  2. 1. The dynamic emplacement of felsic magma in the upper crust

    Author : Tobias Mattsson; Steffi Burchardt; Karen Mair; Christoph Breitkreuz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laccolith; cryptodome; magma emplacement; magma flow; magma rheology; granite; rhyolite; pluton; AMS; XCT; thermobarometry; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : Felsic magma intrudes earth’s upper crust through a variety of mechanisms. Magma intrusion growth and shape have mainly been explained in terms of host rock properties and intrusion depth, while considering the magma as an overpressurised fluid. READ MORE

  4. 2. Leave no trace: A non-destructive correlative approach providing new insights into impactites and meteorites

    Author : Josefin Martell; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; impact cratering; Mars; Mien impact structure; X-ray tomography; Neutron tomography; Shock metamorphism; Impact structure;

    Abstract : Impact cratering is today recognized as a fundamental geological process on all rocky bodies in the solar system. On Earth, however, processes such as plate tectonics and erosion have eradicated most craters from the geological record, or they may be buried under sediments, oceans, and vegetation. READ MORE

  5. 3. Defects and Surfaces and their Impact on Fatigue Behaviour of Powder Bed Fused Ti-6Al-4V : Characteristics and Modelling

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Stefano Beretta; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Extreme Value Statistics; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM), of metals is gaining popularity as an alternative to conventional manufacturing techniques such as casting and forging. Metal-AM allows for the production of complex part geometries with reduced material waste and shorter lead times. READ MORE

  6. 4. Multi-scale fabric evolution during hydro-mechanical probing of fine-grained soils

    Author : Georgios Birmpilis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray Computed Tomography; clay fabric; geomechanical testing; sensitive clays; X-ray Scattering;

    Abstract : The majority of the studies on sensitive clays so far have focused on the hydro-mechanical response at engineering scale, using concepts from continuum mechanics. The fundamental mechanisms at particle scale, underpinning the emerging response, have so far been studied with post mortem analyses. READ MORE

  7. 5. Improving trace metal characterisation of ore deposits through multi-modal, multi-scale, and multi-dimensional micro-analysis

    Author : Mathis Warlo; Christina Wanhainen; Glenn Bark; Alan R Butcher; Nigel Cook; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ore Geology; Malmgeologi;

    Abstract : The variety and amount of metals consumed by human society is ever increasing. Meeting the demand requires exploration for new ore deposits, efficient production of active mines, and improved efficiency in metal recycling. A key element in mining-related enterprises is the improvement of ore characterisation. READ MORE
