Occasionally in this bed, some boulders of solid ore were noticed, the largest being two feet in diameter. Little stringers of pure white fine sand were occasionally seen in the pyrites, but apart from these minor occurrences, the pyritic sand seemed to be a pure concentrate. It is said that on the surface this deposit first made...

All are found well developed at the Helen mine, and all but the griinerite schist have been found in the Lake Eleanor iron range also, while granular silica and siderite occur in large quantities in every important part of the range, though small outcrops sometimes show the silica alone. All of the rocks of the iron formation contain considerable amounts of iron pyrites. The grained silica and the granular silica is similar in certain respects to the jaspers and ferruginous cherts of...

Little stringers of pure white fine sand were occasionally seen in the pyrites, but apart from these minor occurrences, the pyritic sand seemed to be a pure concentrate. It is said that on the surface this deposit first made its appearance as a chimney* of sand about thirty feet in diameter, and that as followed down the siliceous sand was gradually replaced by pyritic sand until the present level was reached, and that the pyritic sand has been replaced in the bottom...
Page 67 - The principal areas of iron formation possibly bearing iron ore are at Gros Cap, Sayers and Boyer lakes, just east of the Helen mine, around Brooks Lake, south of Long Lake, just east of Goetz Lake, in Parks Lake, and between Parks and Kimball lakes. The Upper Huronian rocks are represented principally by the Dore...
Page 15 - ... while in case their mother-rock can be shown to have been quartz porphyry they are usually called schistose porphyries. In their extreme development these two types are often petrographically indistinguishable and they present an instructive instance of the production of identical results by the action of the same physical forces upon matter of the same average composition, though differing widely in origin and its structure.1 The schistose porphyries occurring at Upper...
