  2. 1. Lithology of some Swedish eskers

    Author : Marianne Lilliesköld; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Three esker systems passing different bedrock areas are lithologically investigated. Mostparts of the eskers are of subglacial, subaquatic type. The existence of a preglacial furrowof the River Dalälven is proposed to be the cause of the longtransported lithologiesfound in the Badelunda esker adjacent to the furrow. READ MORE

  4. 2. Geophysical tools for prognosis of deformation in hardrock environments

    Author : Mai-Britt Mose Jensen; Satu Mertanen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AMS; Bergmekanik; Refleksions seismik; Gravimetri; Petrofysik; Tillämpad geofysik; Applied Geophysics;

    Abstract : Underground mining of the Kiirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly predict future deformation, a structural model of the hanging wall and a good understanding of the petrophysical and mechanical properties of the constituent rocks is necessary.

    Author : Carlos Cruz Ferrán; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : Paleomagnetic studies have been performed on Jurassic to Tertiary rocks in Cuba and Jamaica. Samples of predominantly volcanic and sedimentary rocks were collected at 73 sites and the study included 792 samples. READ MORE

  6. 4. Ore and rock mass characterization using borehole geophysics

    Author : Stefan Wänstedt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : A geophysical log represents the measurement of a geophysical parameter along a borehole, plotted against time or depth. A variety of geophysical logging tools exist that measure different geophysical parameters. READ MORE

  7. 5. Magmatic and hydrothermal processes in relation to the formation of the Aitik Cu-Au deposit, Northern Sweden

    Author : Christina Wanhainen; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : Aitik is a disseminated Cu-Au deposit with an annual production of 18 million metric tons of ore containing 0.38 percent copper and 0.22 parts per million gold. It is situated in northern Sweden in 1. READ MORE
