Paperback. Condizione: New. Print on Demand. This book proposes that the formation of mineral veins, particularly the mechanical structure and contents, is a result of the earth's galvanic currents and electrical forces. The author, a seasoned professional miner, describes in detail his own observations and years of research into electrical and galvanic phenomena, and how these phenomena could explain many subterranean anomalies. His experiments and theories are illustrated by plans and sections of actual mines, and address the origin of strata and mineral veins, as well as the formation of ore deposits and other geological processes. Grounded in both scientific research and the author's extensive experience, this book provides a fascinating and novel perspective on mineral vein formation.
