  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. Integration of geology with geophysics : Case studies from Svalbard

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sofia Rylander; Anna Sterley; [2022]
    Nyckelord :Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Sammanfattning : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). LÄS MER

  5. 4. Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ellinor Halvarsson; [2022]
    Nyckelord :Frontal wedge; deformation zone; Sveconorwegian orogeny; Sveconorwegian Orogen; Eastern Segment; shear-sense indicators; Protogine zone; structural geology; bedrock geology; Earth and Environmental Sciences;

    Sammanfattning : Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. LÄS MER

  7. 5. The Structural Architecture of the Barsele Area, Sweden : Characterising the deformation events and mineralisation

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jaide Derbyshire; [2021]
    Nyckelord :Barsele; Structural Geology; Mineralisation; Deformation;

    Sammanfattning : Located at an important intersect between orogenic Au deposits in Sweden’s Gold Line and volcanicmassive sulphide (VMS) deposits in the Skellefte Mining District, the Barsele area is of high interest.Currently, the Barsele deposit consists of the Norra VMS deposit and 3 intrusive-hosted orogenic Audeposits: Avan, Central, and Skiråsen which are hosted in a 1876 ± 10 Ma early orogenic granodiorite(Thomas, et al.
