  1. 1. Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Anna Stella Guðmundsdóttir; [2021-03-18]
    Keywords : ;

    Abstract : The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing Firkanten Formation, has been the subject of study for researchers in the past but little focus has been on the northeast edge of the basin until now. Due to the economic potential of the coal seams in the formation, the Norwegian mining company, Store Norske Spitsbergen Grubekompani (SNSG), has for several years conducted core drilling in key locations in basin, and for decades, they have given an access to their core material to researchers.

    Author : Fredrik Lindgren; [2019]
    Keywords : Brownification; DOC; dissolved iron; humic lakes; sulphur deposition; absorbance; climate change;

    Abstract : During recent decades many lakes have become browner in the northern hemisphere and more specific in Sweden. This process is called brownification. Brownification of lakes makes it more difficult to clean water to drinking water and may have negative ecological effects on biota. READ MORE
