  1. 1. Multistressors Related to Climate Change and Their Effects on Global Biodiversity during the Cenozoic Age

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Robin Mårtensson; [2018]
    Nyckelord :multistressors; biodiversity; paleontology; Paleocene; Eocene; Oligocene; Miocene; Pliocene; Pleistocene; sea level; deep ocean temperature; sea surface temperature; carbon dioxide; foraminifera; ocean circulation; Cenozoic; paleoceanography; climate change; Earth and Environmental Sciences;

    Sammanfattning : As multistressors have been shown to have significant effects on biodiversity and ecosystem functioning, the following study was made with the purpose of examining how a number of stressors specifically connected to climate change may have varied during the latest 65,5 million years and whether it is possible to predict potential effects on global biodiversity in the future. The analyses focused on global species richness during the Cenozoic age along with variables such as variations in atmospheric CO2, sea surface temperatures and global sea levels derived from analyses of various stable isotopes found in marine sediments.

  3. 2. Cenozoic history of North Atlantic deep sea carbonate preservation

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Marcus Länje; [2015]
    Nyckelord :Carbonate compensation depth; CCD; IODP; ODP; DSDP; Atlantic Ocean; subsidence modeling; Cenozoic; database of sediment lithologies; Google Earth;

    Sammanfattning : Carbonate preservation in the oceans occurs at a depth called the carbonate compensation depth (CCD). The CCD is where the input rate of carbonate from the surface of the ocean is balanced by the dissolution rate. LÄS MER

  4. 3. Palynological investigation of coal-bearing deposits of the Thar Coal Field Sindh, Pakistan

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Pardeep Kumar; [2012]
    Nyckelord :hydrocarbons; Eocene; Paleocene; pollen; coal; Pakistan; palynofacies; Earth and Environmental Sciences;

    Sammanfattning : Palynologiska och sedimentologiska studier av prover från en borrkärna från Thar-kolfältet (nedre Indus Bassängen), Pakistan har genomförts. De kenozoiska sedimenten ligger på det granitiska urberget (som utgör den Indiska skölden) och utgörs främst av kolavlagringarna vilka är mellanlagrade av sandsten och silt-sten.. LÄS MER

  5. 4. Petroleum Geology of the Barents Sea

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ian McGimpsey; [2008]
    Nyckelord :petroleum geology; geography; geology; Barents sea; geografi; geologi; petroleum geologi; Barents hav; Earth and Environmental Sciences;

    Sammanfattning : The purpose of this publication is to outline the exploration history and development of the Barents Sea region. It is intended as an overview of the region, summarizing the various basins, reservoirs, trap systems, and source rocks. Exploration of the Barents Sea began in the 1970s and major discoveries took place in the 1980s. LÄS MER

  7. 5. The Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones of the East European Craton : geomorphology, architecture of the sedimentary cover and the crystalline basement

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Dzmitry Kurlovich; [2007]
    Nyckelord :the Polotsk-Kurzeme Deformation Zone; the Småland-Blekinge Deformation Zone; GIS; fault; tectonic activity; geomorphology; sedimentary cover; Polotsk-Kurzeme deformationszonen; Småland-Blekinge deformationszonen; förkastning; tektonisk verksamhet; geomorfologi; sedimenttäcket; Earth and Environmental Sciences;

    Sammanfattning : This is a study of the influence of the crystalline basement faults of the Polotsk-Kurzeme and the Småland-Blekinge Deformation Zones on the development of the sedimentary cover and the formation of the present topography. The purpose is to define the character and possible causes of this influence. LÄS MER
