| 脉岩与脉状金矿：一个简要的评述 |
| |
| 摘 要： | 在综述了脉岩与热液型脉状金矿关系的基础上，认为中基性脉岩、煌斑岩脉不仅在空间上与脉状金矿相伴生，形成时间祁近，而且在物源和成因上有着密切的关联。脉岩是脉状金矿床成因系列的组成部分。据此提出中基性岩浆在某种动力作用下，诱导上覆花岗质岩石（包括古老变质岩）熔融，并发生混染，在地壳脉动作用下，脉岩与含矿流体多期次多阶段侵位，在相应的部位形成脉岩与矿脉共存的金矿区带。

| Abstract: | On the basis of the discussing the relationship between dykes andepithermal vein gold dcposits,it is considered that basic dykes and lamprophyric dyke notonly are associated with gold lodes in space and time, but also have a close relationshipwith gold deposits in material source and genesis.Dyke is a com ponent of the geneticseries of vein gold deposits. The upper granitic rocks concluding some metamorphic rockscould be melt and contaminated by the intrusion of intermediate-basic magma. Becauseof frequent crust movements,dykes and gold-bearing fluids emplace by multi-episodesand multistages.Therefore,the dykes and gold lodes are associated in the zone of golddeposits. |
