3. 22. The first study of the micro-fauna of middle Cambrian olistoliths in the Argentine Precordillera

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Elise Fahlgren; Maria Tranvik; [2015]
   Keywords : Olistolith; Burgess Shale-type preservation; middle Cambrian; Precordillera; Micropaleontology;

   Abstract : This study implies a survey of a somewhat unexplored Cambrian carbonate formation in the Argentine Precordillera (AP) located in western Argentina, close to the city of San José de Jáchal. The carbonate platform of the AP is a unique piece of the South American geology and is in this study partly surveyed and compared with the Stephen Formation of northern Canada, a middle Cambrian unit renowned for its contents of exceptionally well preserved soft bodied fossils named the Burgess Shale biota.

5. 24. Geophysical characterization and petrographic analysis of cap and reservoir rocks within the Lund Sandstone in Kyrkheddinge

   University essay from Lunds universitet/Geologiska institutionen

   Author : Mikael Jakobsson; [2014]
   Keywords : wire-line logging; Lund Sandstone; natural gas storage; Scania; Reservoir rock; reservoarbergart; borrhålsloggning; Lundasandstenen; naturgaslager; Skåne; Earth and Environmental Sciences;

   Abstract : Geophysical investigations in the Kyrkheddinge area including seismic surveys and wire-line logging were carried out by Swedegas AB between 1978-1985. This study has used the data to make a geophysical and petrographic characterization of cap-rock and reservoir sections within the Lund Sandstone in Kyrkheddinge to evaluate the conditions for storing gas in the bedrock.

6. 25. Identifying the Cretaceous–Paleogene boundary in North Dakota, USA, using portable XRF

   University essay from Lunds universitet/Geologiska institutionen

   Author : Emilie Larsson; [2013]
   Keywords : geokemi; K–Pg gränsen; portabel XRF; North Dakota; K–Pg boundary; portable XRF; terrestrial deposits; geochemistry; terrestra avlagringar; Earth and Environmental Sciences;

   Abstract : En portabel röntgenfluorescens (XRF) spektrometer användes i denna studie för att identifiera kemiska markörer relaterade till Krita–Paleogen (K–Pg) gränsen i North Dakota, USA. Vid K–Pg-gränsen träffades jorden av en asteroid vilket resulterade i ett av de fem stora massutdöendena. READ MORE
