Book Description
This study of the Precambrian geology of part of the Tavani map area (southwest of Rankin Inlet, Keewatin District, Northwest Territories), describes the Rankin-Ennadai greenstone belt with a revised stratigraphic subdivision of the supracrustal rocks, and the deposition and deformation of an Early Proterozoic cover sequence to this basement.

Book Description
The Hackett River area lies just south of the Arctic Circle, some 500 km northeast of Yellowknife. This report incorporates data from a mid-1970s mapping and compilation of data, as well as more detailed work on economic geology, volcanology, geophysics and geochemistry.

Book Description
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 Description
The study was prompted by a need for data on terrain conditions, soil materials, and glacial transport, which was required for mineral exploration, for the planning of a hydroelectric transmission corridor, for bedrock mapping, for forest inventory, and for land capability studies. A secondary reason for beginning a program of surficial mapping in this part of Newfoundland was the paucity of Quaternary geological information in a key area about which early reports debated the extent of glaciation, and where airphoto reconnaissance revealed significant new glacial and marine formations.
