Paperback. Etat : New. Print on Demand. This book explores the lignite tertiary formation in the vicinity of the 49th parallel, which marks the border between the United States and Canada. The author, an associate of the Royal School of Mines, conducted a geological survey of the area in 1873. He begins with an examination of the lignite beds found in the Souris River Valley, describing their composition, quality, and potential economic value, which was hindered by the lack of a coherent coke formation. Some of the lignite beds were found to include fossilized plant life, which provided a fascinating look at the region's ancient flora. The book also delves into the ironstone deposits associated with the lignite beds, which showed promise for industrial use, although their thickness varied. Overall, this book offers valuable insights into the geological formations and natural resources of a specific region, making it a valuable resource for geologists, historians, and anyone interested in the natural history of North America.
