  2. 1. Environmental impact of alum shale mining in Kvarntorp, Närke, Sweden

    Author : Kristina Åhlgren; Mattias Bäckström; Stefan Karlsson; Roger Herbert; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alum shale; black shale; oil shale; Kvarntorp; uranium; surface water; groundwater; open pits;

    Abstract : Due to scarcity of imported liquid fuel during World War II, alum shale was mined for oil production in the Kvarntorp area 1942-1966. The shale contains both organic matter (kerogen) and elevated concentrations of trace elements such as molybdenum, nickel, uranium and vanadium. READ MORE

  4. 2. Survival of the Unfit : Path Dependence and the Estonian Oil Shale Industry

    Author : Rurik Holmberg; Staffan Laestadius; Mats Bladh; Mats Söderström; Nick von Tunzelmann; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Estonia; oil shale; path dependence; lock-in; institutions; knowledge; Sweden; innovation; Soviet Union; technology; systems; energy; shale oil; electricity; fossil fuel; environment; economy; Technology and social change; Teknik och social förändring;

    Abstract : Estonia is the only country in the world, which is totally dependent on oil shale in its energy system. Although this fossil fuel exists in enormous quantities around the world, it has so far not been utilized on a larger scale. The reasons for this have been both economic and, in recent times, ecological. READ MORE

  5. 3. Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland and the equivalent Killeröd Formation in Skåne, Sweden

    Author : Kristina Månsson; Berggrundsgeologi; []

    Abstract : Trilobites from the Middle and Upper Ordovician Andersön Shale Formation in Jämtland, central Sweden, and the Middle Ordovician Killeröd Formation in Skåne (Scania), southern Sweden, are revised and discussed. These formations have several genera and a few species in common, e.g. READ MORE

  6. 4. Weathering of mining waste rock containing alum shale and limestone

    Author : Erik Puura; KTH; []
    Keywords : ;

    Abstract : Geochemical processes occurring in the waste rock dumps ofan old phosphate mine, located in Maardu, northem Estonia, havebeen studied and modelled. The waste rock contains pyritic,metalliferous and organic-rich shale, as well as limestone.Production of acidity during pyrite oxidation is a potentialmechanism for heavy metal release. READ MORE

  7. 5. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

    Author : Jörgen Samuelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; petroleum; vitrinite reflectance; thermal maturation; flexural rigidity; heat flow; suppression; thermal conductivity; North West Shelf; Alum Shale;

    Abstract : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny. READ MORE
