Mudrovs'ka I. The mineralogical-genetic model of gold mineralization in the Savran-Sinitsovska ore zone (Dnister-Bug domain, the Ukrainian Shield)

In the thesis the conditions of ore mineralization within lode-gold deposits of the Savran-Sinitsovska ore zone (Dnister-Bug domain of the Ukrainian Shield) are determinated. It is studied the sequence of metamorphic and postmetamorphic events and the place of ore mineralization within this sequence. The scheme of postmetamorphic paragenesises formation is created. The main physico-chemical properties of ore minerals, as were as relations between composition of ore paregenesises and wall-rock components are described. The main results of investigations are; the determination of composition of gold paragenesis; the character of gold precipitation conditions and the role of hexapyrrhotite/clynopyrrhotite transformation by ores formation. The complex of search criteria and gold mineralization features is established.
