Sketches in Geology

'Sketches in Geology; A Group of Twenty-Two Separate Papers on American Geology' is a comprehensive collection of scientific essays authored by Willard Rouse Jillson, a prominent figure in American geological studies. This work brings together twenty-two distinct papers that explore the diverse landscape and subsurface characteristics of the United States, with a particular emphasis on the geological formations and mineral resources found within the Appalachian and mid-continental regions. The collection delves into a variety of technical subjects, including stratigraphy, paleontology, and economic geology. Readers will find detailed observations on coal deposits, oil and gas potential, and the structural evolution of specific landforms. Jillson’s writing combines rigorous scientific inquiry with a narrative style that makes complex geological processes accessible to both professionals and dedicated enthusiasts of the natural sciences. As a significant contribution to early 20th-century earth science, this volume provides valuable historical context for the development of geological surveys in America. It serves as an essential resource for those interested in the history of science, regional American geography, and the foundational research that shaped our understanding of the continent’s physical history.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
