  1. 11. Assessing the biodiversity crisis within the Triassic-Jurassic boundary interval using redox sensitive trace metals and stable carbon isotope geochemistry

    University essay from Lunds universitet/Geologiska institutionen

    Author : Halla Margrét Viðarsdóttir; [2020]
    Keywords : Stenlille; Schandelah; redox conditions; C-isotopes; marine sediments; trace elements; enrichment factors; mass extinction; Triassic – Jurassic boundary; Earth and Environmental Sciences;

    Abstract : Around the Triassic-Jurassic-Boundary time interval, a severe mass extinction event occurred, which has been associated to volcanism of the Central Atlantic Magmatic Province (CAMP). Significant amounts of greenhouse gases as carbon dioxide (CO2) or methane (CH4) and other volatiles are suggested to have been released into the atmosphere, leading to global warming with subsequent impact on the biosphere.

  3. 12. Geochronology of gneisses adjacent to the Mylonite Zone in southwestern Sweden: evidence of a tectonic window?

    University essay from Lunds universitet/Geologiska institutionen

    Author : James Davies; [2020]
    Keywords : Geochronology; Hallandian orogeny; Mylonite Zone; Sveconorwegian orogeny; U-Pb; Idefjorden terrane; Eastern Segment; B-Bulan; Brobacka; Earth and Environmental Sciences;

    Abstract : The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. READ MORE

    Abstract : This report is partly written on behalf of and together with the County Board of Västernorrland and the Swedish Forest Agency of District Västernorrland, who wanted help to clarify two questions. The first question was about whether there have been any changes in how forest owners act when clear cutting riparian forests close to streams. READ MORE

  6. 15. Carbonate sedimentology and carbon isotope stratigraphy of the Tallbacken-1 core, early Wenlock Slite Group, Gotland, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jan Radomski; [2018]
    Keywords : Silurian; Gotland; Wenlock; carbon isotope stratigraphy; Slite Group; Hangvar Formation; sea level; carbonate platform; Earth and Environmental Sciences;

    Abstract : Den mer än 700 m mäktiga lagerföljden på Gotland är erosionsresterna av vidsträckta karbonatplattformar som bildades i den Baltiska bassängen under silurperioden. Detta arbete fokuserar på stratigrafin och bergarterna i borrkärnan Tallbacken-1 som togs upp vid Stora Vede av Sveriges geologiska undersökning år 2006. READ MORE
