A Study Of The Magmatic Sulfid Ores is a scientific book written by Cyrus Fisher Tolman Jr. and originally published in 1916. The book is a comprehensive study of the formation and characteristics of magmatic sulfide ores, which are a type of mineral deposit that forms from the cooling and solidification of magma. The book begins with an overview of the geology and mineralogy of magmatic sulfide ores, including their physical and chemical properties. It then delves into the processes of ore formation, including the role of magmatic fluids and the conditions that lead to the formation of specific types of sulfide deposits. The book also includes detailed case studies of several notable sulfide deposits, including the Sudbury nickel-copper deposits in Canada and the Noril'sk-Talnakh deposits in Russia. These case studies provide a deeper understanding of the complex geological processes involved in the formation of magmatic sulfide ores. Overall, A Study Of The Magmatic Sulfid Ores is a valuable resource for geologists, mining engineers, and anyone interested in the science of mineral deposits. It provides a thorough and detailed analysis of the formation and characteristics of magmatic sulfide ores, and is an important contribution to the field of economic geology.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
