The Economic Aspect Of Geology Classic Reprint PDF Download

Excerpt from Economic Geology: With Special Reference to the United States The continued advance in our knowledge of Economic Geology has necessitated considerable revision for the new edition. In addition, the author has, at the request of a number of teachers, included a description of the more important Canadian mineral deposits, as well as brief references to some of the well-known ones of other countries. While these additions to the text and illustrations have increased the size of the book somewhat, the number of pages is not to be taken as a gauge of the actual increase in size, for the reason that over one hundred full-page illustrations, formerly bound as inserts, are paged in with the text in the present edition. The latest available statistics have been included, and unless otherwise stated are taken from the United States Geological Survey, and Canadian Department of Mines reports. In a few cases, investigations to which reference might have been made in the text have appeared too late to include them, but it has still been possible to insert them in the reference list, and this has been done.
