  1. 6. Microstructural evolution of ice under simple shear deformation

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Carina Liebl; [2021-01-11]
    Keywords : ;

    Abstract : To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation apparatus was tested and results from deformation were compared to literature to validate the method. READ MORE

  4. 8. An Investigation of the breakage process of particles : With help of experimental results and discrete element methods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ronni Bashiry; [2021]
    Keywords : Geotechnical Engineering; Breakage; Fracture; Spherical particles; DEM; Modelling; Numerical modelling;

    Abstract : In this study the breakage mechanics of brittle glass marbles was investigated. The pro-cess was to firstly investigate them in laboratory environment. The marbles or specimens was loaded until a crushing breakage occurred in a single point load test called Single Sphere Point load test in this document. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jaide Derbyshire; [2021]
    Keywords : Barsele; Structural Geology; Mineralisation; Deformation;

    Abstract : 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.

  6. 10. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Linnéa Jansson Fagerlund; [2021]
    Keywords : Geology; Northern Sweden; Gällivare; Nautanen Deformation Zone; Fjällåsen Deformation Zone; Microstructures;

    Abstract : The goal of this study was to identify and describe different microstructures observed in samples from two major shear zones in the Gällivare area, namely the Nautanen Deformation Zone (NDZ), and the Fjällåsen deformation zone (FDZ). Thirteen samples were examined during this study. READ MORE
