Aggiungi al carrelloPaperback. Condizione: New. Print on Demand. This book explores the origins of gold and its ubiquity throughout the Earth. The author argues that all gold was originally present in igneous rocks but then separated and aggregated into veins, seams, and deposits scattered across the globe. Through a wide-ranging examination of gold's behavior in the Earth, the author posits that the precious metal began as dispersed ions and were leached from the surrounding igneous rocks and deposited in veins by circulating waters. The author traces gold throughout Earth's history, from its initial concentration in the planet's crust through its metamorphosis due to water circulation and pressure, to its eventual emergence in a myriad of forms including nuggets, grains, and alluvial sediments. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
