  1. 11. A comparsion of size fractions in faunal assemblages of deep-water benthic foraminifera : a case study from the coast of SW-Africa

    University essay from Lunds universitet/Geologiska institutionen

    Author : Oliver Björnfors; [2014]
    Keywords : Benthic; foraminifera; upwelling; size fraction; faunal assemblages; marine geology; Earth and Environmental Sciences;

    Abstract : Foraminifera are abundant in the marine sediment in all of the worlds’s oceans and offer a valuable proxy method to reconstruct water depth, circulation, productivity and deep water aeration. The choice of size fraction used when studying benthic foraminifera in upwelling areas are important. READ MORE

  6. 15. Sedimentology of the Bajocian Fuglunda Member at Eriksdal, Scania, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ingela Olsson; [1996]
    Keywords : Bajocian; Fuglunda Member; coal; cyclicity; grain size analysis; river processes; beach foreshore processes; interdistributary bays; lower deltaic plain; Earth and Environmental Sciences;

    Abstract : The Bajocian Fuglunda Member of Eriksdal consists mostly of sand, silt and coal arranged in cycles (2-4m). Each cycle generally starts with organic-rich heteroliths at the base and further up ripple-drift cross laminated and horizontally laminated fine sand follow. The coal seams at the top of the cycles are of minor thickness. READ MORE
