  1. 1. A Structural Analysis of the Fracture Sets in Gothenburg, Sweden: A Remote Sensing and Manual Lineament Approach

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jacek Krysik; [2023-05-22]
    Nyckelord :Remote sensing; Manual lineament analysis; Fractal analysis; Structural; Regional geology; LiDAR; Gothenburg region;

    Sammanfattning : The fracture-valley landscape within the Gothenburg region was analysed based on LiDAR-derived hillshade images as well as several sources of orthomosaics. Using a manual lineament interpretation approach and complimented with an objective fractal analysis software (FROST), the objective of the study was to characterise the regional fracture sets as well as attempt to link the sets to the complex regional geological history.

  3. 2. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Pieslinger; [2023]
    Nyckelord :ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

    Sammanfattning : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. LÄS MER

  4. 3. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Sara Emilie Hansen Österlund; [2023]
    Nyckelord :interpolations; geographic information system; GIS; geochemistry; till; geology;

    Sammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER

  5. 4. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Linn Barreby; [2022]
    Nyckelord :Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

    Sammanfattning : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. LÄS MER

  7. 5. Hållbar besöksnäring inom geoturism : En fallstudie gällande Geopark Siljan, Dalarna

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Jessika Torneport; [2021]
    Nyckelord :Geoparks; tourism; natural impact; soil wear; erosion; climate change; regional development.; Geoparker; besöksnäring; naturpåverkan; markslitage; erosion; klimatförändring; regional utveckling.;

    Sammanfattning : Dalarnas län har berikats med Geopark Siljan som är Sveriges första internationella geopark. Med sin spännande historia väcker geoparken ett ökatintresse för naturvärde och geologi hos de som besöker geoparken. LÄS MER
