鸡东金场沟铜钼、金矿化区控矿条件与找矿方向

经对黑龙江鸡东金场沟矿区地层条件、构造条件和次火山侵入岩条件的分析, 指出环形构造控制着与成矿有关的次火山侵入岩和角砾岩筒的分布, 角砾岩筒构造控制着铜钼矿体的产出。区内银金矿的形成与石英闪长岩有关, 而铜钼矿的成矿作用与花岗斑岩有关。在控矿条件分析的基础上建立了本区的铜钼多金属成矿模式, 指出了找矿方向。

Ore controlling conditions and prospecting direction for Jinchanggou copper-molybdenum-gold m ineralization area in Jidong

Based on the analysis of stratigraphy, tectonics and sub-volcanic intrusive rocks in Jinchanggou mining area of Jidong in Heilongjiang, the authors suggest that the circular structure controled the distributions of sub-volcanic intrusive rocks and breccia pipe which relative to mineralization, and the breccia pipe controled the production of copper-molybdenum orebody. The formation of silver-gold deposits and copper-molybdenum deposits have relation to quartz diorite and granite porphyry respectively. Metallogenic model of copper-molybdenum poly-metallic deposit is established on the basis of ore controlling conditions analysis, and the authors point out the prospecting direction.
