Report On The Building And Ornamental Stones Of Canada Vol 1 Classic Reprint PDF Download

Excerpt from Report on the Building and Ornamental Stones of Canada, 1917, Vol. 5: Province of British Columbia All quarries which have produced structural stone in commercial quan tity were visited, and in addition, a number of others which have been worked for crushed stone, lime-making, etc. It was thought advisable to include quarries of this type in order to ascertain if they offer any encourage ment from the present point of view. The information thus gained is chiefly of a negative character, but it has been included in the report, as practically any sort of stone is of possible value as building material. Quarries of building stone in the narrower sense are those which are oper ated solely or primarily for the production of structural stone; it is thought that all such quarries are included in the report. While most of the quarries operated for other purposes were visited, the report does not pretend to be complete in this respect. In addition to actual quarries, a large number of outcrops were examined, to which attention was drawn by the existing literature on the subject, or by information obtained from private sources. It is manifest that considerable discretion had to be used in selecting the localities of this type to be visited, as some of the reported occurrences are too remote or inaccessible to make a visit possible in the time available for the investigation. In accordance with the plan followed in the earlier volumes of this report, a geological basis of classification has been adopted, although it is freely admitted that this method is less satisfactory in the case of British Columbia. The reason for this lies in the great number of formations, and in the lack of definite correlation of the formations of different districts. A strict adherence to the geological method of classification, or an attempt to present the subject to the satisfaction of the purely scientific reader, would obscure the economic essentials under a mass of detail quite foreign to the purpose of this report. In the chapter dealing with the geology of the province, certain geological tables are used: these are intentionally incomplete, and are not intended for the use of scientists, but merely to give the average reader a rough idea of the position in the time-scale of certain strata capable of yielding building stone.
