| 摘 要： | 海沟金矿区脉岩发育，主要类型有闪长玢岩、次安山岩、徨绿岩、正长闪长玢岩，按其与矿脉穿切关系划分为矿脉就位前脉岩、就位后脉岩，它们的地球化学特征表明这些脉岩具有良好的同源演化关系，它们不仅与成矿具有密切的时空关系，而且为金矿成矿带来成矿流体和部分成矿物质.

| Abstract: | Vein rocks are well developed in Haigou gold ore field,Jilin Province The main rock types are dioritic porphyrite,subandesite,lamprophyre and syenodioritic porphyry The vein rocks can be divided into two types,one emplaced before ore veins,and the other after the ore veins Geochemical characteristics of vein rocks show obvious evolution relationship,since they were derived from the same source They not only have closely temporal relationship with gold ore,but also provide space,ore forming fluids,and ore forming materials for gold ore |
