Аннотация

Subjects of research: the gold-sulphidc-arscnious deposit of Daughyztau in Western Uzbekistan. Purpose of work: studying Au-forms, the typomorphic peculiarities of pyrite and arsenopyrite in the primary ores for development of prospectingestimating critcrions for the gold ores of daughyztau type. Methods of research: traditional methods of a mineralogical investigation, EMP and XR-structural analyses. The results obtained and their novelty: 1) a number of new minerals were established for the first time for the deposit; 2) the typomorphic crystallochcmical peculiarities of the pyrite and arsenopyrite were investigated; 3) the new morphotypcs of the productive sulphides and Au-content in them were studied; 4) the mctamorphogcnic-hydrothcrmal pyritc-sulphoarscnidc microassociation was detected; 5) prospecting-estimating critcrions for the gold orcs of daughyztau type have been elaborated. Practical value: the results of the investigation can be applied into the practical activity of geological exploration and as a basis for the development of the method of refractory ores dressing. Degree of embedment: the results of the research have been given to SE SIC “The geology of precious and colored metals”, SE “Daughyztau GE” and IMR for a practical appliance Field of application: geology branch of science and production.
