STRUCTURAL POSITION OF GOLD ORE DEPOSITS IN THE INTRUSIVE VOLCANOGENIC FRAMING OF THE PRECAMBRIAN GONZHA SALIENT (UPPER AMUR REGION)

Abstract

Recent geological–geophysical studies of gold ore districts in the Russian Far East specified the essential role of Precambrian massifs, salients, blocks, deep faults, and protomagmatic chambers in distribution of noble metal deposits. However, additional information on position and major factors determining localization of explored deposits is needed to predict new objects in known ore districts and select the most promising ore occurrences. The analysis of geological data on the Gonzha area from this standpoint revealed that gold deposits in this area are associated with necks, stocks, sills, and paleovents located at the margins of volcanoplutonic granitoid massifs surrounding the local Precambrian salient.
