摘要
矿区爆发角砾岩筒是一个含有富铜矿的大型水晶矿床。文章介绍了爆发角砾岩筒的规模、形态、产状、岩相分带、岩石类型以及岩筒内的水晶、铜矿的分布规律及其产出特征;论述了区域构造、矿区石英闪长岩体、次火山花岗斑岩体和爆发角砾岩筒的成因联系;对角砾岩筒的成矿控制条件及矿床成因进行了探讨。
The explosive breccia pipe in the Ermi Mine. Tonghua contains a largesize quartz crystal deposit associated With concentrated copper, The author describes in detail the size, shape, occurrrence, zoning of lithofacies, and rock type as well as distributional regularity of quartz drystal and copper in the pipe and charaeteristics of occurrence. Meanwhile, the author also describes the regional structure and original relationship between the quartz diorite body and subvoleanic granite—porphyry body and explosive breccia pipe. In addition, the author also made a preliminary study on ore—controlled condition for the breccia pipe by adoption of the concealed explosion theory related to magmatie activities.
