  1. 1. Rb-Sr sphalerite data and implications for the source and timing of Pb-Zn deposits at the Caledonian margin in Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alfred Larsson; [2018]
    Keywords : Laisvall; Granberget; geochronology; sphalerite; ore; Rb-Sr; Earth and Environmental Sciences;

    Abstract : The eastern Caledonian erosional front hosts the world-class Pb-Zn deposit at Laisvall (64 Mt mined) and Granberget mineralization, northern Sweden, along with several other smaller, related types of deposits consisting of impregnation mineralization of galena and sphalerite in clastic host rocks. Previous work have discussed the nature of the ore-forming processes and constraints for the timing of the mineralization, however, the mechanisms are still not fully understood and previous age determinations are ambiguous.

  2. 2. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Michele Riva; [2018]
    Keywords : LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Abstract : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. READ MORE

  4. 4. Magmatic Sources and Processes Recorded by the Volcanics from the Izu Bonin Rear Arc

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : John Owen Edgar; [2017]
    Keywords : Izu-Bonin; plagioclase; magma; strontium; thermobarometry; rear arc; Izu-Bonin; plagioklas; magma; strontium; termobarometri; bakbåge;

    Abstract : The Izu rear-arc volcanism was investigated by IODP EXP350 in spring 2014. A total stratigraphy of1800 m was drilled, and contains volcaniclastic material within tuffaceous mudstone. READ MORE

  5. 5. The status of neutron-capture elements according to Gaia-ESO.

    University essay from Lunds universitet/Astronomi

    Author : Linnéa Strandell; [2017]
    Keywords : Neutron-capture elements; Gaia-ESO; Milky Way field stars; Physics and Astronomy;

    Abstract : The aim of this thesis is to get a better understanding of the evolution of the Milky Way stellar disc by looking at the abundance ratios for neutron-capture elements in thin and thick disc stars. In this project the formation of our Galaxy’s thin and thick disc was studied by analysing 10 different neutron-capture elements in field stars measured by Gaia-ESO. READ MORE
