  1. 1. Volcanology of the paleoproterozoic Maurliden area and its four unusual massive sulphide deposits, Skellefteå district, Sweden

    Författare :Cecilia Montelius; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Skellefte district is one of three major ore provinces in Sweden and contains more than 85 Zn-Cu-Au-Ag massive sulphide deposits. The Maurliden area is situated in the central part of the district and is a subaqueous volcanic dominated area with four Zn-Pb-Cu-Au-Ag sulphide deposits. LÄS MER

  3. 2. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics

    Författare :Simon Pontér; Anders Widerlund; Hjalmar Laudon; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isotope ratio measurements; screening analysis; ICP-MS; MC-ICP-MC; multi-tracer studies; fractionation; Environmental Forensics; Tracing; Tillämpad geokemi; Applied Geochemistry;

    Sammanfattning : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.

  4. 3. Studies on Industrial-Scale Thermal Modification of Wood

    Författare :Ola Dagbro; Lidia Gurau; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry and Wood Technology; Skog och träteknik; Wood Physics;

    Sammanfattning : Wood as a raw material is useful for many purposes even though some properties are less than optimal, for example, dimensional stability and durability. These characteristics can however be improved by different treatment methods. LÄS MER

  5. 4. Nya litologiska-tektoniska modeller för regionen Västerbotten - södra Norrbotten

    Författare :Dan H. Nisca; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : High quality bedrock and tectonic maps are the platform for locating natural resources such as ore, oil, gas, and water. Bedrock maps are also used in the design of large constructions, including highways, bridges, dams, power plants, tunnels, nuclear and other waste repositories. LÄS MER
