The ore object has Proterozoic age and belongs to gold quartz – low-sulfide formation. Basis of its structure and a standard geological situation of ore veins location are fault paragenesis that had arisen in process of development big fault zone during the Ebourneisky tectonic and magmatic cycle. This object belongs to a formation typical for the metallogeny of zones green of belts of ancient shields and has good prospects of accumulation of the ore resource potential.

The current study presents a numerical model for microbially induced calcite precipitation predicting the reduction of permeability over time due to biomineralization in fracture of rocks and prevention of a leakage from CO2 storage reservoirs.
