TECTONICS AND PETROLOGY OF THE PETROVO-HNUTOVIAN ORE CLUSTER OF THE NEAR-AZOVIAN MEGABLOCK OF THE UKRAINIAN SHIELD

摘要

The results of the investigations for the large structural Petrovo-Hnutivian ore knot within the Near-Azovian megablock of the Ukrainian Shield are considered. The features of fault-block tectonics and its influence on the forming ore knot are defined. The Kalmius', Oktiabrsk's and other fault zones of the orthogonal and diagonal systems and their significance in the localization of metasomatites and exceptional ore-bearing fluorite-parisite rare-earth dyke are characterized. The mineral composition of dyke is analyzed.
