    • Environmental change in the Early Permian of NE Svalbard : from a warm-water carbonate platform (Gipshuken Formation) to a temperate, mixed siliciclastic-carbonate ramp (Kapp Starostin Formation) 

      Blomeier, Dierk; Dustira, Anna Marie; Forke, Holger; Scheibner, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      A detailed facies study of Early Permian strata within NE Svalbard reveals a fundamental change of the depositional setting, from a restricted-marine, warm-water carbonate platform to an open-marine, temperate-water, mixed siliciclastic-carbonate ramp. The uppermost strata of the Gipshuken Formation (Templet and Sørfonna members; Sakmarian–early Artinskian?) consist of microbialites (algal mats), ...

    • Permian depositional and environmental development in Svalbard 

      Dustira, Anna Marie (Doctoral thesis; Doktorgradsavhandling, 2013-10-31)
      The main objective of this thesis is to improve the knowledge on the depositional and environmental development of Svalbard during the Permian (299–252 Ma), with a primary focus on the Early to Late Permian Kapp Starostin Formation (Tempelfjorden Group). Thirteen localities of Permian sedimentary strata were investigated with respect to their sedimentological and geochemical properties. Sediments ...
