The Swedish Museum of Natural History is a government agency with a mandate to promote knowledge, research and interest in our world. It is a prominent research institution and Sweden's largest museum. For more than 200 years, the museum has been collecting specimens and data and conducting research on life on earth. The collections contain more than 11 million plants, animals, fungi, environmental samples, minerals and fossils. All research and knowledge are shared in the exhibitions, Cosmonova and in activities at the museum and digitally. Applications are invited to a 2-year postdoctoral research position related to a Swedish Research Council funded project Early earth evolution from the first continents to the first life – a microanalytical perspective. The purpose of this field- and laboratory-based project is to is to investigate the Eoarchean gneiss complexes of northern Labrador, Canada and southern west Greenland, some of the most extensive >3.6 Ga regions on the planet, to (1) better constrain the timing of formation and subsequent evolution of the earliest crust preserved on Earth, (2) document the earliest stages of the irreversible differentiation of crustal and mantle geochemical and isotopic domains and (3) test whether any early supracrustal assemblages within these gneiss complexes are truly ancient. The project will utilise novel and innovative high-spatial resolution ion microprobe-based methods, using the CAMECA ims1280 instrument in the NordSIMS facility at the Swedish Museum of Natural History as well as complementary microanalytical facilities at collaborating institutions (University of Western Australia, Polish Academy of Sciences). 1 job(s).
