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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

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

    Abstract : 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.

  2. 2. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  3. 3. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tim Bjermo; [2022]
    Keywords : glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

    Abstract : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

  4. 4. Methods for rockfall risk assessment and estimation of runout zones: A case study in Gothenburg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Laura Catalina Agudelo Motta; [2020]
    Keywords : Rockfall hazard; rockfall simulation; Gothenburg; Fjällbo; runout zones; Earth and Environmental Sciences;

    Abstract : Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones.

  5. 5. Using Very-Low-Frequency Electromagnetics (VLF-EM) for geophysical exploration at Albertine Graben, Uganda : a new CAD approach for 3D data blending

    University essay from Lunds universitet/Geologiska institutionen

    Author : David Eggert; [2019]
    Keywords : Albertine Graben; EAR; East-African-Rift; Exploration; Geology; Geophysics; Ore; Uganda; Very Low Frequency; VLF-EM; Earth and Environmental Sciences;

    Abstract : Elektromagnetiska vågor, även kända som radiovågor, är vågor som sprider sig med låga frekvenser från 3 till 30 kHz. Dessa lågfrekventa vågor används vanligtvis när man önskar kommunicera med ubåtar. De kan emellertid också användas på land för att mäta skillnader i jord– och bergarters elektriska konduktivitet.
