FER-1 was obtained from a bed of magnetite-quartz iron-formation at Austin Brook near Bathurst, New Brunswick. These minerals comprise 55% and 30%, respectively, of the volume of the sample. The hematite content is about 3%.
FER-2 is from an iron-formation bed occurring in greywacke at the north pit of the Griffith Mine at Bruce Lake, Ontario. Magnetite makes up about 25% of the sample by volume. Amphibole and quartz are the major gangue constituents.
FER-3 and FER-4 are from the Sherman Mine property at Temagami, Ontario. FER-3 is from the west pit in the north limb of the Tetapaga incline containing metavolcanic and pyroclastic rocks. Quartz is the most abundant mineral present. Hematite occurs as dusty inclusions in the quartz, but as micro-laminae in jasper layers. FER-4 was taken in the south pit from a cherty magnetite iron-formation containing chloritic tuff. The mineral assemblage of FER-4 is similar to that of FER-3, but the proportions of the minerals differ.
