The Deposits of the Useful Minerals and Rocks: their Origin, Form, and Content

Abstract

THE first volume of this treatise was reviewed in NATURE for January 28, 1915 (vol. xciv., p. 583). The second volume completes the work so far as ore-deposits are concerned. The third volume does not appear as yet to have been published in Germany. Ore-deposits are classified according to their mode of origin as follows: magmatic segregations, contact-deposits, lodes, and ore-beds. The first volume dealt with the first two of these groups and with tin-lodes and quicksilver deposits belonging to the third. The second volume deals with lodes of gold and silver; lead, silver, and zinc; uranium; antimony; iron; manganese; copper; pyrites and arsenopyrites; nickel and cobalt. It concludes with an account of those ores which occur as beds in sedimentary deposits. Each section is preceded by a bibliography.
