Download or read book Trondhjemites Dacites and Related Rocks written by F. Barker and published by Elsevier. This book was released on 2013-10-22 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Petrology, 6: Trondhjemites, Dacites, and Related Rocks focuses on the geology, geochemistry, and petrology of several kinds of trondhjemites, dacites, and genetically related rocks. The selection first elaborates on the definition, environment, and hypotheses of origin of trondhjemite; a review of the mineralogy and chemistry of tertiary-recent dacitic, latitic, rhyolitic, and related salic volcanic rocks; and some trace elements in trondhjemites and their implications to magma genesis and paleotectonic setting. Discussions focus on tectonic environments and trace element patterns, selection and reliability of trace elements, interrelationships between mineralogy and chemistry, and regional variations of dacitic and rhyolitic magmas. The publication then tackles strontium isotope geochemistry of late Archean to late Cretaceous tonalites and trondhjemites; Archean gray gneisses and the origin of the continental crust in West Greenland; and metamorphic development of early Archean tonalitic and trondhjemitic gneisses in Saglek Area, Labrador. The book examines the petrology, geochemistry, and origin of the Sparta quartz dioritetrondhjemite complex; reconnaissance geochemistry of Devonian island-arc volcanic and intrusive rocks in West Shasta District, California; and origin of the Twillingate trondhjemite in North-Central Newfoundland. The selection is highly recommended for geologists and geochemists wanting to explore trondhjemites, dacites, and genetically related rocks.

Download or read book Glacial and Environmental Geology of Northeastern Manitoba written by L. A. Dredge and published by . This book was released on 1992 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report and accompanying map describe and interpret the terrain conditions across 48,000 km2 of the coast and hinterland of Hudson Bay. The surface mapping of materials was combined with a study of river exposures in order to reconstruct the preglacial and glacial evolution of the landscape, and postglacial changes in permafrost, climate, and sea level. The geological interpretation was used to locate anomalously high concentrations of minerals of economic value, including gold and uranium, assess aggregate sources, identify areas of sensitive permafrost terrain, and to predict future environmental change.
