许多内生金属矿床,特别是热液矿床常与煌斑岩脉有着密切关系。矿脉可产于煌斑岩脉近旁,或者沿与煌斑岩脉同一系统的断裂产出。在找矿勘探工作过程中,研究煌斑岩脉的产状及分布,对于指导找矿及阐明矿床的形成过程具有一定的意义。笔者试就粤东地区某锡、铅、锌矿区所获点滴资料来谈谈煌斑岩脉的产出特征及其找矿意义。
Many endogenous metal deposits, especially hydrothermal deposits, are often closely related to lamprophyre dikes. The veins can be produced in the vicinity of the lamprophyre or in the same system as the lamprophyre vein. In the process of prospecting and exploration, studying the occurrence and distribution of lamprophyre veins is of great significance for guiding the prospecting and elucidating the formation process of the deposit. The author tries to talk about the output characteristics of the lamprophyre dikes and the significance of prospecting on the drip data obtained from a certain tin, lead and zinc mine in eastern Guangdong.
