摘要
脉岩与金矿床有着密切的成生关系,正确认识二者的相互关系,能有效提高找矿效果。三合屯矿区成矿期的闪长岩脉与金矿体在时空上紧密伴生,赋存于北东向同一构造系统,贯穿于金矿化的整个过程,为金矿体的形成提供物源及热源。类比区域金矿床闪长岩脉与矿体的分布关系,可做为区域找矿勘查的重要标志,降低勘查过程中的盲目性。
Vein rock and gold deposit have a close generative relationship,and a correct understanding of the mutual relationship between them can effectively improve the ore prospecting effect.The diorite dikes and gold ore bodies in the ore-forming period of Sanhetun mine area are closely associated in time and space.They occur in the same tectonic system in the northeast direction and run through the whole process of gold mineralization,providing source and heat for the formation of gold ore bodies.The analogy between the distribution of diorite dikes and orebodies in regional gold deposits can be used as an important symbol for regional prospecting and reducing the blindness in the exploration process.
