Available in PDF, EPUB and Kindle. Book excerpt: The copper potential of the area has been investigated many times, most recently in 1966-69, but none of the deposits discovered has yet proven to be exploitable. Most bedrock is of Proterozoic age and includes sedimentary and volcanic successions, older granite intrusions, and upper Proterozoic gabbro and diabase sills. Pleistocene deposits are widespread. ice flow was generally from the southeast. Marine deposits that mark an advance of the sea in the immediate postglacial period are about 350 feet above present sea level.

Available in PDF, EPUB and Kindle. Book excerpt: "The stratigraphic succession of the area extends from Proterozoic to Upper Cretaceous, and is interrupted by four or more unconformities. The sub-Cambrian and sub-Cretaceous unconformities are the most pronounced, whereas the sub-Upper Ordovician and sub0Devonian unconformities are less obvious. A fifth unconformity may be present between Lower and Upper Cretaceous shales." "This paper is intended as a brief set of notes to amplify the geologic map."

Available in PDF, EPUB and Kindle. Book excerpt: Arc-continent collision has been one of the important tectonic processes in the formation of mountain belts throughout geological time, and it continues to be so today along tectonically active plate boundaries such as those in the SW Pacific or the Caribbean. Arc-continent collision is thought to have been one of the most important process involved in the growth of the continental crust over geological time, and may also play an important role in its recycling back into the mantle via subduction. Understanding the geological processes that take place during arc-continent collision is therefore of importance for our understanding of how collisional orogens evolve and how the continental crust grows or is destroyed. Furthermore, zones of arc-continent collision are producers of much of the worlds primary economic wealth in the form of minerals, so understanding the processes that take place during these tectonic events is of importance in modeling how this mineral wealth is formed and preserved. This book brings together seventeen papers that are dedicated to the investigation of the tectonic processes that take place during arc-continent collision. It is divided into four sections that deal firstly with the main players involved in any arc-continent collision; the continental margin, the subduction zone, and finally the volcanic arc and its mineral deposits. The second section presents eight examples of arc-continent collisions that range from being currently active through to Palaeoproterozoic in age. The third section contains two papers, one that deals with the obduction of large-slab ophiolites and a second that presents a wide range of physical models of arc-continent collision. The fourth section brings everything that comes before together into a discussion of the processes of arc-continent collision.

This book was released on 1972 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the summer of 1970, the Geological Survey of Canada carried out helicopter-supported regional and detailed lake sediment and water sampling programs over a 1,500-square-mile area of the Coppermine River basalts. The survey extended over the geographic center of the basalt belt and adjacent overlying and underlying sediments. [...] The study described here was the first regional geochemical survey undertaken.

Available in PDF, EPUB and Kindle. Book excerpt: Gently folded, unmetamorphosed Upper Proterozoic (Hadrynian or Neohelikian) sedimentary rocks, with a total exposed thickness of about 6,000 feet, underlie most of the map-area; gabbro sills and dykes locally intrude the strata. Paleozoic, marine sedimentary rocks, ranging in age from Cambrian to Middle Devonian, and having an exposed thickness of about 1,700 feet, uncomformably overlie the Proterozoic rocks. Paleozoic rocks are separated by a regional hiatus from the overlying Cretaceous sequence that is about 700 feet thick and composed of quartz sandstones, siltstones, shale and coal. Thick, topographically prominent, Pleistocene glacial deposits obscure bedrock throughout wide regions.
