Modeling spatial and genetic associativity of Fe–Mn–Au-bearing ore deposits

The authors have been studying geology of gold and quartz deposits in the Urals for a long time, and have collected an extensive evidence on the formation of gold ore bodies and quartz veins for the assessment of gold mining expediency in mined-out fields. In terms of Shabrovsky mine field, the special and genetic associativity of gold mineralization and iron–manganese–gold formations is demonstrated. Physicochemical modeling with regard to geodynamic situations and geological structure evolution in Shabrovsky mine field allows correlating formation of ferruginous, manganese and gold-bearing metasomatic rocks with time and space development of the unified ore-geochemical hydrothermal system under the drive forces of regressively alternate pressure and temperature. In Shabrovsky mining area, in the zones of quartzite and gondite, some sites are detected, with sizes and gold contents meeting the modern demands of the industry. The aforesaid offers grounds for auditing gold reserves in bodies of ferruginous quartzite, gondite and rhodonite, appraisal of ornamental raw material in the latter.
