Page 72 - ... coming into the main valley at a right angle on its north side. The main valley was seen continuing north-westward some twenty miles beyond this point. Above the portage the valley varies from a quarter of a mile to a mile in width, and as the grade is heavy, the river rushes through it as an almost continuous heavy rapid, which does not freeze over. Only a narrow margin of ice was found along the shore, and over it travel was slow and difficult. " Where the main stream issues from the...
Page 59 - Iby rusty gneiss, the whole cut iby frequent intrusions of syenite and diorite. . . At the Portage du Fort village, there is a great development of the crystalline series, the intrusions being particularly well seen, and their action upon the limestone being marked by their alteration of this rock into marble. From certain beds of this locality the marbles employed in the interior of the Houses of Parliament in Ottawa were obtained
Page 15 - ... diorites and ashyweathering agglomerates. Near the south end, at the narrowest point, a dark series of cherty rocks follows the west shore and passes away to the south-west, followed again at the bend by beds of dark, fine-grained, thin-bedded rocks, of which some are thoroughly filled with iron pyrites and magnetite. Medicine rock, just out of water in the centre of the channel, is apparently a mass of ore, while the weathered pyrites supplies the Indians with " medicine." In the river at the...
Page 12 - Shallow lake, but strata which most resemble the typical rocks of this series are found on Gull Rock lake, and are seen to be only highly altered beds in contact with the Laurentian, which when followed along the strike, away from the contact, change very materially and resume the general aspect of the rest of the Huronian. The contact with the gneissic rocks and granites of the region was found to be generally of a brecciated character, the gneisses and granites while in a plastic condition surrounding...
Page 7 - The tar sands evidence an upwelling of petroleum to the surface unequalled elsewhere in the world, but the more volatile and valuable constituents of the oil have long since disappeared, and the rocks from which it issued are probably exhausted, as the flow has ceased.
Page 59 - ... on the southern side of the river, are mostly crystalline limestones of Laurentian age, cut by numerous dykes and masses of reddish syenite and diorite. A band of crystalline dolomitic limestone, with mica, chlorite and hornblende-schists, also cut by diorites, crosses the river in the vicinity of Arnprior and has a breadth westward of several miles. These are a portion of the
Page 60 - The Roche Fendue channel, on the south aide of Calumet Island, is very rocky, broken by numerous heavy rapids and chutes. The rocks are limestone, underlaid by rusty gray gneiss, but the syenitic and dioritic intrusions are frequent and masses of the limestone are often caught in the intrusive rocks. The rock on the north side of the Ottawa, between Bryson and the foot of Allumette island, is .mostly syenite. Occasionally small bands of limestone and gneiss are seen, but their area is small as compared...
Page 84 - On account of its toughness and durability, this white anorthosite pavino stone from New Glasgow has been extensively used for paving stones in the city of Montreal, especially on streets where there is a heavy traffic. A number of small quarries have been opened in the vicinity of New Glasgow, while a larger one is operated about two miles to the north of the village. The stone is blasted out in large blocks and is then dressed to the required size by means of large hammers. The industry which has...
Page 12 - Lauren tian gneisses of the region to the south-east has not been clearly determined. Huronian The series of schists, limestones and bedded materials originally of volcanic origin, here mapped as Huronian, in many respects lithologically resemble the larger areas to the south which have been designated by the local name Keewatin; but the presence of dark-blue limestone and of conglomerates with jasper pebbles, both very similar to those of the typical Huronian area north of Lake Huron, renders the...
Page 50 - A. lake limestones are the only sediments met with, and on the southern and north-eastern aides, highly siticiovw red and white sandstones (which become locally quartzites), take the place of the limestone under the trap. These sandstones lie directly upon the Archaean gneiss, and seem to be littoral beds, which mark the shore limit, in this direction, of the basin in the deeper part of which the limestones were deposited. .... Some of the sandstones,Hmestones, etc.,, about the lake would afford...
