  1. 1. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER

    Sammanfattning : The Caledonian alum shales of Sweden host a vast number of economically interesting metals. In Fetsjön, Västerbotten, the shales contain significant amounts of rare-earth elements, vanadium, molybdenum and uranium. LÄS MER

  4. 3. Cambrian stratigraphy and depositional dynamics based on the Tomten-1 drill core, Falbygden, Västergötland, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Frans Lundberg; [2016]
    Nyckelord :biostratigraphy; Sweden; Västergötland; drill core; agnostoids; trilobites; δ13 excursion DICE ; Cambrian; carbon isotope stratigraphy; Earth and Environmental Sciences;

    Sammanfattning : The Tomten-1 drilling at Torbjörntorp in Västergötland, southern Sweden, penetrated 29.85 m of Cambrian Series 2 and 3, Furongian, and Lower and Middle Ordovician strata. The biostratigraphy, sedimentology and carbon isotope (δ[sup]13[/sup]C[sub]org[/sub]) stratigraphy of the core have been analysed. LÄS MER

  5. 4. Paleontology and Sedimentology of the Alum Shale Formation at Björnberget, Västerbotten County, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Sammanfattning : A new locality of the Alum Shale Formation at Björnberget, Västerbotten County, of the lower allochthon of the Caledonian front is described herein. Two new species of acrotretid brachiopods were found. Tingitanella vilhelminia n. sp. LÄS MER

  7. 5. Release of elements from unprocessed- and processed shale from Kvarntorp : Effect from different pH

    Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Lovisa Karlsson; [2013]
    Nyckelord :shale; Kvarntorp; extraction; pH; element; metal; DOC; precipitation; refuse; weathering; sulphate; adsorption;

    Sammanfattning : The alum shale of Sweden is a sulphidic black shale which was mined for its contents of alum during the 17th-19th centuries. During the thirst half of the 20th century alum shale from Kvarntorp was pyrolysed for refinement of its organic matter. LÄS MER
