11. Urbanised Nature in the Past : Site formation and Environmental Developement in Two Swedish Towns, AD 1200-1800
Sammanfattning : In order to explore site formations and reconstruct environmental development in Medieval and Post-Medieval towns, urban occupational strata in Norrköping and Karlstad were studied according to biostratigraphy, sedimentology and pedology. New field procedures including continuous pilot sampling, parallel archaeological and geological stratigraphic interpretation, and on-site analysis of plant macrofossils were developed and applied at archaeological excavations in both towns.

12. Volcanic stratigraphy and hydrothermal alteration of the Petiknäs south Zn-Pb-Cu-Au-Ag volcanic-hosted massive sulfide deposit, Sweden
Sammanfattning : The Skellefte district is one of the most important mining regions in Sweden and Europe. The district contains more than 85 pyritic Zn-Cu-Au-Ag massive sulfide deposits. LÄS MER
13. Molecular, micro- and ultrastructural investigations of labile tissues in deep time
Sammanfattning : This thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods.

14. Revealing invisible strain : Magnetic Fabric Analysis as Strain Indicator in Analogue Models and Nature
Sammanfattning : Strain is accommodated by folding, thrusting and an “invisible” component, known as penetrative strain. Magnetic fabric analysis allows for identification and quantification of this imperceivable strain. In this thesis, magnetic fabric analysis is applied to quantify strain in analogue sandbox models.

15. Problems of stratigraphic correlation across the Arctic Ocean
Sammanfattning : Published articles on Arctic Ocean sedimentation rates generally falls into two categories; one suggesting mm/ka-scale sedimentation rates in the Amerasian Basin and the other cm/ka-scale rates in the Eurasian Basin. This is due to the interpretation of the first measured paleomagnetic polarity change in sediment cores as either the Brunhes-Matuyama (781 ka) reversal or as the short time magnetic excursion, Biwa II (220 ka) within the Brunhes Chron.
