  1. 16. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia

    University essay from Uppsala universitet/Geofysik

    Author : Vessela Hobson; [2019]
    Keywords : refraction seismics; tomographic inversion; Zambian Copperbelt; copper;

    Abstract : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

  3. 17. Simulation of Leachate Generation from a Waste Rock Dump in Kiruna Using HYDRUS-1D

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aryani Atmosudirdjo; [2019]
    Keywords : Hydrus-1D; matrix flow; leachate; unsaturated flow; waste rock dump;

    Abstract : The percolation of water through waste rock dumps at mine sites can lead to the production of a leachate with high concentrations of dissolved metals, sulfate and nitrogen compounds. It is important to understand how water flows in waste rock dumps in order to predict the environmental impact of this leachate on recipients. READ MORE

  5. 19. Palaeomagnetism and Magnetic Fabrics of The Lake Natron Escarpment Volcano-sedimentary Sequence, Northern Tanzania

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gülsinem Polat Wiers; [2019]
    Keywords : Natron Escarpment; Northern Tanzania; Paleomagnetism; Geomagnetic Polarity Time Scale; Anisotropy of Magnetic Susceptibility;

    Abstract : The East African Rift System diverges in the Lake Natron Basin of Northern Tanzania and is a major zone of continental extension and crustal thinning with resulting in active tectonics and volcanism. The discovery of Acheulean technology in Olduvai Gorge and Peninj as well as the presence of significant volcanic centers, has made in the region subject to studies in various disciplines. READ MORE

  6. 20. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Filip Ivarsson; [2019]
