Book Description
Excerpt from Descriptive Catalogue of a Collection of the Economic Minerals of Canada: And Notes of a Stratigraphical Collection of Rocks Native Iron. 1. Madoc, O ... Geological Survey. a. Native or meteoric iron. This aerolite was found in 1854, and before cutting weighed 370 pounds. It contains 6.35 per cent. of nickel, and in making a section of it, rounded masses of magnetic sulphide of iron (probably troilite) were observed. When etched with an acid it exhibits beautifully the so-called Widmannstattian figures. Several large masses of meteoric iron have been discovered in the North West Territory, but have not as yet been carefully examined. Magnetic Iron Ore. 1. Texada Island, B.C. ... Geological Survey. a. Specimens of magnetic iron ore. This important deposit occurs in crystalline rocks supposed to be of Carboniferous age. The largest exposure is on the south side of the island, about three miles north-west of Gillies' Bay. Here the ore-bed is seen to be from twenty to twenty-five feet thick, and to rest on grey crystalline limestone, with which, for about two feet down, are interstratined bands of ore, of from half an inch to one inch in thickness. From this point to the north-west, for nearly a mile, the bed is occasionally seen, and at one place there is a continuous exposure about 250 feet long and from one to ten feet thick. To the north-east it is also said to have been traced for more than three miles. As regards mining and shipment the ore is most favourably situated, while in the event of smelting operations being carried on, there is an abundance of wood suitable for making charcoal on the island, and Comox Harbor, from which the coal of the Comox area will be shipped, is less than twenty miles distant. The ore is of an iron-grey colour, and frequently contains little cavities, which hold red or yellow ochre. Sometimes the cavities are lined with octahedral crystals of magnetite. A partial analysis of a specimen collected by Mr. James Richardson, of the Geological Survey, gave 68.40 per cent. of iron and only .003 per cent. of phosphorus. The deposit is in part owned by Messrs. Nelson & Moody, of Burrard Inlet. - Carboniferous? 2. An Island in Queen Charlotte Sound, B.C. ... Captain Lewis, Victoria. a.Specimen of magnetic iron ore.
