辽宁省红旗营子铅锌矿床岩脉与含矿构造关系研究

Research on the relationship between dyke in Hongqiyingzi Pb-Zn deposit in Liaoning province and the mineralized structure

文章通过野外对岩脉和含矿构造特征的观察研究,得出它们之间的先后顺序为:NE向花岗斑岩脉→闪长玢岩→矿化构造,NW向岩脉最晚。早期的NE向岩脉为成矿物质提供了运移通道和最佳的容矿空间,并表现为构造矿化带常沿着岩脉产出。

Observation and study on geological characteristics of dykes and mineralized structures in Hongqiyingzi Pb Zn deposit show the sequence of NE granite porphyry dyke→diorite porphyrite→mineralized slruclure→NW dyke. The early NE granite porphyry dyke serves as optimum transportation chan- nel of ore fluid and ore hosling space. On the spot of the deposit the structural-mineralized zones generally stretch along the early NE dyke.
