The Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book’s empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors’ field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages. Presents the first book to galvanize lode gold research into a single authoritative reference Simplifies the complexity of lode gold’s underlying processes and presents valid concepts surrounding the lode gold forming environment Features color figures, illustrations, and photos that enrich the content’s focus and aid in the retention of key concepts

"You have heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents. What about its previous iterations, Rodinia or Columbia? These "supercontinents" from Earth's past provide evidence that continents repeatedly join and divorce. Scientists debate exactly what that next supercontinent will look like (and what to name it), but they agree that one is coming. In this book, Ross Mitchell, a geophysicist who researches the supercontinent cycle, offers a tour of past supercontinents; introduces readers to the phenomena that will lead to the next one; and presents the case for a particular future supercontinent, called Amasia, that will form over the North Pole. Mitchell uses compelling stories of fieldwork and accessible descriptions of current science to introduce readers to the nuances of plate tectonic theory. He considers convection deep in Earth's mantle to explain the future formation Amasia (defined by the joining of North America and Asia) and to show how this developing theory can explain other planetary mysteries. He ends the book by asking if humans will live to see Amasia. He recognizes the chances of our species surviving the necessary 50 to 200 million years are vanishingly small, but the exercise gives readers a chance to imagine this landscape and to understand mimics for the geological processes required, for example in the form of geoengineering. An internationally recognized authority on the supercontinent cycle, Mitchell offers a compelling and updated introduction that offers readers a front-row seat to an ongoing scientific debate"--

This paper has been written to aid the owner of a small gold mine or prospect in preparing a report on his property for the purpose of interesting capital. If an owner can afford to do so, he should employ a mining engineer of recognized standing and experience to examine and report on his property, but many owners of small mines and particularly of prospects cannot make the expenditure required for this. Further, many of them do not know how to prepare a description which will cover those features of a deposit on which a potential investor promises his opinion as to its worth. If such an owner is convinced that he possesses and orebody of sufficient grade and size to warrant the required expenditure for a thorough investigation and wishes to present his property to prospective investors, then the following suggestions concerning the proper way to sample his deposit, estimate the tonnage of developed and probable ore, and prepare a report may be of assistance.
