摘　　要：依托《贵州省贞丰县水银洞金矿区中矿段勘探地质报告》建立的国内第一座原生卡林型金矿山“贵州紫金水银洞金矿”,历经多年开发,采矿权范围内主要探明层状似层状碳酸盐岩型资源即将耗尽,推断零星碎屑岩(报告中的钙质砂岩型)矿体成为矿山探矿提级增储的主要目标,基于生产实践中发现推断的碎屑岩型矿体部分为隐伏断裂控矿的事实,笔者以中矿段勘探报告为指导,将龙潭组一段(P_(3)l^(1))中零星碎屑岩容矿的矿体再次梳理,纵横对比构思按断裂型矿体重新圈连,据此实施大量探矿工程验证,探获多条(层)隐伏断裂型矿体(如8#、9#、Ⅱz1、Ⅱz3等);增储资源为矿山可持续发展提供资源保障,并总结了其空间形态、分布规律及标志等特征,为后续矿山地质找矿提供指导意见。The first Primary Carlin-type gold mine in China,‘Zijin Shuiyindong gold mine’,was founded on the basis of‘Exploration geology report of the middle ore block of Shuiyindong gold Mining area,Zhenfeng County Province’,it is concluded that the fragmentary clastic rock(calcareous sandstone type in the report)orebody has become the main target of mine exploration for upgrading and increasing reserves,based on the fact that some of the detrital rock type orebodies are controlled by concealed faults,it’s combed the ore bodies containing the sporadic detrital rock in the first member of the Longtan Formation(P_(3)l^(1))again under the guidance of the exploration report of the middle ore section,the vertical-horizontal correlation is designed to re-circle the ore bodies according to the fault type.Based on this,a lot of prospecting projects have been carried out to verify and many concealed fault type ore bodies(such as 8#,9#,IIZ1,IIZ3,etc.)have been found,it sums up the characteristics of its spatial form,distribution law and marks,and provides guidance for the geological prospecting of the following mines.
