Catalogue of Canadian Minerals

Résumé du livre

"In the preparation of A Catalogue of Canadian Minerals, a search of literature dealing with Canadian minerals was made, and it became apparent as the compilation progressed that for many common minerals it would be impractical to attempt to record all reported localities of occurrence. An arbitrary list of common minerals was drawn up and occurrences of these were not recorded unless the reference contained either analytical data or some feature likely to be of particular interest, such as distinctive physical properties, unusual associated minerals or mode of occurrence, economic value, or use as a gemstone or decorative stone. Occurrences of hydrocarbons, rocks, coal, petroleum and natural gas were not compiled." --
