摘    要:在地质调查的基础上,介绍了华北陆块南缘近期发现的栾川赤土店Zn-Pb矿床地质特征,测定了矿床S、Pb、H、O等同位素、稀土元素、流体包裹体成分和温度。研究表明矿床具有鲜明的层控特征,含矿地层为新元古界栾川群煤窑沟组,矿体产在碎屑岩与碳酸盐岩转换部位,总体呈层产出,并与含矿地层形成同步褶皱,附近又有桶柱状矿体与层状矿体相连,矿石成分层明显,矿石为块状-层纹状构造,矿体底板蚀变强烈。作者认为该矿床应属于SEDEX型矿床。

关 键 词:栾川赤土店  SEDEX铅锌矿床  新元古代  层控铅锌矿  华北陆块南缘

Abstract:This paper gives an introduction of the geological characteristics of the Chitudian Lead-zinc-(silver) deposit in Luanchuan County,Henan Province,which is located in the South Margin of North China Craton and discovered recently.It also presents the data of S,Pb,H,O isotopes,trace elements,and chemical compositions and microthermometry of fluid inclusions of the deposit.It's suggested that the ore body is strata-bounded,and the host strata is Meiyaogou Formation of Luanchuan Group in Neoproterozoic.The ore body,Which is stratum-like,is located where the clastic rocks converted to carbonate rocks,and sin-folded with the host rock.And also there is a column-like ore bodies jointed with the stratum-like ones.And in view of the fact that minerals form different assemblage layers,ore is massive to bedded structure and strongly altered footwall.We proposed that it is a SEDEX type ore deposit.
Keywords:SEDEX type deposit  Neeproterozoic  strata-bounded lead-zinc deposits  South Margin of North China Craton
