Copious illustrations and witty, page-turning prose guide readers on geologic walking or driving tours of 37 sites in Illinois.

Geology of Illinois has been compiled from more than a century of earth science investigations in Illinois. For the first time, this information has been summarized and made accessible in one volume to help both geologists and non-geologists better understand how the state's mostly unseen geology affects, and is affected by, life on the surface. More than 200 color photographs, maps, and drawings illustrate the text. Topics include : the history of geological investigations in Illinois; the impact of the state's tectonic and structural history; the properties and classification of its rocks and sediments; the rich heritage of its land, water, and mineral resources; the threats from its geological hazards; and the application of geological information to societal issues.

The 'Guide to the Geologic Map of Illinois' by the Illinois State Geological Survey is a comprehensive and meticulously detailed analysis of the geology of Illinois.

Written in a clear and informative style, the guide serves as an essential resource for geologists, researchers, and anyone interested in the earth sciences. This book not only serves as a valuable reference for understanding the geology of Illinois but also contributes to the broader field of geology with its detailed analysis and comprehensive coverage. The inclusion of detailed maps, charts, and illustrations further enhances the reader's understanding of the subject matter. The author's expertise and dedication to the study of Illinois geology shine through in this meticulously researched and carefully crafted guide. The 'Guide to the Geologic Map of Illinois' is a must-read for anyone looking to deepen their knowledge of the geological landscape of Illinois and beyond.

Chicago in Stone and Clay explores the interplay between the city's most architecturally significant sites, the materials they're made of, and the sediments and bedrock they are anchored in. This unique geologist's survey of Windy City neighborhoods demonstrates the fascinating and often surprising links between science, art, engineering, and urban history. Drawing on two decades of experience leading popular geology tours in Chicago, Raymond Wiggers crafted this book for readers ranging from the region's large community of amateur naturalists, "citizen scientists," and architecture buffs to geologists, architects, educators, and other professionals seeking a new perspective on the themes of architecture and urbanism. Unlike most geology and architecture books, Chicago in Stone and Clay is written in the informal, accessible style of a natural history tour guide, humanizing the science for the nonspecialist reader. Providing an exciting new angle on both architecture and natural history, Wiggers uses an integrative approach that incorporates multiple themes and perspectives to demonstrate how the urban environment presents us with a rich geologic and architectural legacy.

This 328-page hardback volume printed by the Illinois State Geological Survey includes over 1200 full-color, high-resolution photographs of fossil specimens collected from the Upper Ordovician Platteville Formation in the Upper Midwest USA. The described and illustrated fossil assemblage includes exceptionally well-preserved sponges, corals, bryozoans, brachiopods, polyplacophorans, gastropods, bivalves, rostroconchs, cephalopods, trilobites, ostracodes, echinoderms, graptolites, cornulitids, hyolithids, macroalgae, and a wide variety of trace fossils.This overview is directed to students, collectors, and professional paleontologists. Each chapter begins with a brief introduction to the morphological terms used to describe the various fossil groups, followed by systematic descriptions, remarks, and occurrence information. This overview can serve as a starting place and a source of inspiration for future paleontological research on the fossils of the Platteville Formation, offer insights regarding past climate and the environments in which life thrived, and ultimately shed light on the history of life on our planet.Many Platteville fossils were described in pre-20th century reconnaissance reports commissioned by the state geological surveys of Illinois, Iowa, Minnesota, and Wisconsin. A historical summary of paleontological investigations of the Upper Ordovician stratigraphic succession can be found in Sloan (1987). A drawback to understanding the documented faunal composition of the Platteville Formation is that many of the fossils are described and illustrated in diverse monographs and shorter papers spanning more than 150 years and published by a variety of organizations. Many of these publications are difficult to find in libraries and are not available online. Furthermore, they tend to focus on specific phyla rather than the overall faunal associations. An added drawback is that many early publications lack high-resolution photographs, making it difficult to compare and contrast fossil specimens.
