As a result of analytic and microscopic examination of collected materials Gizilbulaq ore deposit the following mineral associations have been separated: quartz – pyrite, quartz – pyrite – chalcopyrite, quartz – chalcopyrite, quartz -carbonate. All mineral associations included gold, but in various ore types the quantity of gold, its discontinuity forms, relationship with sulphide minerals and their sizes are different.
Slitedispersion gold – quartz – pyrite state comparatively easily observed under the microscope is in connection with the hister ore deposition process quartz – pyrite- chalcopyrite, namely quartz – chalcopyrite and quartz – sphalerite ore types of roughdispersion and the gold which has large sizes form.
In considered mineral associations the size of gold inclusions range within 0.01-0.03 mm.
