Main features of structure, mineralogy, genesis and prospectivity of Zidarovskoye gold-copper-polymetallic deposit (NRB)
Abstract
The geological structure and structure of the Zidarovskoye deposit are considered. Types of ores and near-ore metasomatites are described, their composition and sequence of mineral formation are characterized, concentric zonality of development within the deposit is revealed. Genetic connection of near-ore feldspatolites and propylites with copper-bismuth ores and berezites with gold-silver-polymetallic ores was established. Two gold-producing paragenesis were revealed: gold-chalcopyrite-sphalerite and gold-chalcopyrite-galenite; the latter is of industrial importance. The characteristic of morphology, size, composition and conditions of localization of nugget gold in ores is given. It is established that zonality of gold individuals reflects the regular change of its assay in gold-silver-polymetallic ores. Practical recommendations regarding prospectivity and local forecasting of gold mineralization of the deposit are made.
