火山成因矿床

研究和对比表明，火山成因块状硫化物矿床黄铁矿的Co、Se含量和Co/Ni比值有随矿床年龄变年轻而降低之趋势。

Investigation and comparison indicate that Co and Se contents and Co / Ni ratios of pyrite in volcanogenic massive sulfide deposits tend to decrease with the decrease of their ages .

研究了北祁连山造山带火山成因块状硫化物矿床（VMS）类型、金属来源与容矿围岩、火山岩类型及其构造环境的关系。

The relationships between VMS types , source of metal , host rock , volcanic rock types and tectonic setting have been studied in this paper .
