Magmatic Control of Gold Mineralization in Western Primorye

Abstract

The article analyzes the regional gravitational field of northeastern China, Korea, and Western Primorye. The distribution of gold deposits is compared with the development of Mesozoic magmatism and negative gravitational field anomalies. Based on an analysis of geological, minerogenic, petrophysical, and geophysical materials, geological and geophysical zoning of the western part of the Khanka massif was carried out and a scheme was compiled for interpreting geological and geophysical data with minerogenic elements. The authors have determined the relationship between magnetic and gravitational field anomalies and the position of prospective gold-bearing ore districts and clusters in the junction zone of the North China Triassic–Jurassic volcanoplutonic belt with Proterozoic substrates of the Khanka massif. Based on geophysical data, early Jurassic intrusions were identified, which controlled the location of gold ore clusters. A conclusion is drawn about the relationship between gold mineralization and Jurassic magmatism, which increases the prospects for discovering gold mineralization in the Prikhankaysky region of Western Primorye.
