Bibliographic description: Galyamov, A.L., Volkov, A.V., Lobanov, K.V. Geophysical model of the Earths crust, geodynamic conditions and prospects for the discovery of Pb-Zn deposits in the Russian Arctic. Arctic: ecology and economy, 2020, no. 3(39), pp. 87-98.

The article discusses the results of a comparative metallogenic GIS analysis based on GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) data that allows the use of elements of the deep crust structure as global features in forecast and prospecting models of Pb-Zn deposits. Through the GIS analysis the authors have identified the main global features: the spatial distribution of MVT-type deposits coincides with the asthenospheric uplifts of the MOHO discontinuity; deposits are confined to the medium-temperature region of the upper mantle and are controlled by deep deflections of the crust sedimentary layer, identified by seismic velocities; the VMS-type deposits, located mainly on a thin sedimentary crust, correlate with moderate thickness of the lower crust; the SEDEX-type deposits, which occupy an intermediate position between MVT and VMS, are controlled by thin and/or moderately thick sedimentary crust in the areas of rift development. The use of these global features in forecast and prospecting models is to identify new promising areas in the Russian Arctic zone for predicting new Pb-Zn deposits.
Keywords: Arctic zone of Russia, crust, deep structure, tectonic environment, deposit, MVT, SEDEX, VMS, lead, zinc, model, forecast, prospecting.
