1. Investigation of Thermal Maturity of Organic Matter at the Cambro Ordovician Transition in the Zagros Basin, Iran
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The thermal maturity of sediments from the upper Cambrian to lower Ordovician Mila and Ilbeyk formations in the Zagros Basin in southwestern Iran is evaluated in this thesis. A number of low-cost, fast, optical evaluation methods are utilised to assess their effectiveness for providing accurate, well constrained thermal maturity results. READ MORE

2. The Eemian Baltic Sea hydrography and paleoenvironment based on foraminiferal geochemistry
University essay from Lunds universitet/Geologiska institutionenAbstract : I den här masteruppsatsen undersöktes geokemin i kalkskalen av bottenlevande foraminiferer från Anholt (Kattegat), Ristinge (Bälthavet) och Obrzynowo (Egentliga Östersjön), för att rekonstruera de hydrografiska förhållanden i Östersjön och paleomiljön under den senaste interglacialen (130 - 115 ka BP). De variabler som analyserades innefattade Mg/Ca, Ba/Ca och Mn/Ca samt stabila syre- och kolisotoper (δ18O och δ13C) i kombination med data från tidigare studier och modern hydrografi. READ MORE

3. Ancient DNA in paleosols, SW Greenland : A tool for retrospective paleoenvironmental studies?
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Ancient DNA (aDNA) is a useful tool for retrospective paleoenvironmental studies. Paleosols formed in Arctic environments constitute a potential archive of aDNA from terrestrial organisms living in past environments, given that the cold and dry climate prevailing at high latitudes favors DNA preservation and hamper post-depositional mobility of deposited fragments.

4. The Sedimentological Distribution of Upper Brent, Oseberg field, North Sea
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Oseberg hydrocarbon field is located in the northern North Sea sedimentary basin (61-62° N) on the eastern flank of the Viking Graben and is bounded to the east by the Horda Platform and the Øygarden Fault Complex (ØFC). The field is covering up most parts of block 30/6 and 30/9 on the Norwegian Continental Shelf (NOCS) but also minor parts of blocks 30/5, 30/8 and 30/12. READ MORE

5. The paleoceanography of Kattegat during the last deglaciation from benthic foraminiferal stable isotopes
University essay from Lunds universitet/Geologiska institutionenAbstract : En borrkärna från Anholt (Kattegatt) togs upp under IODP-expedition 347 i Östersjön. Kärnan är daterad till ~18-14 ka BP och representerar deglaciationen i slutet av Weichselistiden. READ MORE
