关于此电子书
""Turquoise Formation"" explores the geological origins of this prized gemstone, revealing the fascinating interplay of Earth sciences that create its unique blue-green hue. This book examines how specific arid environments, rich in copper deposits and influenced by distinct geological processes, are essential for turquoise to form. Readers will discover how the convergence of copper, aluminum, and phosphorus, combined with weathering and groundwater activity, leads to the crystallization of turquoise. The cultural significance of turquoise, particularly its use in jewelry and by indigenous cultures, adds another layer of intrigue.
The book progresses systematically, starting with the geochemical processes and the role of host rocks. It then explores geological settings such as porphyry copper deposits and volcanic terrains, highlighting examples from the southwestern United States, Iran, and China. Finally, it delves into mineral identification, mineralogy, and the cultural importance of turquoise across different societies. This comprehensive approach provides valuable insights for gem and mineral collectors, jewelers, and anyone interested in the Earth's dynamic processes.
