南京东郊栖霞山矿区,五十年代还只是一个小型的氧化锰矿床。经过多年的找矿勘探,现已探明为一大型铅锌锰多金属矿床。区内断裂是重要的控矿构造。据近年来的勘探和地质研究,笔者发现除断裂以外,古岩溶对于控矿构造的形成起着重要作用,它不但在碳酸盐岩地层中形成了一些特有的容矿空间,而且扩大加宽了古岩溶以前印支期所形成的断裂和裂隙,使之成为良好的容矿构造。根据古地文条件分析,古岩溶还具分带性,它对容矿构造的发育程度、空间分布及矿体形态均有影响。
The Qixia Mountain mining area on the eastern outskirts of Nanjing was only a small manganese oxide deposit in the 1950s. After years of prospecting exploration, has now been proven as a large lead-zinc-manganese polymetallic deposits. The fault in the area is an important ore control structure. According to the exploration and geology research in recent years, the authors found that besides the faults, the ancient karstification plays an important role in the formation of ore-controlling structures. It not only forms some unique ore-holding spaces in carbonate stratum, but also widens the widening Before the ancient karst Indo-Chinese-formed fractures and cracks, making it a good ore-bearing structure. According to the palaeontological conditions analysis, ancient karst also has zonation, which has an impact on the development degree, spatial distribution and ore body morphology of the ore-hosting structure.
