Contributions To Economic Geology 1907 PDF Download

Excerpt from Contributions to Economic Geology, 1906, Vol. 2: Coal, Lignite, and Peat The constantly growing consumption of coal in the United States has led to the opening of mines in almost every State in the Union and it has also stimulated prospecting to a marked degree. This condition of affairs has created a strong demand for information con cerning the extent of the coal fields, the geologic relation of the beds, and the quality of the coal. In the comparatively unknown coal fields of the West the demand is for general information regarding the extent, number, and thickness of the beds and the quality of the coal. In the better known fields the demand is for detailed information which will enable the prospective operator to know how much of any one coal bed is available, and how it lies, so that he may locate his mine in the best position for economic work.
