| 摘 要： | 目前在扬子北缘已发现的铅锌矿床主要分布于震旦系地层中,新近发现的多个大、中型铅锌矿床表明区域找矿潜力巨大.通过对扬子北缘震旦系中铅锌矿形成的含矿建造、控矿构造、岩相古地理、地质流体等成矿条件的系统研究,分析区域成矿的特点,认为区域含矿地层主要为震旦系灯影组白云岩,成矿金属来源于震旦纪-寒武纪地层,成矿流体主要来自海水,有大气降水的加入,矿床形成受背斜(穹窿)构造控制.初步建立铅锌矿的成矿模式,以期服务于本区铅锌矿床的勘查与研究.

| Abstract: | The found lead-zinc deposits in the northern margin of Yangtze Landmass are mainly hosted in Upper Sinian,where is of enormous prospecting potential.The ore-bearing formation,ore-controlling structure,lithofacies paleogeography and geological fluid of lead-zinc deposits are studied to analyze its regional metallogenitic characteristics.Therefore,the results are concluded as follows:the dolomite of Dengying formation in Sinian is main regional ore-bearing bed;ore-forming metals are derived from the Sinian-Ca... |
