Vendian and paleozoic accretionary history of high arctic - polar urals, novaya zemlya, and taimyr


Research objectives and content
The High Arctic is a key link in the plate tectonic evolution of northern Eurasia. Results from this investigation will lead to i) a model for the tectonic evolution of the High Arctic, and ii) model integration with existing scenarios for the tectonic evolution of northern Eurasia and the northern Atlantic region. These objectives will be achieved with field-work (mapping and structural analysis) and geochemical analysis (elemental and isotopic) in the Polar Urals (to characterize the composition and age of the volcanic and ophiolitic sequences present, correlate them where possible, and characterize their basement), in Taimyr (to determine the time of suturing of the thrust- bounded terranes), and in Novaya Zemlya (to understand the relationship between the Baikalian orogeny and thrusting). The resulting structural, geochemical, and geochronological data will enable me to determine the tectonic provenance of the accreted terranes, reconstruct the tectonic history of the Polar Urals, and compare this evolution with existing models for northern Eurasia and possibly the northern Atlantic region. The geochemical techniques (both conventional and innovative high-resolution ion-probe) to be used include XRF for major and trace elements, IDMS for REEs, and conventional mass spectrometry for Rb/Sr, Pb/Pb, U/Pb, and Sm/Nd. Plagiogranites, xenoliths, and migmatites will be analyzed using the Cameca 1270 ion-probe at LIG.
Training content (objective, benefit and expected impact)
Objectives: 1) To increase and broaden existing geologic and geochemical skills. 2) To acquire new knowledge of state-of-the-art, high resolution ion-probe technology using the Cameca 1270 (in Stockhom), the only high resolution ion-probe of its kind in Europe. Benefits and impacts: i) A deeper and expanded knowledge of geologic and geochemical process, in creating a better- rounded and more versatile geologist, improves and increases the scientific potential of the EC and associated states; ii) gaining technical skill with state-of-the-art equipment, whose application will be expanding in the future, improves and increases the scientific potential of the EC and associated states; and iii) the results of this project, being of interest to an international community, will facilitate other research within the EC and around the world.
Links with industry / industrial relevance (22)
In Russia: the Ministry for Natural Resources (Dr. A. Morozov), the Russian Academy of Sciences (Director Y. Leonov), and the Norilsk Mining Company. In the EU: the EUROPROBE programs TIMPEBAR and URALIDES (results from this project will be integrated with existing data from these programs).
