Book Description
Sm-Nd survey of Precambrian granitic and metasedimentary rocks collected from several geophysically defined blocks in central Minnesota confirms the presence of some fundamental geologic boundaries previously mapped on the basis of structure. The Malmo discontinuity an Early Proterozoic structure separates the Archean Minnesota River Valley ter- ranes from an Early Proterozoic (Penokean magmatic) terrane and the McGrath Gneiss dome of east-central Minnesota North of this boundary, the Penokean fold-and-thrust belt can be divided into fault-bounded terranes that were assembled during the Penokean orogeny. Each terrane within the study area has distinct crust formation ages.

Book Description
The geologic story of the Great Lakes region is one of the most remarkable of any place on Earth. Great Lakes Rocks takes readers on this fascinating journey through geologic history, beginning with an investigation of the surface features—the hills and valleys, waterfalls and caves, and the Great Lakes themselves—that we encounter on a daily basis. From there the book digs deeper into the past, and readers learn about the amazing techniques geologists have used to reconstruct the events that shaped this region millions and even billions of years before humans set foot on Earth. Throughout, the book gives special attention to the link between the region’s geology and its modern history, including the impacts of geology on settlement patterns as well as the development of industries and the present-day economy. Other discussed topics include natural hazards that are geologic in nature, including earthquakes, floods, landslides, and coastal erosion, as well as information on rocks, minerals, and ancient life seen in fossils. Written for nonspecialist readers, this book provides a detailed but easy-to-follow introduction to the geology of the Great Lakes region, and it is an ideal fit for introductory geology courses, including those aimed at nonscience majors.
