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

The mining industry continues to be at the forefront of colonial dispossession around the world. It controls information about its intrinsic costs and benefits, propagates myths about its contribution to the economy, shapes government policy and regulation, and deals ruthlessly with its opponents. Brimming with case studies, anecdotes, resources, and illustrations, Unearthing Justice exposes the mining process and its externalized impacts on the environment, Indigenous Peoples, communities, workers, and governments. But, most importantly, the book shows how people are fighting back. Whether it is to stop a mine before it starts, to get an abandoned mine cleaned up, to change Laws and policy, or to mount a campaign to influence investors, Unearthing Justice is an essential handbook for anyone trying to protect the places and people they love.

For more than four decades, world-renowned diver and treasure hunter Captain Robert MacKinnon has reclaimed sunken caches from the dangerous shallow waters along the Atlantic coast of Cape Breton Island, Nova Scotia. Known as the Death Coast for its treacherous reefs and violent currents, the area’s rocky bottom is layered with shipwrecks and untold riches. In short—a treasure hunter’s paradise. In Treasure Hunter, Robert MacKinnon recounts the risks and challenges—both nautical and legal—in exploring shipwrecks dating back to the War of 1812 and before the Revolutionary War. As he salvages the secrets of the sea, MacKinnon vividly captures the excitement of discovery and conveys his passion for preservation in the still-developing field of underwater archeology. A compelling chronicle of modern-day adventure, Treasure Hunter is a fascinating voyage into an amazing undersea world.
