GEOCHEMICAL PREREQUISITES AND THERMODYNAMIC CONDITIONS FOR GOLD MINIRALIZATION LOCALIZATION OF THE NORTHEASTERN SLOPE OF THE YENISEI RIDGE

Фисенко В.Г., Макаров В.А.
Gathering, analysis and generalization of geology and gold mineralization information of the northeastern slope of the Yenisei Ridge was carried out. Metallogenic scheme of the investigated area was built. Prospective gold mining areas and ore-geochemical zones were identified. The characteristics of geochemical fields of the host rocks and near-ore changes within the three zones of gold potential ore clusters (Nigne-Chirimbensky, Vangashsky, Iochiminsky) were described. The composition of ore-bearing fluids and thermodynamic conditions of the ore process are defined by the study of gas-liquid inclusions in quartz from the studied ore clusters. Temperature and pressure gradual decreasing in ore-bearing solutions at a distance increasing of objects to the east of the area from granitic intrusions and deep fault Ishimbinski is shown. Recommendations for gold ore prospecting are given.
