Abstract

In Poland successfully operating the same type of deep-seated deposits of copper sandstones and shales, which play an important role in the economy of the country. In addition to copper, is extracted silver and other metals. For the area of Lower Silesia (Poland) are typical of the deposits occurring among the sediments of the Permian age and mainly formed under the conditions of arid lithogenesis. The highest value for the containing copper mineralization precipitation have lagoon and shallow marine intertidal facies. Localization of the deposits was done naturally, which is reflected by consistency stretch of ore bodies, their confinement to certain stratigraphic horizons and facies. The most important ore minerals are bornite, chalcocite, chalcopyrite. The article describes the Genesis of similar deposits of copper sandstones and shales of Poland on the example of mine “Ore”. The authors selected samples of productive horizons at depths 1078,7 m and spent their detailed mineragraphy study. The generalization of the results of sampling and geological environment, analysis of existing ideas about the formation of deposits clearly indicate stratiforme-sedimentary Genesis of the mineralization. The authors do not exclude that the deposition of copper might occur and hydrogen sulfide syngenetic barriers resulting from the activity of sulphate-reducing bacteria. This is evidenced by spherical formations made digenite and chalcocite. The genetic model is evidenced by the successful exploitation of deposits of Poland, what to consider when preparing for the exploitation of deposits of this type in Russia.
