It is distinguished that rocks of the Yamna formation of Paleocene age in the study area are characterized by different granulometric transitions. Within the rocks of the Yaremcha horizon cooper mineralization increase from the silt-pelites with clay-carbonate cement to anisomerous alevrite gravel polimicte sandstones on clay-cherty cement. The most amounts of chalcopyrite veins are found in the anisomerous weak sorted sandstones. Carried lithologacal-stadial and mineral-geochemistry investigations is result of the distinguishing two type of lithogenesis for the Carpathian region: 1) progressive lithogenesis including diagenesis processes, kata and metagenesis ones and 2) regression lithogenesis characterized by supergene processes and complicated by low-temperature hydrothermal processes. There are constant changes in temperature and pH-Eh environments during the transformation of sedimentary rocks. It is determined that in the Skyba zone at the base of Yamna formation of Paleocene there are the rocks of Yaremche variegated horizon with complex structures, cooper mineralization and is marker horizon between Upper Cretaceous and Lower Paleocene. For the first time based on the novel geoinformation technologies the geological-structural map of the Skyba zone of Flysh Carpathians is created and spatial connection between cooper mineralization manifestation and oil and gas deposits on the tectonic active area of structural zone is shown. Based on the own observations and on the analysis of the published materials for the first time the electronic data base of cooper mineralization for the Skyba structural zone is created. Keywords: Skyba zone of the Ukrainian Carpathians, sandstones, limestones, clays, marls, granulometric sorting of the rocks, mineral contents of the sedimentary rock cement, area of cooper mineralization.
