  2. 1. Assessing the reliability of detrital zircon in Early-Earth provenance studies

    Author : Ross Kielman; Martin Whitehouse; Alexander Nemchin; Victoria Pease; Marlina Elburg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geology; geologi;

    Abstract : Our understanding of the Early Earth and the processes that have shaped its evolution have spawned predominantly from the geochemical and isotopic signatures of a small number of zircon populations around the world. Studies of trace element distributions, Hf and O isotope systematics as well as mineral inclusion chemistry in detrital zircon are combined with U-Pb chronology in order to constrain source rock characteristics.

  4. 2. Origin of the Kleva Ni-Cu sulphide mineralisation in Småland, southeast Sweden

    Author : Karolina Bjärnborg; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoproterozoic; Fennoscandia; geochronology; geochemistry; sulphide remobilisation; gabbro–diorite; mantle; arc; ore genesis; Ni-Cu sulphide deposit;

    Abstract : The Kleva Ni-Cu sulphide deposit is situated within a gabbro-diorite intrusive complex in southeast Sweden. The basement north of the intrusive complex is dominated by 1.81–1.77 Ga granites of the Palaeoproterozoic Transscandinavian Igneous Belt (TIB). READ MORE

  5. 3. Proteomics of invasiveness of human breast epithelial cells

    Author : Kah Wai Lin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mechanisms of malignant transformation and cancer invasion and factors controlling them in response to various stimuli remain elusive. We used proteomics and systems biology to explore these mechanisms in human breast epithelial cells. The objective has been to identify a set of biomarkers for diagnostics and prognostics of breast cancer. READ MORE
