1. 6. The first study of the micro-fauna of middle Cambrian olistoliths in the Argentine Precordillera

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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.

3. 7. Linguliform Brachiopods from the Middle Cambrian ‘Thick’ Stephen Formation at Odaray Mountain, Canadian Rocky Mountains

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Sara Saxén; [2015]
   Nyckelord :Brachiopoda; Lingulida; Middle Cambrian; Stephen Formation; new species; Brachiopoda; Lingulida; Mellersta kambrium; Stephenformationen; ny art;

   Sammanfattning : The linguliform brachiopod fauna from the Stephen Formation have long been thought to be very species poor and only consist of a few genera, but new discoveries from lime-stone beds in the “thick” Stephen Formation shows that this is not the case. The species described herein, Kyrshabaktella cf. tatjanae and Ceratreta hansi sp. nov. LÄS MER

4. 8. Från hav till land : en geologisk beskrivning av Skrylle

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Nyckelord :Lund; Skrylle; Hardebergasandsten; diabasgångar; kambrium; perm; Hardeberga Formation; dolerite dykes; Cambrium; Earth and Environmental Sciences;

   Sammanfattning : Skrylle is a popular recreation area situated between Södra Sandby and Dalby in the Municipality of Lund. It covers an area of roughly 27 km2 and comprises 10 reserves and one national park, Dalby Söderskog. The area presents a mixture of forests and pastures on the northwestern part of Romeleåsen.

5. 9. Alunskiffern i Östergötland : utbredning, mäktigheter, stratigrafi och egenskaper

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Fredrik Svantesson; [2013]
   Nyckelord :Östergötland; biogen gas; alunskiffer; kambrium; ordovicium; stratigrafi; petrologi; geokemi; petroleum; uran; Earth and Environmental Sciences;

   Sammanfattning : The alum shale has for centuries been of interest and was an important resource in Sweden's early industrial history through the manufacturing of alum - a potassium aluminium sulfate. In addition to describing the chemical properties this paper also include a brief description of some of the chemical processes that are responsible for the enrichment of oil, gas and uranium.

7. 10. Alunskiffer på Öland : stratigrafi, utbredning, mäktigheter samt kemiska och fysikaliska egenskaper

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Niklas Brådenmark; [2013]
   Nyckelord :Alunskiffer; shale gas; Öland; biogenic gas; alum shale; cambrian; kambrium; biogen gas; skiffergas; Earth and Environmental Sciences;

   Sammanfattning : Sammanfattning: Utvinning av naturgas ur skiffer ses sedan början av 2000-talet som en energikälla med växande potential på flera håll i världen. Den öländska alunskifferformationen har undersökts för att utreda om det finns naturgas att utvinna även här. LÄS MER
