论述了珲春东部金铜钨矿带成矿地质条件,认为下古生界志留系下统五道沟群变质岩,印支—燕山期杂岩体是金铜钨的成矿主要矿源体;分析了典型矿床杨金沟白钨矿床的成因机制,确定为层控与岩浆热液复合型白钨矿床;指出成矿带下段找矿思路。
The authors discuss the metallogenic geological conditions of the gold Cu-Cu ore belt in the eastern Hunchun, and consider that the Lower Paleozoic Silurian is the Wudaogou Group metamorphic rocks. The Indosinian-Yanshanian complex is the main ore-forming body of gold, copper and tungsten. The formation mechanism of the Yangjinou scheelite deposit in a typical ore deposit is analyzed. It is determined to be a stratiform control and magmatic hydrothermal compound type scheelite deposit. The ore prospecting thought of the lower part of the metallogenic belt is pointed out.
