Economic mineral deposits / Экономика месторождений полезных ископаемых

The first edition of this book appeared at the end of 1942. Since that time war and post-war readjustment has forcibly demonstrated the extent to which the materials of the mineral kingdom constitute the backbone of industrial life and peace-time economic development of nations. Former bountiful supplies now show serious depletion, and nations of the world are looking farther and farther afield for those miiieral supplies necessary to their subsistence. This book deals with' such mineral deposits, how they are formed, what they are, how and where they occur, and what they are used for. Its chief purpose is as a textbook, designed both for elementary and more advanced courses. The first edition was in demand also as a source of information to all those interested in mineral deposits and in the mineral industry. <...>
