NEW PROMISING MINERALIZED ZONES AND DEPOSITS OF THE NORTHWESTERN FLANK OF THE GEDEBEY ORE DISTRICT

Geological exploration and scientific investigations in the Gedebey deposit are clarified that deposit is a part of the epithermal system which belong to high sulfidation type with Cu-Au-Ag ore mineralization. Discovering of Gadir low sulfidation deposit with Au-Ag-Zn-Pb ore mineralization gives background to think about the existence of porphyry system near Gedebey deposit. The results of exploration in northwestern flank show that the most of alterations which related with ore mineralization are located along the Gedebey-Bittibulag deep fault. Several mineralization areas are located on this deep fault. The zoning alteration from northwestern flank area is determined by: the variation of the composition in the magmatic intrusions, the variation of the physicochemical conditions in the mineralization periods specific to the two magmatic chambers. In the East part of the area alteration is associated with the porphyry quartz-dioritic stock. The surface and subsurface alterations are associated with eruptionbreccia pipes in northwestern flank.
