【 摘 要 】

Analysis of localization of molybdenum mineralization within Ustynivka ore-bearing fields (Volyn block of Ukrainian shield) showed that the most beneficial is endo- and exocontact part of the same granite massif (it belongs to the Kyshynskyy complex), which forms a circular zone by the width from 300–500 m to 1–1,5 km, the total length is 40–50 km. Inside it are developed small intrusions, dykes and veins of ore-bearing rocks: small-medium and medium-leucocratic granite, granite porphyry and petrosilex porphyry, to varying degrees albitization and greisenization (up to the formation of late metasomatic products: alkaline metasomatites, beresits and greisens) that belongs to the second formation phase of Ustynivka granites. Today, within this zone there are found four molybdenum ore mineralizations of hydrothermal-greisen genetic type (molybdenum ore formation): Verbynskyy, Vysoke, Ustynivskyy and Richytskyy and several points of increased mineralization and geochemical anomalies. Mineralization represented by linear stockwork mineralized zones. By studying regularities of localization of molybdenum mineralization within ore-bearing fields and by features of material composition of ore-bearing rocks are formulated the main search criterias and features of molybdenum ores of this geological-formational type such as: tectonic, geological and structural, magmatic, hydrothermal-metasomatic, mineralogical, geochemical and geophysical.
