Abstract:
Nature and origin of submarine highs in the Arctic are considered to be one of the main issues of the evolution of the Artic Ocean. Rock bottom material were dredged on 4 sites in the area of the Mendeleev Rise during the Arctic-2012 expedition [Morozov et al., 2013]. Rock magnetic studies of the samples, which are mostly presented by igneous rocks, have been performed in order to find out any connection to their continental or oceanic origin. These first results have been partially correlated with paleomagnetic pattern of sedimentary cores from the same sites and region.
