Download or read book New Observations on the Age and Structure of Proterozoic Quartzites in Wisconsin written by Gene L. LaBerge and published by . This book was released on 1991 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proterozoic quartzite is exposed at several isolated localities within an area of nearly 13,000 square kilometers in Wisconsin. Although early workers proposed that the quartzite is of two different ages, more recent workers have suggested that the various quartzite bodies are correlative, and that their protoliths were deposited between 1,760 and 1,630 Ma. Structural and stratigraphic studies of the quartzite deposits together with new age data indicate that the quartzite is at least of two distinct ages. Quartzite at McCaslin and Thunder Mountains, in northeastern Wisconsin, is older than 1,812 Ma, as indicated indirectly by a dated intrusion, and quartzite boulders in conglomerates in central Wisconsin are at least as old as the rhyolite country rock (=1,840 Ma). Deformed quartzite at Hamilton Mounds, in south-central Wisconsin, is intruded by undeformed granite that is 1,764 Ma. The ages of many other quartzite bodies, however, cannot be tightly constrained at present. Quartzite exposed in central and southern Wisconsin, south of the Eau Pleine shear zone, is interpreted as remnants of a passive margin sequence that was deposited on an Archean microcontinent (Marshfield terrane) and subsequently deformed in a major south-verging fold-thrust system during collision between the microcontinent and oceanic-arc rocks of the Pembine-Wausau terrane. The occurrence of quartzite-bearing conglomerates in the 1,860 Ma volcanic rocks of the Marshfield terrane suggests that the allochthonous quartzite bodies are 1,860 Ma or older. Collision occurred at about 1,840 Ma, and marked the end of the Penokean orogeny.

Download or read book Wisconsin Waters written by Scott Spoolman and published by Wisconsin Historical Society. This book was released on 2022-07-26 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every Wisconsin waterway has a story, from the Great Lakes and the Mighty Mississippi to thousands of interior lakes, rivers, and trout streams. Wisconsin Waters takes readers on an epic tour of the geologic, natural, and human stories that have shaped these aquatic landscapes over millions of years. In this companion to his popular Wisconsin State Parks book, Scott Spoolman journeys to the distant past to examine the origins of Wisconsin’s lakes, rivers, waterfalls, and wetlands. In his accessible storytelling style, Spoolman details the natural forces—volcanic eruptions, ancient seas, erosion, glaciers, and more—that created these bodies of water and the resulting habitats for the state’s flora, fauna, and early peoples. More than a geology or natural history book, Wisconsin Waters invites readers to visit waterways in four regions of the state, where they can view the modern-day evidence of how they were formed. Nineteen travel guides suggest ways to explore a selection of Wisconsin waterscapes, providing a better understanding of the land’s history that will enhance readers’ enjoyment of and appreciation for our freshwater resources.
