Reconstruction of the ore-forming system in the Mnogovershinnoe gold-silver deposit (Lower Amur River Region) based on the structure of ore-bearing zones and isotopic studies

摘要

The hydrothermal ore-forming paleosystem of the Mnogovershinnoe deposit is reconstructed by defining lithothectonic elements constituting ore-bearing zones with account for their formation mechanisms and positions in the conditional geochronological scale of the hydrothermal activity and isotopic data. The use of lithotectonic elements for deciphering ore genesis events made it possible to take into account both synchronously and successively formed parts of ore bodies, which substantially improved the quality of the reference data for developing a dynamic model of the deposit. The approach proposed for reconstructing the hydrothermal paleosystem of the Mnogovershinnoe deposit may be used for developing models of other ore objects.
