【摘要】 黄陵断穹北部分布有许多与上震旦统灯影组粉晶云岩有关的铅锌矿点(床)。为了总结这类矿床的基本特征,进一步指导找矿工作,从成矿地质背景入手,研究了凹子岗锌矿区的赋矿地层、控矿构造、矿体特征、矿石特征。结果表明:凹子岗锌矿形成与岩相古地理密切相关,属局限海潮下相沉积—成岩型矿床;宜昌县黑良山铅锌矿点及铅锌异常规模大,异常组合好,具有寻找凹子岗式(铅)锌矿的找矿前景,是今后普查评价的工作重点。更多还原

【Abstract】 There are many lead-zinc ore spot(deposit)related to silt-crystalline limestone of Dengying Formation in Upper Sinian,which distribute in north of Huangling faulted dome.In order to sum up the basic characteristics of this kind deposit for guiding further prospecting,starting from metallogenic geological background,the authors study the ore-bearing strata,ore-controlling structure,orebody and ore feature of Aozigang zinc mining area.The results show as follows:Aozigang Zinc deposit belongs to sedimentary-diagenetic one in restricted tidal lower phase,formed related closely to lithofacies paleogeography;especially in Heiliangshan lead-zinc ore spot,Yichang County,both large anomaly scale and preferable anomaly association result in huge prospecting for Aozigang type(lead)zinc deposit,which is point of future survey and should be paid more attentions.更多还原
