Excerpt from A Microscopic Study of the Silver Ores and Their Associated Minerals: A Dissertation Submitted to the Department of Geology and Mining and to the Committee on Graduate Study of the Leland Standford Junior University in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy
The increasing amount of Space devoted by many of the jour nals to investigations in which the reflecting microscope is em ployed, is sufficient evidence of the great value of this new method of attack in the solution of problems of paragenesis of the opaque minerals. That these researches are confined so largely to the investigation of the copper sulphides and associated minerals is the occasion of some surprise. Although in a more or less gen eral way it has been appreciated that the replacements concerned in the process of co-pper enrichment are common phenomena of nature, yet the fact that these processes may, in their complexity and interest, 'be duplicated in the deposition of silver minerals, has failed to receive the emphasis it deserved. This is due in part to the greater scarcity of silver minerals and also to the greater difficulty involved in their identification. More-over, the applica tion of these methods to Copper deposits has 'been a significant factor in the solution of economic problems, and. Has thus acted as a stimulus for extended researches in those fields. This stage of development has not yet been realized for the silver ores.

Paperback. Condition: New. Print on Demand. This book takes a fascinating, microscopic look at silver ores and their associated minerals. The author, a pioneer in the field of microscopic mineral analysis, delves into the processes of ore deposition, revealing how these minerals are formed and interact with each other. The book traces the formation of silver minerals through a series of stages, from the earliest pyrite, sphalerite and arsenopyrite to later deposits like stromeyerite, pyrargyrite, proustite and native silver. It explores the role of various minerals, including copper, nickel and cobalt, in the complex interplay of chemical reactions and physical changes that create these precious ores. The author, drawing on a wealth of specimens and meticulous analysis, challenges assumptions about the origin of silver minerals, revealing the intricate processes of replacement and transformation that shape these deposits. The book's insights into the world of silver ore minerals offer a deeper understanding of how these valuable resources are created and shed light on the fascinating world of microscopic mineralogy.
