The Principles of Stratigraphical Geology

A concise manual explains methods and scope of stratigraphical geology, showing how relative chronology is established by superposition, fossil content, and classification. It describes the nature of stratified rocks, mapping and section-drawing, simulation of structures, and the interpretation of depositional conditions from field evidence. The author then applies these methods in a system-by-system survey of the geological column—from the earliest rocks through successive systems to the Pleistocene—treating regional cycles of change and later chapters on steppe and forest periods, and closing with remarks on classification and outstanding problems.
