| 摘要: |
| 以殷家沟剖面为主,探讨了银母寺铅锌矿床含矿地层的沉积环境,提出含矿地层主要为生物礁相岩石。矿床是在成岩期由含矿热卤水沿断裂多次上升、交代沉淀在礁顶相岩石中形成的。礁相岩石为含矿热卤水交代沉淀提供了有利的物化环境及场所。 |

| Abstract: |
| The sedimentary environments of the ore-bearing strata within the Yingmusi lead-zinc deposit are discussed exemplified by the Yingjiagou section. The ore-bearing strata consist significantly of organic reef facies rocks. The ore deposit was formed by the multistage upward flowing,metasomatism and precipitation of the ore-bearing hydrothermal brines in the rocks of the reef-cap facies. The reefal rocks are considered to be the favourable locus for the metasomatism and precipitation of the ore-bearing hydrothermal brines. |
