in anorthosite in the vicinity of Allard Lake, about 25 miles north of Havre St. Pierre (Quebec) on the north shore of the St. Lawrence River. Three main rock …

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-shaped …

The Grader layered intrusion is part of the Havre-Saint-Pierre anorthosite in the Grenville Province (Quebec, Canada). This intrusion has a basin-like morphology and contains significant resources of Fe–Ti–P in ilmenite and apatite.Outcropping lithologies are massive oxide alternating with anorthosite layers, banded ilmenite–apatite–plagioclase …

The area of Allard Lake lies immediately north of Havre St. Pierre and well known to have the most important occurrences of magnetite-ilmenite found in the region. The mineral occurrences of Allard Lake were first published by the Quebec Department of Mines. The results of the chemical analysis indicate an average content of 55% FeO and 35% TiO2.

An ilmenite-magnetite containing 32% or upwards of TiO2 is saleable. Deposits of pure ilmenite are not common, but deposits of very large size are now being mined at Allard lake, near the Gulf of St. Lawrence, 450 miles northeast of Quebec City. There are large quantities of the ilmenite- magnetite mixture in Quebec, Ontario, and …

Allard Lake, Quebec, Canada Haemoilmenite comprises an ilmenite host (pink-brown) with exsolution bodies of haematite parallel to (0001) of the host ilmenite. The larger haematite bodies themselves carry further ilmenite exsolution bodies (centre) and rutile laths (lilac-grey, oriented cast-west, centre right).

An 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 …

According to Rose Fulton Cramer's Wayne County Missouri, Hardy Allard was buried in Woodlawn Cemetery in Jefferson City. He may have been a widower with no family members nearby at the time of his death. The family in the 1830 U.S. Census of Wayne County included two males under age 5, one male 10-15, and another 30-40 …

The Chilka Lake igneous complex of Orissa, the largest known anortosite massif of the Indian Shield, occurs in a catazonal environment of high-grade metamorphics of the Eastern Ghats Precambrian Orogenic Province. The syntectonic massif consists of the anorthositic Balugaon dome, leuconoritic Rambha lobe and quartz-mangeritic Kallikota cover.

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 …

Although most ilmenite is recovered from breach-sands, an important quantity is mined from magmatic segregations in anorthosite complexes such as at Stillwater in Montana, U.S.A., Allard Lake in Canada and this example in Norway. Successful exploitation has depended on its location near a fjorded coastline close to the industrialized part of ...

[1] Hemo-ilmenite ores from Allard Lake, Quebec, were first studied over 50 years ago. Interest was renewed in these coarsely exsolved oxides, based on the theory of lamellar magnetism as an explanation for the high and stable natural remanent magnetizations (NRMs), 32 to 120 A/m, reported here.
