Excerpt: ... anorthosite of this Morin area exhibits a great variation in structure and colour and in certain places even a considerable variation in composition, but is in mineralogical composition a gabbro or norite free from olivine and very rich in plagioclase. Hand specimens from about fifty different places in the area have been sliced and microscopically examined, and the following description of these rocks is based on the results thus obtained. The number of minerals which the rock contains is not large, the variations in composition resulting principally from their irregular distribution. The following minerals have been observed in the rock: --Plagioclase Muscovite and Paragonite Epidote Augite Bastite Zoisite Hypersth ene Chlorite Garne t Ilmenite Quartz Zircon Orthoclase Magnetite Spinel Hornblende Apatite Biotite Calcite Of these plagioclase, augite, hypersthene and ilmenite are by far the most important. As above mentioned, Hunt adopted the name anorthosite for these rocks on account of the great preponderance in them of plagioclase or anorthose. He considered the type which contains only felspar as the true anorthosite and estimated that three-fourths of the anorthosites in the Dominion did not contain over five per cent of other ininerals. Like the other constituents of the rock, the plagioclase is quite fresh, showing but very rarely any traces of decomposition, and when it is not granulated (that is protoclastic or cataclastic in structure) presents in hand specimens, almost without exception, a dark violet, but more rarely a reddish colour. This colour is still plainly visible in thin sections, although naturally much fainter, and is seen to be caused by the presence of an immense quantity of minute opaque black rods and extremely..

Book excerpt: Excerpt from Report on the Geology of a Portion of the Laurentian Area: Lying to the North of the Island of Montreal In character and general aspect these rocks of the Hastings series are almost identical with many of those which in the Eastern Townships and in New Brunswick have been regarded as probably Huronian for many years; and so marked is the resemblance that the author, in presenting his summary report for 1894, referred the rocks seen near the Bristol iron mines to that division. It now appears very conclusively established that both in the eastern and western areas we have a well developed series of rocks, including limestones. Gneiss and schists, which are of undoubted sedimentary origin, but which have been enormously acted upon' by great intrusive masses as well as by other dynamic agencies, so that in many parts their original characters have almost entirely disappeared.
