Book excerpt: The map area is located east of Long Lake and comprises Daley Township and the eastern part of Ginoogaming First Nation Indian Reserve, formerly Long Lake Indian Reserve 77. Field work was carried out in summer 1988 and consisted of mapping the Precambrian bedrock and its mineral deposits. Rock samples were collected in the field, with 50 samples submitted for gold and silver assays, 40 for whole-rock geochemistry, and 88 for thin sectioning. This report describes the general geology, rock geochemistry, structural geology, metamorphism and alteration, geochronology, and economic geology of the area, including descriptions of existing properties, and the possibilities for gold, silver, base metals, iron, corundum, stone, and sand and gravel.

Available in PDF, EPUB and Kindle. Book excerpt: The motivation for this volume came from the idea that thePrecambrian is the key, both to the present, and to theunderstanding of the Earth as a whole. The Precambrian constitutesabout 85% of Earth's history, and of that, about 3.75 billion yearsof Precambrian time, represented by rocks, are accessible togeoscientists. Ancient atmospheric and environmental conditions canbe traced back to the time when the Earth was only about 250million years old. Precambrian rocks supply almost 75% of importantmineral resources such as Fe, Mn, Au, Pt and Cr. Many of theseelements are associated with sedimentary rocks and some importanthydrocarbon, coal and graphite deposits are also hosted byPrecambrian rocks. This volume is aimed at geoscientists interested in Precambriansedimentary rocks and at students of Earth history. It containsreview articles discussing Precambrian conditions and case studiesfrom Precambrian shields and successions of North and SouthAmerica, Australia, Africa, Europe, Asia and India. Theintroductory papers, written by experts on Precambrianenvironments, treat comprehensively the application of actualism tothe Precambrian, the evolution and influence of life on thesedimentary rock record, the genesis of Banded Iron Formations, thePrecambrian sulphur cycle and the significance of Precambrianchemical carbonate precipitates. The case studies includedepositional settings and processes in Archean terranes, inPaleoproterozoic sequences, with some emphasis on the lack ofvegetation and weathering, and in late Proterozoic sequences, withsome emphasis on glacial deposits. The contributions demonstratethat Precambrian sedimentary deposits are commonly similar to theirPhanerozoic counterparts in terms of composition, sedimentaryprocesses, and depositional setting, but may differ significantlyas a result of lack of vegetation, climatic and biologicalconstraints, composition and circulation of seawater, and thesecular involvement of continental crust.

Book excerpt: In this book the editors strive to cover all primary (i.e. non-applied) topics in Precambrian geology in a non-partisan way, by using a large team of international authors to present their datasets and highly divergent viewpoints. The chapters address: celestial origins of Earth and succeeding extraterrestrial impact events; generation of continental crust and the greenstone-granite debate; the interaction of mantle plumes and plate tectonics over Precambrian time; Precambrian volcanism, emphasising komatiite research; evolution and models for Earth's hydrosphere and atmosphere; evolution of life and its influence on Precambrian ocean chemistry and chemical sedimentation; sedimentation through Precambrian time; the application of sequence stratigraphy to the Precambrian rock record. Each topic is introduced and a non-partisan closing commentary provided at the end of each chapter. The final chapter blends the major geological events and rates at which important processes occurred into a synthesis, which postulates a number of "event clusters" in the Precambrian when significant changes occurred in many natural systems and geological environments.

Book excerpt: Barbara, Meader, and Pifher townships lie on the eastern side of Lake Nipigon and cover an area of 240 sq km. Field work was carried out during the summer of 1986 and consisted of mapping the Precambrian bedrock and mineral deposits. A large number of rock samples were collected, of which 94 were submitted for assays, principally gold and silver, 95 for thin sectioning and 54 for whole rock analysis. This report describes the geology, mineral deposits and exploration history of the area, as well as specific mines.
