  1. 1. Impactites from the Hiawatha crater, North-West Greenland

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Jacob Gustafsson; [2020]
    Nyckelord :Hiawatha; impact crater; Cape York; Baffin Bay; Greenland Ice Sheet; Younger Dryas; meteorite; impactite; organic carbon; conifer; vitrinite reflectance; Ro; cellular texture; chromite; chromium isotope; toasted quartz; ballen quartz; melted carbonate; granular zircon; planar deformation feature;

    Sammanfattning : The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. LÄS MER

  2. 2. Maturity of kerogen, petroleum generation and the application of fossils and organic matter for paleotemperature measurements

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Yaser Abdullah Abdullah Al-Mashramah; [2011]
    Nyckelord :thermal alteration; thermal maturation; kerogen; petroleum generation; paleothermometres; vitrinite; conodonts; graptolites; palynomorphs; Earth and Environmental Sciences;

    Sammanfattning : The origin, composition and maturity of kerogen, and its conversion to petroleum is reviewed. Various methods for estimating the maximum temperature to which kerogen and potential source rocks were subjected are also reviewed. LÄS MER
