Abstract:
On the basis of the analysis of geological-geophysical materials in the Pribrezhnaya structural-lithologic zone, intrusive dome structures containing Late Cretaceous intrusive massif were identified. They incorporate ore fields of lead, zinc, silver, boron, tin, iron, manganese, gold, antimony, and fluorite deposits and ore occurrences belonging to different ore types. The regional distribution of endogenic ore mineralization is defined by specific features of the geological structure of the Pribrezhnaya structural-lithologic zone and by the activity stages of the strike-slip fault of the same name. The ore zonality of the magmatogenic-ore systems was determined by the PT conditions of mineral deposition. The established ore zonality and the polygenetic and polychronic nature of the ore-concentrating intrusive dome structures places doubt on the metallogenic specialization of multiphase intrusions of the East Sikhote Alin volcanoplutonic belt, which provides an opportunity to evaluate the prospects of the region from a new viewpoint.
