"General Information on Coal" is a comprehensive study detailing the geological formation, classification, and industrial significance of one of the world's most vital natural resources. Written by noted geologist George H. Ashley, this work serves as an authoritative guide to understanding the physical and chemical properties of coal, as well as the processes that lead to its creation over millions of years.The book explores the various grades of coal-from peat and lignite to bituminous and anthracite-explaining their distinct characteristics and heating values. Beyond the scientific analysis of the fuel itself, Ashley examines the practical aspects of the coal industry, including mining methods, distribution, and the role of coal in powering the modern industrial age.Designed for both students of geology and professionals in the energy sector, this text provides a foundational look at the resource that fueled the early 20th century. "General Information on Coal" remains a valuable historical document for those interested in the history of mining, economic geology, and the development of energy infrastructure. It offers a clear, technical, yet accessible overview of the complex world of fossil fuels.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
