【摘要】：涞源杂岩体是中国东部燕山期岩浆岩带的重要组成部分,其成矿作用强烈、成矿作用方式多样,许多矿产地矿床类型为斑岩型、矽卡岩型、热液型等"多型一体",成矿元素Mo、Cu、Fe、Pb、Zn、Au、Ag等共伴生。该杂岩体内已查明大型矿产地4处、中型矿产地5处,是河北省有色金属的主要集聚区。高侵位的超浅成闪长玢岩、流纹斑岩等小岩株控制了斑岩型铜钼矿,中深成中酸性侵入岩与矽卡岩型、热液型铁铜铅锌金等多金属成矿关系密切,断裂构造、接触带构造是主要的控矿构造,赋矿围岩对成矿有一定的控制作用,钙矽卡岩与铜矿、镁矽卡岩与铁铅锌矿多金属关系密切。同时,本文对斑岩型、矽卡岩型、热液型-矽卡岩叠加型、热液型等典型矿床特征进行了综述,并指出了今后涞源杂岩体的找矿勘查方向。
[Abstract]:Laiyuan complex is an important part of Yanshanian magmatic belt in eastern China. Its mineralization is strong and metallogenic in various ways. Many mineral deposit types are "multitype" such as porphyry type, skarn type, hydrothermal type and so on, accompanied by metallogenic elements such as Mo,Cu,Fe,Pb,Zn,Au,Ag. Four large and five medium-sized minerals have been identified in the complex, which is the main accumulation area of non-ferrous metals in Hebei Province. The ultra-shallow diorite, rhyolite and other small rock strains with high emplacement control the porphyry copper-Mo ore. The intermediate-deep intermediate-acid intrusive rocks are closely related to skarn type, hydrothermal iron, copper, lead, gold and other polymetallic mineralization. Fault structure and contact zone structure are the main ore-controlling structures, ore-bearing surrounding rocks have a certain control effect on mineralization, calcium skarn and copper ore, magnesium skarn and iron-lead-zinc deposits are closely related. At the same time, the characteristics of typical deposits such as porphyry type, skarn type, hydrothermal skarn superimposed type and hydrothermal type are reviewed, and the prospecting and exploration direction of Liyuan complex in the future is pointed out.
