本文论述了南京栖霞山铅锌矿中伴共生金银矿的重要经济价值以及地质找矿意义。
Associted gold appears mainly a independent mineral,natural gold ore and associted silver appears a independent silver mineral,acanthite etc.are two main typies of associted minerals. Paragenetic gold and silver ores which is median sized and distributed in ore block of Pingsh- antou are closely related to oxidized and mixed ores ores in upper orebodies,and are genetic- ally connected with lead-zinc ores.Paragenetic gold and silver ores which have met the needs for industrial grade can be used as a independent mineral.Associted or paragenetic gold and silver ores have an important geoeconomic value.According to 77.8%of the present recovery, 54.88% of reclamation rate,associted and paragenetic ores can reach a value of 900m Yuan.
