  1. 1. En sammanställning av norra Skånes prekambriska berggrund

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Simon Andersen Staahlnacke; [2018]
    Nyckelord :Skåne; prekambrium; svekonorvegiska provinsen; protoginzonen; orogenes; Earth and Environmental Sciences;

    Sammanfattning : This literature study aims to summarize the Precambrian bedrock and its geological development in northern Scania. The study is based on previously published material, primarily three of SGU’s bedrock maps: Af 127, 155 and 181. These show the bedrock in the area northeast, southwest and northwest of Kristianstad.

  3. 2. A Petrological Investigation of the Host Rocks for the Kuj-Kiirunavaara Ore

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Holger Sandberg; [2018]
    Nyckelord :Kiirunavaara; optical mineralogy; hydrothermal alteration; electron microprobe; Kiirunavaara; optisk mineralogi; hydrotermal omvandling; elektron-mikrosond;

    Sammanfattning : The Kiirunavaara mine hosts one of the world’s largest apatite-iron ore mineralisations. This ore body has been subject to large amounts of research as well as extensive mining. The ore body is situated between the syenitic foot wall and the rhyodacitic hanging wall, of which consists of differing mineralogy and characteristics. LÄS MER

  4. 3. Magma Storage of the Alkaline Tejeda Cone Sheet Swarm, Gran Canaria, Spain

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Max Jensen; [2016]
    Nyckelord :Gran Canaria; Tejeda cone sheet swarm; syenite; magma storage; thermobarometry; clinopyoxene; Gran Canaria; Tejeda inverterade kon-intrusioner; syenit; magma förvar; termobarometri; klinopyroxen;

    Sammanfattning : Volcanoes with alkaline differentiated magma belong to the more explosive and destructive types, but knowledge about these systems is often limited. Unravelling the position and conditions in the source magma chamber systems that feed volcanism at the surface is vital to understand these systems better. LÄS MER

  5. 4. En strukturgeologisk modell för berggrunden i Sarvesvagge-Luottolako-området, Sareks Nationalpark, Lappland

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Mats G. Lund; [1999]
    Nyckelord :Caledonides; overthrusting; duplex; tectonostratigraphy; structural geology; Sarek; Earth and Environmental Sciences;

    Sammanfattning : The high plateau of Luottolako constitutes a topographical area strongly contrasting from the rugged Sarek Mountains. Older geological maps show that not only the topography, but also the bedrock is different compared to the surrounding massifs. However, the boundaries in the previously publis-hed maps indicate impossible structural models. LÄS MER

  7. 5. Tektonostratigrafi och strukturgeologi i Ålkatj-Tielmamassivet, norra svenska Kaledoniderna

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Emma Rehnström; [1998]
    Nyckelord :geografi; geologi; Ålkatj-Tielmamassivet; tektonostratigrafi; strukturgeologi; svenska Kaledoniderna; Earth and Environmental Sciences;

    Sammanfattning : The bedrock of the Ålkatj-Tielma massif in the central part of the Sarek National Park in the northern Scandinavian Mountains, has never before been investigated. This massif was mapped during the summer of 1997 and the bedrock consists entirely of Caledonian nappes. LÄS MER
