Available in PDF, EPUB and Kindle. Book excerpt: Much new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.

This book was released on 1994 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Proterozoic Michigamme Formation of northern Michigan was deposited in the southeastern part of the Animikie basin. The formation conformably overlies the Goodrich Quartzite and comprises three widespread members a lower member of thin-bedded shale, siltstone, and sandstone; the Bijiki Iron-formation Member; and an upper member of tur- biditic graywacke, siltstone, and mudstone and a few local members. The Goodrich Quartzite is interpreted as having been deposited in a tidally influenced shallow marine environ- ment. The lower member of the Michigamme is interpreted as having been deposited in a tidally influenced environment, the iron-formation member as having been deposited below wave base in somewhat deeper water, and the upper member as having been deposited in still deeper water with turbidity currents being a major depositional mechanism. Several lines of evidence including paleocurrents, paleo- geographic setting, and neodymium isotopes suggest that the graywacke of the southern part of the outcrop area was derived from the south (Early Proterozoic Wisconsin magmatic terranes, Archean miniplates, and older Early Proterozoic sedimentary units formed on the continental margin), and that the graywacke in the northern area was derived from an Archean terrane to the north. The tectonic model that best fits the available data is a northward-migrating foreland basin.
