摘要
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 paper discussed the ore-forming geological conditions of Au-Cu-W ore belt of eastern part of Hunchun, it is considered that metamorphic rock of Wudaogou Group, lower Paleozoic Silurian period, Indo-Chinese- Yanshanian complex body is a main source rock of Au-Cu-W, meanwhile, analyzed the formation mechanism of Yangjingou scheelite deposit, which belongs to composite stratabound and magmatic hydrothermal scheelite deposit, and pointed out prospecting ideas in the lower of the metallogenic belt.
