1. 11. 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. 12. Petrology and depositional history of the Campanian strata at Maltesholm, Scania, southern Sweden

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Olof Sandström; [1994]
   Nyckelord :Kristianstad basin; Maltesholm; Campanian; grainstone; facies; storm sediments; hummocky cross bedding; conglomerates; shallow marine environment; rudists; belemnites; Earth and Environmental Sciences;

   Sammanfattning : Campanian sediments of the Maltesholm quarry consist of mostly coarse grained, poorly consolidated, ruditic grainstones, almost free of micrite and lime mud, with interbedded clay horizons. The main constituents of the grainstones are coralline algae and quartz. LÄS MER
