1. 1. Permeability variation in a tidal Jurassic deposit, Höganäs basin, Fennoscandian Border Zone

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Henrik Jonsson; [2002]
   Nyckelord :permeability; Höganäs Formation; anisotropy; heteroliths; Lower Jurassic; quartz cement; Earth and Environmental Sciences;

   Sammanfattning : An examination of permeability differences was made on plugs obtained from six drill cores in both horizontal and vertical directions, representing different facies of the Hettangian strata from the Höganäs Formation. The permeability analyses distinguish permeability differences from anisotropy and an index was created to evaluate the anisotropy. LÄS MER

3. 2. Sedimentology of the Bajocian Fuglunda Member at Eriksdal, Scania, southern Sweden

   Magister-uppsats, Lunds universitet/Geologiska institutionen

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

   Sammanfattning : 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. LÄS MER
