Download or read book Geological Survey of Canada Current Research Online no 2005 A3 written by I. Rod Smith and published by Natural Resources Canada. This book was released on 2005 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted in response to concerns raised by local residents about water quality in Fisherman Lake, located 18 kilometres north-west of Fort Liard, Northwest Territories. Field investigation of the lake revealed the existence of 13 gas seeps (largely methane) with distinct bubble trains rising continuously to the surface. This paper presents results of analyses of the gas & of the lake water and the determination, through isotope analyses, of whether the gas is of biogenic origin (related to the decomposition of organic matter) or thermogenic origin (representing a seep from geological strata of the gas field below the lake). The possible effects of methane on the lake water are also discussed and recommendations are made for further research.
Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
Download or read book Cedar Mountain and Dakota Formations Around Dinosaur National Monument written by Douglas A. Sprinkel and published by Utah Geological Survey. This book was released on 2012 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 20 page report describes the stratigraphy of the Cedar Mountain and Dakota formations in and around Dinosaur National Monument in northeast Utah and includes new palynology and radiometric age data. The contract between these formations is unconformable in which the Dakota formation has incised into the underlying Cedar Mountain formation. Locally, the Dakota includes a basal marine mudstone and shale unit that contains late Albian dinoflagellate cysts, which represents peak sea level during the Kiowa-Skull Creek depositional cycle and indicates the first marine incursion of the Cretaceous Western Interior Seaway into Utah.
Download or read book Alluvial Fans written by Adrian M. Harvey and published by Geological Society of London. This book was released on 2005 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.
