摘要
尖端山铅锌矿床与八方山铜—铅锌矿床的成矿类型及控矿因素是类似的。八方山—尖端山倒转背斜的倾伏部位和较陡翼部是矿体的主要赋存部位,而其次级背斜、局部向斜部位亦是成矿的有利部位,深部钻探资料表明尖端山背斜南翼矿体有向SW倾伏趋势,具有形成隐伏矿体的潜力。由此,推测尖端山背斜以南相邻的八方山—尖端山背斜的次级向斜部位有隐伏矿体存在的可能性,应该作为今后寻找隐伏矿体的主要远景区。
The metallogenic types and ore control factors of the Jianduanshan lead-zinc deposit are similar to that of the Bafangshan copper-lead-zinc deposit. The major occurrences of ore bodies are located in prone position and steep flanks of overturned anticline of Bafangshan-Jianduanshan. The favorable positions for metallogenesis lie in secondary anticline and syncline locally. Deep drilling has indicated that ore bodies occurring in the south flank of the Jianduanshan anticline prone to pitch at southwest directrion, with a potential for concealed ore bodies. Hence, it is estimated that it is possible for concealed ore bodies occurring in secondary syncline near by Bafangshan-Jianduanshan anticline, which would be a major prospective area for finding out concealed ore bodies in future.
