  2. 2. New constraints on paleoreconstructions through geochronology of mafic dyke swarms in North Atlantic Craton

    University dissertation from Lund University, Faculty of Science, Department of Geology, Lithosphere and Biosphere Science

    Author : Mimmi Nilsson; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; baddeleyit; U-Pb; geokronologi; large igneous province; mantelplym; superkontinent; paleorekonstruktion; North Atlantic craton; baddeleyite; Large Igneous Province; Mantle plume; supercontinent; paleoreconstruction; U-Pb; geochronology; North Atlantic craton;

    Abstract : Earth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. READ MORE

  3. 3. Terrestrial consequences of hypervelocity impact – shock metamorphism, shock barometry, and newly discovered impact structures

    University dissertation from Lund University, Faculty of Science, Department of Geology, Lithosphere and Biosphere Science

    Author : Sanna Alwmark; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Impact cratering; Impact structure; Shock metamorphism; Shock barometry; Quartz; Planar deformation features; Siljan; Målingen; Hummeln;

    Abstract : Impact cratering was once considered a rare geological process of no, or little, importance to the evolution of the Solar System and planet Earth. After more than 50 years of space exploration and the discovery of numerous (~190 as of October 2016) impact structures on Earth, this view has changed, and it is now clear that impact craters are in fact one of the most common morphological features on solid bodies in the Solar System.

  4. 4. Metamorphic zircon formation in gabbroic rocks – the tale of microtextures

    University dissertation from Lund University, Faculty of Science, Department of Geology, Lithosphere and Biosphere Science

    Author : Victoria Beckman; Lund University.; Lunds universitet.; [2018-04]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zircon formation; metamorphism; prograde; gabbr; zircon; baddeleyite; zircon; baddeleyite; metamorphic; prograde; zircon textures;

    Abstract : Dating of metamorphic events is crucial for the understanding and reconstruction of large-scale geological processes such as orogenesis. Zircon is one of the most commonly used minerals for dating of igneous and metamorphic events. Zircon incorporates uranium and excludes lead during crystallization, and with time the uranium decays to lead. READ MORE

  5. 5. Palaeoenvironments, palaeoecology and palaeobiogeography of Late Cretaceous (Campanian) faunas from the Kristianstad Basin, southern Sweden, with applications for science education

    University dissertation from Lund University, Faculty of Science, Department of Geology, Lithosphere and Biosphere Science

    Author : Elisabeth Einarsson; Lund University.; Lunds universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; palaeoenvironments; palaeoecology; palaeobiogeography; Campanian; Kristianstad Basin; Teaching and Learning;

    Abstract : This thesis is thematically divided into two sections: Part1 presents studies related to the palaeoenvironments,palaeoecology and palaeobiogeography of the LateCretaceous (Campanian) faunas from the KristianstadBasin of southern Sweden; Part 2 reports on applicationsof palaeontological research for science education inschools.Part 1 was based on personally conducted fieldworkand biostratigraphical analysis at various Santonian-Campanian localities throughout Skåne.
